Abstract
A liquid crystal display device having pillar-shaped spacers formed in pixel array regions is provided with improved display quality by preventing the degradation of contrast and the occurrence of residual images. A plurality of pillar-shape spacers formed in their pixel array regions are provided at locations which do not overlap with each other when images are projected on the screen using three different liquid crystal light valves to project the red (R), green (G) and blue (B), constituents of images.
