A display device includes: a display panel including a display region in which display pixels are two-dimensionally arranged, and a non-display region in which first dummy pixels and second dummy pixels are arranged; a first drive section allowing each of the first dummy pixels to emit light by applying signal voltages having different magnitudes to each of the first dummy pixels; a second drive section allowing each of the second dummy pixels to emit light by flowing constant currents having different magnitudes to each of the second dummy pixels; a current measurement section detection currents flowing through each of the first dummy pixels to output current information thereof; a light reception section detecting light emitted from each of the second dummy pixels to output luminance information thereof; and a calculation section deriving a current deterioration function using the current information, and deriving an efficiency deterioration function using the luminance information.
