Abstract
A display device includes an electroluminescent panel including first light-emitting elements to emit red (first color), second light-emitting elements to emit green (second color), and third light-emitting elements to emit blue (third color); an image analyzer that obtains, in displaying of a received video signal, first power serving as a total of power required for displaying red (first color), power required for displaying green (second color), and power required for displaying blue (third color), and that calculates second power by multiplying the first power by a predetermined coefficient according to the video signal, and calculates threshold power by multiplying, by the coefficient, maximum allowable power that is allowed when the electroluminescent panel performs image display; and a luminance adjuster that multiplies the video signal by a ratio between the threshold power and the second power when the second power is equal to or greater than the threshold power.
