TWO-DIMENSIONAL SENSOR ARRAY, DISPLAY DEVICE, AND ELECTRONICS DEVICE

摘要

A display device according to the present invention includes a liquid crystal display panel in which a plurality of pixels are arranged in matrix, and an optical sensor circuit configured by a photodiode (17), a NetA voltage-boosting capacitor, and an output AMP. A driving wiring (Vrwn) for supplying a driving signal to the NetA voltage-boosting capacitor is electrically connected to a power supply wiring (Vsm) for supplying power to the output AMP. This configuration reduces parasitic capacitance resulting from an increase in the number of wirings. This makes it possible to make a display device having a pixel including an optical sensor incorporated therein, the display device capable of avoiding deterioration in sensor accuracy in the optical sensor circuit and preventing a decrease in the aperture ratio of the pixel.
