DISPLAY DEVICE AND ACTIVE MATRIX SUBSTRATE

摘要

A liquid crystal display device (11) of the present invention includes a liquid crystal layer (300) between a TFT array substrate (100) and a counter substrate (200). The TFT array substrate (100) has photo sensor elements (107) in pixels, and has transparent shield electrodes (108) which cover the photo sensor elements (107) provided. The transparent shield electrodes (108) are electrically insulated from pixel electrodes (106). Therefore, in the liquid crystal display device (11), an effect of electric noise on the photo sensor elements (107) can be reduced for avoiding deterioration of sensitivity of the photo sensor elements (107).
