Liquid crystal display panel and liquid crystal display device

摘要

The present invention provides a liquid crystal display panel and a liquid crystal display device having excellent display quality, with reduced string-like defects that occur in display pixels. The liquid crystal display panel of the present invention includes multiple spacers between a pair of substrates, wherein the spacers are arranged such that an inter-spacer distance between adjacent spacers in a longitudinal direction is different from an inter-spacer distance between adjacent spacers in a transverse direction, and an angle formed between a line connecting the spacers with a shorter inter-spacer distance and an alignment direction of liquid crystal molecules at a voltage lower than a threshold voltage in the liquid crystal layer is 20° or smaller.

主权项

1. A liquid crystal display panel comprising:
a pair of substrates; and a liquid crystal layer interposed between the pair of substrates, wherein at least one of the pair of substrates includes a photo-alignment film and an electrode in the stated order from the liquid crystal layer side, the photo-alignment film aligns liquid crystal molecules horizontally to a main surface of the at least one of the pair of substrates, the liquid crystal display panel includes multiple spacers between the pair of substrates, the spacers being arranged such that an inter-spacer distance between adjacent spacers in a longitudinal direction is different from an inter-spacer distance between adjacent spacers in a transverse direction in a plan view of the main surface of the pair of substrates, and an angle defined between a line connecting the spacers with a shorter inter-spacer distance than the other inter-spacer distance and an alignment direction of the liquid crystal molecules at a voltage lower than a threshold voltage in the liquid crystal layer is 20° or smaller as seen in a plan view of the main surface of the at least one of the pair of substrates.
