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.
