Abstract: According to an aspect, a display device includes a pixel including a first sub-pixel configured to emit light having a peak in a spectrum of red, a second sub-pixel configured to emit light having a peak in a spectrum of green, and a third sub-pixel configured to emit light having a peak in a spectrum of blue. The first sub-pixel, the second sub-pixel, and the third sub-pixel are inorganic light-emitting diodes. A light emission intensity of the second sub-pixel is increased at a predetermined ratio with respect to a light emission intensity of the first sub-pixel when the first sub-pixel emits light at a light emission intensity within a low-luminance range equal to or lower than a predetermined level of luminance.
