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, wherein

the first sub-pixel, the second sub-pixel, and the third sub-pixel are inorganic light-emitting diodes, and

a light emission intensity of the third sub-pixel is decreased at a predetermined ratio with respect to a light emission intensity of the second sub-pixel when the second sub-pixel emits light at a light emission intensity within a low-luminance range equal to or lower than a predetermined level of luminance,

an input signal for the display device indicates a gradation value of the red, a gradation value of the green, and a gradation value of the blue, and

when the gradation values of other than green of the input signal are zero, a ratio of the gradation value of the blue to the gradation value of the green in an output signal is lower, as the gradation value of the green in the input signal is lower within the low-luminance range.
