发明名称 IPS liquid crystal display device with edge of the pixel electrode, common electrode, and signal line having stairwise stepped portions
摘要 In an IPS liquid crystal display device, a reduction in optical leakage from the outer peripheral portion of an electrode pattern in flexed configuration and an improvement in the contrast of display on a screen are intended. The IPS liquid crystal display device has a plurality of signal lines and scan lines arranged as a matrix on a TFT substrate, TFT switching elements, and comb-like pixel electrodes connected to the TFT switching elements. In a pixel region, a comb-like common electrode is formed in interdigitated relation with the pixel electrodes. The pixel electrodes, the common electrode, and the signal lines are formed in mutually parallel and flexed configuration at a given angle relative to an optical axis. The outer edge of each pixel electrode, the common electrode, and the signal lines is added with fine stairwise fine stepped portions composed of the same material as composing the electrodes and lines.
