In an organic EL display device, an organic EL board (100) wherein an organic EL element (40) is formed on a first board (10), and a color conversion board (200) wherein a color conversion layer (70) is formed on a second board (60) are arranged by permitting the organic EL element (40) to face the color conversion layer (70). A transparent wall (80) which is thicker than the color conversion layer (70) is provided between the color conversion layers (70) of the color conversion board (200). The wall (80) is a partition wall for separating the color conversion layer (70), and is also a spacer between the organic EL board (100) and the color conversion board (200). A sealing medium (90) is provided between the walls (80) with the color conversion layer (70).

A semiconductor device (100A) has: a substrate (2); an oxide semiconductor layer (5) formed on the substrate (2); a source electrode (6s) and a drain electrode (6d) which are electrically connected to the oxide semiconductor layer (5); a first transparent electrode (7) which is electrically connected to the drain electrode (6d); a dielectric layer (8) formed on the source electrode (6s) and the drain electrode (6d); and a second transparent electrode (9) formed on the dielectric layer (8). The upper surface and / or lower surface of the first transparent electrode (7) contact(s) a reducing / insulating layer (8a) having a property that reduces the oxide semiconductor included in the oxide semiconductor layer (5). At least part of the second transparent electrode (9) overlaps the first transparent electrode (7) with the dielectric layer (8) interposed therebetween. The oxide semiconductor layer (5) and the first transparent electrode (7) are formed from the same oxide film.

An object of the present invention is to provide a photocurable inkjet ink with low volatility, which is useful in the manufacture of microlenses or electronic components. The photocurable inkjet ink of the present invention contains a polyfunctional (meth)acrylate (A), has a non-volatility of 75% or more in Evaluation Method 1, and has a viscosity of 1 mPa·s to 70 mPa·s (25°C). Monofunctional (meth)acrylate (B) and photopolymerization initiator (C), and the viscosity at 25°C is 1mPa·s~100mPa·s; [Evaluation method 1] the monofunctional (meth)acrylate (B): The weight ratio of pentaerythritol tetra(tri)acrylate=25:45 was mixed, and the evaluation liquid was produced. (1) The weight of the glass substrate of 5 cm x 5 cm was measured. (2) The evaluation liquid was dripped on the glass substrate of (1), and it applied so that a coating weight might become the error of 25 mg±2 mg by spin coating. (3) The weight of the glass substrate coated with the evaluation liquid of (2) was measured. (4) The weight of (1) was subtracted from the weight of (3) to calculate the coating weight of the evaluation liquid. (5) The glass substrate coated with the evaluation liquid in (3) was heated on a 50° C. hot plate for 15 minutes. (6) Measure the weight of the heated glass substrate of (5), subtract the weight of (1), and calculate the remaining amount of the evaluation liquid. (7) Calculate the non-volatility according to the following formula. Non-volatility % = balance ÷ coating weight x 100.

There is provided a PDP and an image display apparatus equipped with the same, in which the deterioration in the address discharge timelag with age is suppressed, which is bright, has guaranteed life, can stably be driven, is of low power consumption, high definition, and high image quality. There is provided a pair of sustaining discharge electrodes on the front substrate extending in a row direction for forming a display line, a floating electrode not connected to an external electrode is arranged on the same substrate as the pair of sustaining discharge electrode so as not to pass through a center line extending in a column direction and dividing the discharge cell into two equal parts, thereby intensifying the local potential of an area of the MgO surface not influenced by the sputtering by the sustaining discharge in the address discharge, promoting the electron emission from this area, and suppressing the deterioration of the address discharge timelag.

The invention relates to a toner, a developer, and an image forming method.

The purpose of the present invention is to provide an organic EL element in which a capping layer is combined with various materials of the element so that properties of each of the materials of the element can be effectively demonstrated. The capping layer is constituted from a material that does not affect material inside the organic EL element when sunlight having wavelengths of 400-410 nm is absorbed, that has a high absorption coefficient and a high refractive index in order to greatly improve light extraction efficiency, that gives a thin film having excellent stability, durability and lightfastness, and that does not absorb light in the blue, green and red wavelength regions. The invention relates to: an arylamine compound having a benzoazole ring structure; and an organic EL element having a capping layer that contains the arylamine compound, and a luminescent layer that contains a host and a phosphorescent dopant.

An ink jet recording apparatus includes a first line head that ejects a polymerizable ink containing an active energy radiation-polymerizable compound but substantially not containing a coloring agent onto a recording medium to form an undercoat layer, a second line head that ejects a glittering ink onto the undercoat layer to form a glittering image, a third line head that ejects a coloring ink to form a color image, a transport mechanism that transports the recording medium, an irradiation portion that irradiates the undercoat layer with active energy radiation, and a heating portion that dries the glittering ink. The first line head is disposed upstream from the second line head in the recording medium moving direction, and the third line head is disposed downstream from the second line head in the recording medium moving direction.
