A plasma display panel having a light absorption reflection film that does not reflect light emitted from a discharge space in a non-discharge region includes: a rear substrate; a plurality of address electrodes arranged on a surface of the rear substrate; a rear dielectric layer arranged on the rear substrate to cover the address electrodes; a plurality of barrier ribs arranged on the rear dielectric layer to define discharge cells; a front substrate facing the rear substrate; a plurality of sustaining electrode pairs composed of X and Y electrodes; a light absorption reflection film including a first light absorption reflection film arranged between the adjacent sustaining electrode pairs and a second light absorption reflection film having a different width than that of the first light absorption reflection film, the second light absorption reflection film arranged on a lower surface of the first light absorption reflection film; and a front dielectric layer arranged on a lower surface of the front substrate to cover the X and Y electrodes and the light absorption reflection film.

An external light-shielding layer capable of enhancing a visible light transmittance and a contrast ratio and preventing Moire fringe and Newton ring phenomena, a display filter including the external light-shielding layer, and a display device including the display filter. The external light-shielding layer includes a transparent resin matrix, and a plurality of light-shielding patterns formed on the transparent resin matrix and spaced apart from each other in a predetermined interval, wherein a bias angle (α) formed between a traveling direction of the light-shielding patterns and the longer side of the matrix is in a range of about 5 to 80 degrees.

A color filter (200) comprises pixels (13) separated from each other by partitions (14) formed on a substrate (12) so as to have a plurality of color elements of ink. Dummy pixels (13′) are formed outside the area in which the pixels (13) are formed. The amount of ink applied to each of said pixels and the amount of ink applied to each of said dummy pixels are substantially equal. A protective film (21) covering said pixels (13) is formed so as to also cover said dummy pixels (13′).

A protective plate for a plasma display includes conductive substrate for protecting a plasma display and an electrode in electrical contact with the conductive substrate.

A plasma display apparatus is capable of enhancing the heat dissipating ability of a plasma display panel, and of reducing the total weight of the plasma display apparatus. The plasma display apparatus comprises a plasma display panel, a frame to which the plasma display panel is attached and by which the plasma display panel is supported, and a boss plate fixed to a rear surface of the frame and fitted with driving circuit boards. The frame is formed in the shape of a rectangular frame which contacts edges of the plasma display panel. A vertical member is vertically disposed in the rectangular frame. The vertical member has wall-mounted bosses which support the total weight of the plasma display apparatus. Other features include a thermally conductive member formed on the rear surface of the frame, and formation of an air passage between the thermally conductive member and the driving circuit boards.

A discharge inert film (22) is made of an aggregate of fine particles not substantially containing any inorganic binder. Each of sustain discharge electrodes (XB, YB) includes a plurality of discharge gap adjoining portions (a), a bus portion (b) and a plurality of bridge-building portions (c). The bus portion (b) adjoins the electrode pair gap portion (NG), extending along a second direction (D2). Each of bridge-building portions (c) extends towards a discharge gap portion (DG). The bridge-building portions (c) are connected to the discharge gap adjoining portions (a), respectively, and these adjoining portions (a) adjoin the discharge gap portion (DG) and are arranged therealong. The film (22) is so disposed as not to cover the discharge gap adjoining portions (a). When a surface discharge is generated between the sustain discharge electrodes (X, Y) during a reset period, the potential difference between the electrodes (X, Y) is gradually increased.

A display filter for use with a plurality of microlenses in a display system includes an external light and electromagnetic (EM)-shielding portion having a photosensitive transparent resin layer with a photocatalyst, and an external light and EM-shielding pattern formed on regions of the photosensitive transparent resin layer to prevent external light from entering the display system and to prevent EM waves generated in the display device from exiting the display device, the regions corresponding to boundaries between the plurality of microlenses.

A near infrared screening film which consists of a biaxially oriented film made from a polyester containing a near infrared light absorber having a weight reduction start temperature of at least 280° C. and which has a haze value of 5% or less and a total transmittance for visible lights having a wavelength of 400 to 650 nm of 40% or more and which is exemplified by having optical properties at visible and near infrared ranges which satisfy the following expressions (1) to (4):1<T(850)<20  (1)1<T(950)<20  (2)−10<T(620)−T(540)<10  (3)−10<T(450)−T(540)<10  (4)wherein T(450), T(540), T(620), T(850) and T(950) are light transmittances at wavelengths of 450 nm, 540 nm, 620 nm, 850 nm and 950 nm, respectively.This film is inexpensive, has high handling ease, a high visible light transmittance and the function of preventing the malfunction of peripheral equipment caused by near infrared lights from the screen of a plasma display, for example, and can be suitably used in the front panel of the plasma display.
