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.

The gate electrode, the source electrode and the drain electrode are connected to a cathode electrode (NetA) of the photodiode (17), a voltage supply wiring (Vsm) and an optical sensor output wiring (Vom), respectively. The NetA voltage raising capacitor has two electrodes. One of the two electrodes is electrically connected to the NetA, and the other of the two electrodes is electrically connected to a drive wiring (Vrwn) for supplying a drive signal to the NetA voltage raising capacitor. A storage capacitor wiring (Csn) for retaining a pixel potential also serves as the drive wiring (Vrwn). It is accordingly possible to attain a liquid crystal display device including the optical sensor circuits in which deterioration in aperture ratio of a pixel and increase in frame region surrounding a display section are suppressed.
