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.

摘要： It is an object of the present invention to provide a display device equipped with a display panel that is provided with a photo-detection section with improved accuracy of detecting a touch position. A display panel (11) of an organic EL display device (10) includes a photo-detection section (40) that detects reflected light when a screen is touched by a finger or the like. The photo-detection section (40) includes a photodiode (41) that receives the reflected light, and an output amplifier (42) that outputs an output voltage corresponding to the amount of the received light. If an a-Si diode is used for such a photodiode (41), a sufficiently large signal difference in sensitivity between the bright state and the dark state can be achieved. Also, if a p-Si amplifier is used for the output amplifier (42), the output voltage becomes the saturation voltage at the time of read-out. This allows the p-Si amplifier to directly output the large sensitivity difference detected by the a-Si diode as a large difference in the output voltage.
