摘要:
A liquid crystal display device comprises a first substrate, a columnar spacer formed on the first substrate and exhibiting light shielding properties, an alignment film formed to covet at least a part of the columnar spacer, a second substrate arranged to face the first substrate with a predetermined gap provided by the columnar spacer between the first and second substrates, and a liquid crystal material arranged within the gap. The columnar spacer is tapered in the forward direction as viewed from the first substrate in that portion of the columnar spacer which is positioned closest to the second substrate and has the largest diameter portion in the region other than that region of the columnar spacer which is positioned closest to the first substrate.
