    • Provided is a display device with a photosensor having little variation between sensors. The display device includes a photosensor in a pixel region of an active matrix substrate. The photosensor includes a photodetection element (M4) that receives incident light, a capacitor (C1), one electrode of which is connected to the photodetection element (M4), that accumulates output current from the photodetection element, reset signal wiring (RST) that supplies a reset signal to the photosensor, readout signal wiring (RWS) that supplies a readout signal to the photosensor, and a sensor switching element (M2) that, in accordance with the readout signal, reads out the output current accumulated in the capacitor (C1) from when the reset signal is supplied until when the readout signal is supplied. A phototransistor is used as the photodetection element (M4).
    • 提供一种具有光传感器的显示装置,其在传感器之间具有很小的变化。 显示装置包括在有源矩阵基板的像素区域中的光电传感器。 光传感器包括接收入射光的光检测元件(M4),其一个电极连接到光电检测元件(M4)的电容器(C1),其累积来自光电检测元件的输出电流,复位信号布线(RST) 向光电传感器提供复位信号,向光传感器提供读出信号的读出信号布线(RWS)以及根据读出信号读出在电容器中累积的输出电流的传感器开关元件(M2) C1)从提供复位信号直到提供读出信号时。 光电晶体管用作光电检测元件(M4)。
