Description

technical field [0001] The present invention relates to a pixel array, and in particular to a pixel array with good display quality, a liquid crystal display panel and an optoelectronic device. Background technique [0002] As liquid crystal displays continue to develop towards large-size display specifications, in order to overcome the viewing angle problem under large-size displays, the wide viewing angle technology of liquid crystal display panels must also continue to improve and break through. Among them, a multi-domain vertical alignment (MVA) liquid crystal display panel and an advanced multi-domain vertical alignment (Advanced MVA, AMVA) liquid crystal display panel are currently common wide viewing angle technologies. Since the advanced multi-domain vertical alignment (AMVA) liquid crystal display panel can effectively improve the color washout problem (color washout) in the multi-domain vertical alignment (MVA) liquid crystal display panel, therefore, compared with...
