发明名称 ACTIVE MATRIX LIQUID CRYSTAL DISPLAY DEVICE
摘要 PURPOSE: To solve problems inherent in a conventional liquid crystal panel of slow response speed, of high threshold voltage and of low luminance owing to reduced rotation of a liquid crystal in the vicinity of a CF(color filter) substrate compared with that in the vicinity of a TFT(thin film transistor) substrate due to nonuniformity of an electric field in the cell thickness direction. CONSTITUTION: By making a liquid crystal 220 on the side of a counter substrate 200 twist align in advance in such a way that an initial alignment angle of the liquid crystal 220 is made to deviate from an initial alignment angle of a liquid crystal 120 on the side of the TFT substrate 100, the liquid crystal 220 on the side of the counter substrate 200 is made to easily rotate when a lateral electric field is applied. Also accelerated response speed, lowered threshold voltage and heightened luminance are simultaneously accomplished with suppression of lowering of contrast by making the twist angle <= 2°.
