Abstract
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 substrateopposing first group post-like spacers, for each pixel, a step filmis formed by adequately combining by one or more floating inorganic film layers (for instance chromium layersand, an aluminum layerand am amorphous silicon layer). The first gap post-like spacersare each in contact with the step filmat all times. The inorganic step filmis not formed on each of parts of the array side substratecorresponding to second group port-like spacers, respectively, thus providing a gap. The thickness of the step filmis preferably set to 2,000 Å to 5,000 Å.
