Description
図1は、本発明の実施の形態1における液晶表示装置のRGB各画素の平面図である。図1におけるRGBそれぞれの画素は、円形状にくり抜かれた画素電極10と、コモン電極とを備えている。画素電極10が円形状にくり抜かれているため、図1におけるコモン電極は、円形状に見えている。このように、本発明においては、画素電極10の形状が、n型液晶による液晶分子が種々の方向に傾くように円形状にくり抜かれている点を特徴としている。
本実施の形態2では、実施の形態1とは異なる画素電極10の形状を有する液晶表示装置について説明する。図3は、本発明の実施の形態2における液晶表示装置のRGB各画素の平面図である。図3における画素電極10は、複数の同心円がくり抜かれた形状で構成されている。
Claims (1)
- 画素の集合からなる表示画面を有する液晶表示装置であって、
1つの画素のそれぞれは、
n型液晶による液晶分子が傾くように制御された表示制御領域に複数の円周形状にくり抜かれた同心円構造を有するホールを複数個有する画素電極を備え、前記同心円構造は、中心から四方に連結線が設けられていることを特徴とする液晶表示装置。
