Abstract:
1. A semiconductor device comprising: a plurality of pixels formed over a first substrate in a matrix form, each of the pixels comprising a pixel region having at least a pixel TFT and a transparent pixel electrode and a sensor portion having at least a sensor TFT and a photoelectric conversion element; a backlight; a pixel source signal line side driver circuit operationally connected to the pixel region; a pixel gate signal line side driver circuit operationally connected to the pixel region; a sensor horizontal driver circuit operationally connected to the sensor portion; a sensor vertical driver circuit operationally connected to the sensor portion; an insulating film formed over the pixel TFT and the sensor TFT; and a second substrate opposed to the first substrate with a liquid crystal disposed therebetween, wherein the photoelectric conversion element is formed over the insulating film and the transparent pixel electrode is formed over the photoelectric conversion element, wherein the first substrate is located between the back light and the liquid crystal.
