Abstract
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, whose corner portions are chamfered, is formed at each position partitioned by scanning linesand signal linesthat are arranged in a matrix state, in which a protruding electrodeextending from the pixel electrodeis formed between the chamfered position of the corner portion and the scanning lineto 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.
