LIQUID CRYSTAL DISPLAY DEVICE

摘要

A pixel electrode formed into a slit structure with striped electrodes opposed to each other for a zero rubbing angle can provide fast response since rotational directions of the liquid crystals become opposite at both sides of the slit in the striped electrodes. The electrode structure, however, poses a problem of low transmittance.;Provided is a liquid crystal display device of IPS-Pro scheme including a pixel electrode with one pair of striped electrodes. The first striped electrode includes a short electrode section and long electrode sections, and the second striped electrode also includes a short electrode section and long electrode sections. The long electrode sections of the first striped electrode are disposed adjacently to those of the second striped electrode. Liquid crystals are aligned in a lengthwise direction of the striped electrodes.
