摘要： A improved liquid crystal display device including two substrates each having transparent electrode thereon disposed in parallel while keeping a predetermined gap by means of pillar-shaped spacers and a liquid crystal held between said first and second substrates is proposed. In the liquid crystal display device, density or volume of the number of the pillar-shaped spacers provided in the off-display area is higher than those of a density of the number of said pillar-shaped spacers provided in the display area. This change is made continuously or stepwise along areas. The spacers are preferably disposed so that a contact area between the spacer and a rubbing cloth during the rubbing process is minimized, or so that an orientation defective area caused starting from the spacer does not extend into the pixel area, or so that a plurality of spacers are disposed along a flow of liquid crystal from filling port into the gap between the first and second substrate.

摘要： A color filter substrate has a substrate structure, spacers which include a first spacer layer and a plurality of second spacer layers. Each of the second spacer layers has a sectional plane which is substantially parallel to the substrate structure. And the sectional plane has a entire projective area of the first spacer layer therein and an elongated portion from the projective area, so that an area of effective thickness of the spacer to maintain the gap between two substrates depends on an area of a smaller of the first and second surfaces of the first spacer layer. In other words, the outline of the first spacer layer is located so as to be entirely included within the outline of these second spacer layers. If the central axis of the first spacer layer is shifted from that of the second spacer layers in the manufacturing process of the liquid crystal display apparatus, misalignment between first and second spacer layers occurs. The degree of the misalignment depends on the accuracy of the photo-etching technique. On account of the portion, above misalignment is absorbed and the first spacer layer is entirely located on the second spacer layers. In this occasion, the effective thickness of the spacer is established over the whole projective area of the first spacer layer on the substrate, Therefore, regardless of the position within the liquid crystal display apparatus panel or the production lot, the gap uniformity between two substrates is gained. An island shape spacer is positioned at the liquid crystal injection area, so that the gap between the two substrates at the liquid crystal injection area is uniform.

摘要： A liquid crystal display element includes a pillar-shaped spacer as a stack of a plurality of color layers, which exists on either an active matrix substrate or an opposite substrate facing to the former substrate. An impurity concentration and an impurity elution quantity of the color layer closest to a switching element among the color layers constituting the pillar-shaped spacer are made lowest among the plurality of color layers, or a bridging density of a resin is made highest among the color layers, thereby restraining an influence of the impurities upon the switching element and enhancing a display quality and a yield. Damages to contact areas when the active matrix substrate is disposed facing to the opposite substrate are reduced by making a hardness of the farthest layer from a surface of a substrate on which the pillar-shaped spacer is disposed lowest among the color layers.

摘要： A spacer is constructed of a stacked colored layers constituting color filters and is disposed in such a position as to exhibit a high dielectric breakdown strength on an active matrix substrate. A display performance is enhanced because of using no plastic beads, and insulation can be maintained. When the spacer assumes an inversely tapered shape, a contact position of the spacer can be freely selected because of forming no conductive layer on side surfaces.
