Abstract: In an orientation division type liquid crystal display device for widen a viewing angle of a display pixel of an active matrix type liquid crystal color display device having a COT structure, pixel color layers (6B, 6R, 6G) as color filters and pixel electrodes 3 are formed on a substrate on the side of the pixel electrodes and slopes 13 are provided along four side peripheries of each pixel electrode. Liquid crystal molecules 8 between each pixel electrode of the pixel electrode substrate and a common electrode of an opposing substrate are controlled in orientation direction along the slopes to divide it to a plurality of directions to thereby widen a viewing angle of a pixel display. The slope is formed on a step portion 12 formed by a BM layer formed on at least one of a gate electrode, a drain electrode and a source electrode formed in a periphery of the pixel electrode or at least one of a gate wiring and a drain wiring formed in the periphery or a step portion formed by partially overlapping peripheral portions of the adjacent pixel color layers.

Abstract: An active matrix liquid crystal display device which has color filters disposed on a TFT (Thin-Film Transistor) substrate, and which reduces the effect of light leakage regions over data lines for an increased viewing angle. The liquid crystal display device has the data lines disposed on the TFT substrate at respective gaps between adjacent two of pixel electrodes, for supplying data signals to TFTs to drive pixel electrodes, and a black matrix disposed on the TFT substrate in association with the data lines for blocking light passing in a predetermined viewing angle range through a light leakage region created in the liquid crystal layer depending on a potential difference between adjacent two of the pixel electrodes.

Abstract: A liquid-crystal display (LCD) device improves the performance of preventing the elution of impurity contained in the light-shielding layer (and the color layer) of the monochrome or color filter into the liquid crystal, thereby preventing defective operations of the LCD device (e.g., displaying defect) caused by impurity existing in the liquid crystal. The LCD device includes the protection layer made of a transparent organic resin, which satisfies at least one of a condition (a) that the transparent organic resin has a cross-link density of 70% or greater, and a condition (b) that the transparent organic resin has a Vickers hardness of 50 kgf/mm2 or greater. Preferably, an amount of internal impurity of the filter is 3 ng/cm2 or less. It is preferred that at least one selected from the group consisting of an acrylic resin, a styrene resin, and a polyimide resin is used as a base or matrix material of the transparent organic resin.
