Claim:
1. A display device, comprising: a display in which a plurality of pixels comprising a first pixel and a second pixel are arranged in a matrix shape; a source driver for applying a pixel voltage to the plurality of pixels through a plurality of signal lines; and a controller that controls the source driver based on a video signal input from outside, the first pixel and the second pixel each comprising a first sub-pixel, a second sub-pixel, and a third sub-pixel different from the first sub-pixel and the second sub-pixel, the first sub-pixel comprising: the second sub-pixel comprising: the third sub-pixel comprising: wherein: an area of the light exit portion included in the first sub-pixel of the first pixel is smaller than an area of the light exit portion included in the first sub-pixel of the second pixel; an area of the light exit portion included in the second sub-pixel of the first pixel is substantially equal to an area of the light exit portion included in the second sub-pixel of the second pixel; the controller converts, when the video signal input to the first sub-pixel of the first pixel is less than a predetermined value, the video signal input to the first sub-pixel of the first pixel into a video signal exhibiting a luminance higher than a luminance exhibited by the video signal input to the first sub-pixel; the source driver applies the pixel voltage to the first sub-pixel of the first pixel based on the video signal after conversion; and the controller converts, when the video signal input to the first sub-pixel of the first pixel after the conversion exceeds the predetermined value, the respective video signals input to the second sub-pixel and the third sub-pixel of the first pixel into respective video signals exhibiting luminances higher than luminances exhibited by the respective video signals input to the second sub-pixel and the third sub-pixel.
