Liquid crystal display panel and liquid crystal display device

摘要

The present invention provides a liquid crystal display panel that has an enhanced liquid crystal alignment controlling force irrespective of the external conditions or environments. The enhanced liquid crystal alignment controlling force sufficiently prevents surface roughness or color unevenness that can occur depending on the viewing angle, so that favorable display qualities and excellent transmittance can be achieved. The liquid crystal display panel includes a pair of substrates comprising a pixel electrode and a counter electrode; and a liquid crystal layer disposed between the substrates, the liquid crystal display panel comprising spacers at at least four corners of a pixel defined by the pixel electrode.

主权项

1. A liquid crystal display panel comprising:
a thin film transistor substrate including a pixel electrode; a counter substrate including a counter electrode; a liquid crystal layer disposed between the thin film transistor substrate and the counter substrate; and spacers provided at at least four corners of a pixel defined by the pixel electrode; wherein the counter electrode includes a hole located at a center of the pixel; the spacers are provided on the thin film transistor substrate and taper towards the counter substrate; the liquid crystal display panel aligns liquid crystal molecules perpendicularly to the substrate surfaces when no voltage is applied; the liquid crystal molecules are aligned in a direction parallel or substantially parallel to a substrate surface of the thin film transistor substrate and aligned along a line extending from the four corners of the pixel towards a center of the pixel when a voltage which is not lower than a threshold voltage is applied; the thin film transistor substrate includes a scanning line; the scanning line is arranged to pass through the center of the pixel; and the hole of the counter electrode is provided in a region where the scanning line is provided.
