    • Provided is a display device that is capable of ensuring a wide dynamic range of an optical sensor even in the case where an offset due to ambient temperature changes is compensated with use of an output of a reference element. The display device has optical sensors in a pixel region of an active matrix substrate (100), wherein the optical sensors include a photodetecting sensor which outputs a sensor signal according to an amount of received light, and a reference sensor which has a configuration obtained by adding a light shielding film to the photodetecting sensor and outputs a sensor signal according to an offset component. The display device includes: an offset comparison circuit (61) that determines a degree of divergence between the sensor signal output from the reference sensor and a standard offset value; and a driving signal generation circuit (62) that adjusts a potential of a driving signal for the optical sensors according to the degree of divergence determined by the offset comparison circuit (61).
