摘要： An IPS liquid crystal display device having comb-teeth-shaped pixel electrodes which can prevent image retention while ensuring reliability of through hole portions and reliability of terminal area is provided. In an IPS liquid crystal display device having comb-teeth-shaped pixel electrodes, image retention occurs when rubbing is not applied to a gap defined between the comb-teeth-shaped electrodes. The pixel electrodes, through holes which supply a voltage to the pixel electrodes and a terminal area are formed of an ITO film. By setting a film thickness of only the ITO film for forming the pixel electrodes smaller than a film thickness of the ITO film formed at the through holes and a film thickness of the ITO film for forming the terminal area, it is possible to sufficiently apply rubbing to a gap between the comb-teeth-shaped electrodes which constitute the pixel electrodes.
