Abstract: According to an aspect, a display device includes an image display unit in which pixels each including a plurality of sub-pixels are arranged in a matrix, and a color converting unit that performs color conversion to reduce power consumption in the image display unit. The color converting unit does not perform the color conversion when total power consumption obtained by adding up the power consumption in the image display unit and power consumption in the color converting unit in a case where the color conversion is performed exceeds the power consumption in the image display unit in a case where the color conversion is not performed.
