Abstract:
1. A liquid crystal display panel comprising: a pair of substrate structures having plural pixels where an image is produced, liquid crystal filling a gap between said pair of said substrate structures and selectively making said pixels dark and bright for producing said image, column spacers formed on one of said substrate structures of said pair and held in contact with the other of said substrate structures, the ratio of the total contact area between said column spacers and said other of said substrate structures to the total area occupied by said plural pixels being within the range from 0.050 percent to 0.150 percent, at least one of said column spacers being formed within a matrix of said plural pixels, said matrix of said plural pixels being formed by rows and columns of said plural pixels, and a sealing layer formed between said matrix of said plural pixels and a peripheral area, and a reservoir formed between said substrate structures for preventing said pair of substrate structures from increasing said gap by accumulating part of said liquid crystal, wherein no column spacers are formed in an area of said sealing layer, and wherein the liquid crystal display panel is an In-Plane-Switching display panel.
