Embodiment 1
[0089] 1A and 1B are schematic diagrams of a typical structure of an LCD device according to an embodiment of the present invention, wherein Figure 1B is a plan view depicting a typical structure, Figure 1A is along the Figure 1B The cross-sectional view taken by the line x-x' in.
[0090] The LCD device includes a pair of substrates such as glass substrates 1 and 2 with a liquid crystal layer 9 interposed therebetween. A sealing member (not shown) for sealing the liquid crystal layer 9 is provided between the substrates 1 and 2 . Columnar spacers are provided at predetermined positions of the liquid crystal layer 9 between the substrates 1 and 2 .
[0091] On the inner surface of the glass substrate 2 facing the liquid crystal layer 9, a strip-shaped signal electrode 4 (made of ITO transparent electrode film, for example) is provided. A vertical alignment layer 5 a of polyimide or the like is located on the substrate 2 and arranged in a striped structure substantially co...

[0105] Referring to FIGS. 3A to 3H, a method of manufacturing an LCD device according to Embodiment 1 of the present invention will be described.
[0106] 3A to 3H are cross-sectional views describing various steps of a method of manufacturing an LCD device.
[0107] In step 3A, a color filter (not shown) comprising R, G and B color portions of each pixel area and a black matrix (not shown) covering intervals between the color portions are formed on one surface of the glass substrate 1. out). Signal electrodes 3 are formed on the color filters and black matrix.
[0108] In step 3B, columnar spacers 7 are formed on a black matrix (not shown) on the glass substrate 1 . The columnar spacers 7 are formed by, for example, adding a photosensitive resin (such as a barrier layer) on the substrate, and patterning the photosensitive resin with a photomask. Thus, columnar spacers 7 can be formed in one patterning step. This eliminates the need for precise alignment as in methods invo...

[0116] Figure 4A with 4B An LCD device according to Example 2 of the present invention is described. Figure 4B is a plan view describing the LCD device, Figure 4A is along Figure 4B The cross-sectional view taken by the line y-y' in .
[0117] exist Figure 4A with 4B In the shown LCD device, an axisymmetric alignment fixing layer 10 is provided on the substrate 1 of each pixel region (ie, in each liquid crystal region 8 ). The vertical alignment layer 5 b is provided on the axis-symmetrical orientation-fixing layer 10 .
[0118] refer to Figure 4A , the thickness of the axisymmetric orientation-fixed layer 10 gradually changes from its maximum value at the columnar spacer 7, and decreases as the distance from the columnar spacer 7 increases until between two adjacent columnar spacers 7 The minimum value is reached at the central axis of . The thickness increases again with decreasing distance to the next columnar spacer 7 . Thus the lowest portion of the axis-s...
