Abstract: In order to increase the transmittance around a pixel and to increase the brightness of the screen in an IPS mode liquid crystal display device, a pixel electrode with a slit is formed on a common electrode through an interlayer insulating film. An opening is formed in the common electrode on the outside of the end portion of the pixel electrode as seen in a plane view. Because of the presence of the opening, the electric field lines from the end portion of the pixel electrode reach the layer above the liquid crystal layer and reach further away from the end portion of the pixel electrode, so that it is possible to increase the control ability to the liquid crystal around the pixel. As a result, the pixel transmittance can be increased as a whole and the brightness of the screen can be increased.

Abstract translation: 为了在IPS模式液晶显示装置中增加像素周围的透射率并增加屏幕的亮度，通过层间绝缘膜在公共电极上形成具有狭缝的像素电极。 在平面图中看到，像素电极的端部的外侧的公共电极上形成开口。 由于存在开口，所以来自像素电极的端部的电场线到达液晶层上方的层并且进一步远离像素电极的端部，从而可以增加控制 像素周围的液晶的能力。 结果，可以提高像素的透射率，并且可以提高屏幕的亮度。
