摘要： A liquid crystal display device 100 according to the present invention is provided with a liquid crystal panel 20 in which a liquid crystal layer 23 is disposed between an active matrix substrate 21 and an opposite substrate 22 and a backlight 10 that irradiates the liquid crystal panel 20 with light. The liquid crystal panel 20 has a plurality of optical sensor elements 30 that detect the intensity of received infrared light, and the backlight 10 has an infrared LED (light source) 12 that emits infrared light. On a device surface 100a, an infrared light transmissive sheet (infrared light partially transmissive portion) 50 that partially transmits infrared light is provided. The optical sensor elements 30 detect an input position from outside by detecting infrared light reflected from an inputting object such as a finger or the like placed on the device surface 100a. This way, an optical sensor integrated liquid crystal display device that can clearly distinguish whether or not an inputting object such as a finger or the like is touching the device surface can be achieved.

摘要： Provided is a display device that has a photodetection element in a pixel and can automatically correct a photosensor signal during operation, while resolving offset error with respect to the true black level or white level. As operation modes, a sensor row driver (5) has: (a) a sensor drive mode in which a sensor drive signal of a first pattern is supplied, and a photosensor signal that corresponds to the amount of light received by the photosensor is output to a signal processing circuit (8), and (b) a correction data acquisition mode in which a sensor drive signal of a second pattern that is different from the first pattern is supplied, and a correction photosensor signal level that corresponds to the case where the photosensor detected a black level or a white level is acquired. The photosensor signal levels obtained in the two modes while the ambient environment is controlled to a predetermined condition are stored in a memory. The signal processing circuit (8) corrects the photosensor signal in the sensor drive mode using the correction photosensor signal level that was corrected using the data for resolving offset.
