The present invention relates to an in-plane switching liquid crystal display comprising a negative biaxial retardation film and a positive C-plate, as viewing-angle compensation films. By the use of such viewing-angle compensation films, the contrast characteristics at the front side and inclination angle of the in-plane switching liquid crystal display can be improved and color shift with viewing angle in the dark state can be minimized.

Disclosed is a liquid crystal panel (2) wherein an upper layer electrode (14) and a lower layer electrode (12) are provided by being superimposed by having an insulating layer (13) therebetween on one substrate (10) of a pair of substrates (10, 20) facing each other with a liquid crystal layer (30) therebetween. The upper layer electrode (14) is composed of comb-like electrodes (14A, 14B), and the average electric energy at the position 0.1 [mu]m from the surface of the other substrate (20), on the portion which overlaps the comb-like electrodes (14A, 14B) when the liquid crystal layer (30) is viewed from the direction perpendicular to the substrate surface, is 0.44 j / m3 or more.

The present invention provides a method of producing a latent polarized image having high contrast characteristics with no apparent contours or traces of the image under normal visualization. A polymer solution is prepared in an organic solvent, and then applied onto a light-reflecting substrate. The polymer layer is dried to produce an optically isotropic polymer layer and anisotropic images are formed on the polymer layer. The polymer solution's concentration is from 5 to 30% by weight, and the images are formed by application of micro-lines by thermo-mechanical means, having depths from 1 to 3 μm and being separated from one another by 4 to 6 μm at a process rate from 10 to 50 m / min. The thermomechanical means operates at a temperature that is 10 to 60% less than the polymer melting / disintegration temperature and contacts the polymer layer to form micro-lines for 0.015 to 0.650 msec.

More specifically, it is characterized in that it contains a compound represented by the following chemical formula 1, [chemical formula 1] (X + ) n (Y) m‑ By containing the compound represented by the specific chemical formula, the above-mentioned colored photosensitive resin composition exhibits high reliability and high contrast characteristics without reducing the brightness when applied to a color filter and an image display device having a color filter. A color filter produced from the above-mentioned colored photosensitive resin composition and an image display device including the color filter have an effect of being excellent in sensitivity.

The present invention provides a plasma display apparatus which can improve a driving waveform and enhance driving margin and optical characteristic when motion images are outputted. The plasma display apparatus includes a first electrode formed in a panel, and a first electrode driver configured to apply a driving waveform to the first electrode, wherein the first electrode driver applies different driving waveforms when motion images are output and when still images are output. In the plasma display apparatus constructed as described above according to the present invention, images are divided into still images and motion images. In the motion images, as a motion change increases, a driving waveform is varied by decreasing the number of set-up signals or sustain pulses, or by lowering a set-up voltage. Accordingly, the distortion of an image occurring as waveforms are varied can be minimized. Furthermore, there are advantages in that the margin of a driving signal can be enhanced, heat generated from a panel can be reduced, and damage to the panel can be prevented. In particular, there is an advantage in that a contrast characteristic of an image can be improved.
