Abstract: Screen brightness is improved in an IPS type liquid crystal display device.A common electrode having a slit is disposed over a rectangular pixel electrode with an insulating film attached therebetween. The slit has a linear part and a bend part. The bend part is necessary for preventing pressing domain. The transmittance in the bend part is increased by making the thickness of the insulating film below the bend part of the slit to less than the thickness of the insulating film at the linear part of the slit, thereby increasing the transmittance of the entire pixel. Thus, the screen brightness can be improved.

Abstract translation: IPS型液晶显示装置的屏幕亮度得到改善。 具有狭缝的公共电极设置在矩形像素电极上，其间具有绝缘膜。 狭缝具有直线部分和弯曲部分。 弯曲部分是防止按压区域所必需的。 通过使狭缝的弯曲部下方的绝缘膜的厚度小于狭缝的直线部分处的绝缘膜的厚度，从而提高了整个像素的透射率，从而增加弯曲部的透射率。 因此，可以提高屏幕亮度。
