Abstract: According to an aspect, a display device includes: a controller; and a pixel including: first to fourth sub-pixels including respective first to fourth color filters transmitting light having respective spectrum peaks falling on a spectrum of reddish green, a spectrum of bluish green, a spectrum of red, and a spectrum of blue, respectively. The first to fourth sub-pixels each include a reflective electrode reflecting light transmitted through the color filter. The first to fourth sub-pixels are each divided into sub-divided pixels having different areas to perform multiple gradation expression through a combination of whether each of the sub-divided pixels reflects light. The controller stores patterns of combinations of whether each of the sub-divided pixels reflects light according to an input signal, and controls operations of the sub-divided pixels through use of any one of the patterns based on a predetermined condition including light intensity.
