1. A display device, comprising:
a display region in which a plurality of light emitting elements are arranged; a power supply unit provided outside the display region; a plurality of power supply lines connected to the power supply unit, for supplying power to the light emitting elements; a plurality of signal lines for supplying, when the plurality of power supply lines input a current to emit light from the light emitting elements, reference voltages that control light emission luminances of the light emitting elements; and a light emission control unit for individually outputting the reference voltages to the respective signal lines to display an image on the display region, based on information associated with a one-frame image, wherein the light emission control unit comprises:
correction voltage setting unit for discretely setting a predetermined number of steps of correction voltages; andreference voltage determining unit for selecting one of a predetermined number of steps of correction voltages set by the correction voltage setting unit, based on the information associated with the one-frame image, to determine the reference voltages of the respective signal lines, and wherein the plurality of signal lines are respectively connected to pixels which are configured to have the same light emission color as one another, wherein the correction voltage setting unit is configured to set an upper limit value and a lower limit value of the correction voltages based on information associated with the one-frame image, and the reference voltage determining unit is configured to individually select, for each of the plurality of signal lines, one of the predetermined steps of correction voltages that are discretely set in a range of the upper limit value and the lower limit value of the correction voltages.
