Abstract:
A light shield (204) for blocking light traveling toward a PIN photodiode (413) from a glass substrate (314) side is formed of a conductive material, and a reference electric potential (Vr−nVoc) equal to that of a cathode of the PIN photodiode (413) is applied to the light shield (204) from a power supply circuit (266). Thus, inductive noise for a photoelectric conversion device used for an ambient light sensor is further reduced in a display device.
