Abstract:
A multi-domain vertical alignment mode liquid crystal display comprising:a driving electrode layer in which driving electrodes corresponding to pixels are two-dimensionally arranged; a transparent electrode layer for generating, together with the driving electrode layer, an electric field between driving electrode layer and the transparent electrode layer, provided in parallel with the driving electrode layer at a predetermined distance; spacers for keeping the predetermined distance, provided as pillars or ribs between the driving electrode layer and the transparent electrode layer; a liquid crystal layer comprising liquid crystals having negative dielectric anisotropy, placed between the driving electrode layer and the transparent electrode layer; vertical alignment layers for vertically aligning the liquid crystals, respectively provided on the driving electrode layer side surface and the transparent electrode layer side surface of the liquid crystal layer; alignment-controlling projections for controlling the direction of alignment of the liquid crystals, linearly provided on the liquid crystal layer side surface of the driving electrode layer and/or that of the transparent electrode layer; and a color layer having a colored pixel pattern of two or more colors, wherein the spacers are provided over the alignment-controlling projections; each spacer has at least one pair of side faces that are parallel to the linear direction of the alignment-controlling projection; and the area of the alignment-controlling projection encompasses the area of the spacer, or the area of the spacer partially or entirely extends beyond the area of the alignment-controlling projection, the gap between the alignment-controlling projection and the side face of the spacer extending beyond the alignment-controlling projection in the latter case being not more than 7 &mgr;m when observed in the vertical direction against the driving electrode layer, and wherein the alignment-controlling projections are provided as zigzag lines arranged in parallel stripes, each zigzag line having turnings at a predetermined interval with a bent angle of 90 degrees.
