LIQUID CRYSTAL DISPLAY DEVICE AND A METHOD OF MANUFACTURING THE SAME

摘要

A liquid crystal display device and a method of manufacturing the same are provided to improve light sensitivity of a light receiving device and suppress a dark current. A TFT(Thin Film Transistor) array substrate(201) includes a glass substrate. A pixel switching element(31) is formed in a display area(TA) of a pixel area(PA). A light receiving element(32) is formed in a sensor area(SA) of the pixel area. A peripheral circuit element(SK) is formed in a peripheral area(CA). A planarization film(60a) is formed on a surface of the glass substrate. An insulation film(60b) coats a common electrode in an area corresponding to the display area.
