发明名称 Liquid crystal display device comprising post-like spacers in contact with a step film having a thickness between 2,000 Angstrom to 5,000 Angstrom
摘要 A liquid crystal display device, which uses post-like spacers for eliminating local gap irregularity generation and permitting improvement of black view non-uniform irregularities and lower part gap irregularities, is disclosed. On an array side substrate 201 opposing first group post-like spacers, for each pixel, a step film 100 is formed by adequately combining by one or more floating inorganic film layers (for instance chromium layers 41 and 43 , an aluminum layer 42 and am amorphous silicon layer 31 ). The first gap post-like spacers 304 are each in contact with the step film 100 at all times. The inorganic step film 100 is not formed on each of parts of the array side substrate 201 corresponding to second group port-like spacers 304 , respectively, thus providing a gap. The thickness of the step film 100 is preferably set to 2,000 Å to 5,000 Å.
