LIQUID CRYSTAL DISPLAY DEVICE

摘要

A liquid crystal display device includes a plurality of pixels arranged in a matrix and constituted by first and second substrates and a liquid crystal layer held therebetween. The first substrate includes a common electrode arranged in common to the plurality of pixels, an insulating film arranged on the common electrode, a pixel electrode arranged facing the common electrode through the insulating film. Slits are formed in the pixel electrode. The liquid crystal layer is formed of a liquid crystal material having a voltage maintain rate larger than 90% in a period of 500 msec at temperature 60° C. and a rotational viscosity less than 90 mPa-s at temperature 25° C.
