A liquid crystal display panel includes: a pair of substrates which are opposed to each other; and a liquid crystal layer which is interposed between the pair of substrates, wherein one of the pair of substrates is provided with a plurality of scanning lines and a plurality of signal lines which are arranged in a matrix shape in a display area, lower electrodes which are each formed in each of sub-pixel areas partitioned by the plurality of scanning lines and the plurality of signal lines, an insulating film which is formed in the display area so as to cover the lower electrodes, upper electrodes which are formed in the display area through the insulating film and each have a plurality of slits in each of the sub-pixel area, and an alignment film which is formed on the upper electrodes and slit-shaped openings close to the liquid crystal layer, wherein the other of the pair of substrates is provided with light-shielding films which are formed at locations overlapping with the scanning lines and the signal lines in plan view, wherein each of the upper electrodes overlaps with each of the light-shielding films in at least a partial portion in plan view, wherein each of the slit-shaped openings extends along any one of the signal line or the scanning line and has a main portion extending in an direction inclined at a predetermined angle with respect to a rubbing direction of the alignment film and a front end portion, and wherein an edge of the circumference of at least one of the slit-shaped openings formed on both sides of the light-shielding film so as to dispose the light-shielding film therebetween in plan view does not overlap with the light-shielding film disposed between the slit-shaped openings in plan view.

There is provided an ink-jet printer including: an ink supply source; an ink-jet head in which a plurality of nozzle groups corresponding to a plurality of color inks are formed; a maintenance mechanism; a controller which controls the ink-jet head and the maintenance mechanism; and a filling liquid filled in the ink jet head in a state before the ink-jet printer is used for the first time, wherein, in the state before the ink-jet primer is used for the first time, the controller controls the maintenance mechanism and the ink-jet head to perform an initial discharge operation; and an amount of a liquid discharged from the ink-jet head during the initial discharge operation is adjusted based on a color difference between one of the plurality of color inks and a replaced-ink.

The present invention relates to a light emitting diode and a method of fabricating the same, wherein the distance between a fluorescent substance and a light emitting diode chip is uniformly maintained to enhance luminous efficiency. To this end, there is provided a light emitting diode comprising at least one light emitting diode chip, lead terminals for use in applying electric power to the light emitting diode chip, and a frame that is used for mounting the light emitting diode chip thereon and is formed to have a predetermined height and a shape corresponding to that of the light emitting diode chip.

An optical sheet comprising: a transparent substrate; a light diffusion layer having a surface roughness structure which is provided on one surface of the transparent substrate; and a light diffusion adhesive layer provided on the other surface of the transparent substrate, wherein the light diffusion layer comprises a resin and first diffusion particles having a number-average particle size of 1.7 mum or above, the light diffusion adhesive layer comprises a binder, highly refractive nanoparticles and second diffusion particles, and the relationship x1 > x2 is satisfied, where the haze of the light diffusion layer is x1 (%) and the haze of the light diffusion adhesive layer is x2 (%); and a surface light source apparatus provided with said optical sheet and an organic electroluminescent light-emitting element.

The piston dispenser for the measured supplying of material to the atomizer of a painting robot is arranged in the hand joint of the robot. Various feasible embodiments of the dispensing cylinder of this piston dispenser are described.

Provided are a light-emitting device package and a method of manufacturing the same. The light-emitting device package may include a plurality of light-emitting chips on one substrate (board). The plurality of light-emitting chips may produce colors around a target color. The target color may be produced by combinations of the colors of light emitted from the plurality of light-emitting chips. The colors around the target color may have the same hue as the target color and have color temperatures different from that of the target color. The plurality of light-emitting chips may have color temperatures within about ±250K of that of the target color.

An image forming apparatus includes an image forming unit configured to form a measurement image on a recording paper by using a color material, a fixing unit configured to fix a plurality of measurement images onto the recording paper by heating the measurement images, a measurement unit configured to measure the measurement images fixed onto the recording paper downstream of the fixing unit in a conveyance direction of the recording paper, a cooling unit configured to cool the recording paper heated by the fixing unit, and a control unit configured to perform control such that a cooling capacity of the cooling unit in a case where the measurement unit measures color of the measurement images is higher than a cooling capacity of the cooling unit in a case where the measurement unit measures density of the measurement images.
