Abstract:
1. A liquid crystal display (LCD) device comprising: an active matrix substrate mounting thereon a plurality of pixels each including a switching device, said active matrix substrate having an alignment film at a topmost surface thereof; a counter substrate opposing said active matrix substrate with a gap therebetween defined by a plurality of columnar spacers; and a liquid crystal layer sandwiched between said active matrix substrate and said counter substrate, said active matrix substrate having a plurality of active spacer holes and a plurality of dummy spacer holes each having dimensions substantially the same as the dimensions of said active spacer holes, wherein the dummy spacer holes and the active spacer holes are formed in the same layer, wherein some of said dummy spacer holes are aligned with some of said active spacer holes in a rubbing direction of said alignment film, and wherein the plurality of active spacer holes and the plurality of dummy spacer holes together exceed in number the plurality of columnar spacers, and said columnar spacers are located and received only in the active spacer holes.
