DISPLAY DEVICE

摘要

Provided is a display device having an optical sensor wherein a photodiode (13) is arranged on an active matrix substrate (100). A readout signal wiring (RWS) which supplies the photodiode (13) with readout signals is connected to a light blocking layer (17) which limits light entering the photodiode (13). Thus, a capacitance (CINT) is formed between the photodiode (13) and the light blocking layer (17).
