Liquid crystal display panel

摘要

An MVA type liquid crystal display panel of the present invention comprises a first substrate where a light transmission section consisting of a pixel electrode 15a, whose corner portions are chamfered, is formed at each position partitioned by scanning lines 13 and signal lines 14 that are arranged in a matrix state, in which a protruding electrode 40 extending from the pixel electrode 15a is formed between the chamfered position of the corner portion and the scanning line 13 to prevent the inclination of liquid crystal molecules due to the effect of the potential difference occurring between the scanning line and a common electrode. According to the present invention, it is possible to provide an MVA type of liquid crystal display panel having high contrast, where contrast reduction caused by the inclination of liquid crystal molecules due to the effect of the potential difference occurring between the scanning line and a common electrode is controlled, even where the liquid crystal display panel employs pixel electrodes with chamfered corner portions.

1. A liquid crystal display panel, comprising:
a first substrate where a pixel electrode, whose corner portions are chamfered, is formed in each position partitioned by signal lines and scanning lines that are arranged in a matrix state; a second substrate on which a common electrode is formed; alignment films of vertical alignment treatment, which are severally laid on both of the said substrates; and a liquid crystal layer having negative dielectric anisotropy, and being arranged between both of the said substrates, wherein the pixel electrode includes a protruding electrode symmetrically protruding from the pixel electrode in opposite directions along the scanning line and extending along the scanning line, the protruding electrode being formed between the chamfered corner portions of the pixel electrode and between the pixel electrode and the scanning line to prevent the inclination of liquid crystal molecules residing at the chamfered corner portions and reduction of contrast.
