A display device includes a housing, a display panel, a light source, a first acquirer, a second acquirer, and a stabilizer. The display panel is provided in the housing. The light source is provided in the housing, and includes an LED that irradiates the display panel with light. The first acquirer acquires a first temperature in a first region including a region where the light source is disposed in the housing. The second acquirer acquires a second temperature in a second region different from the first region. The stabilizer has a first adjustment mode for lighting the LED with maximum luminance as an adjustment mode for stabilizing luminance of the LED. The stabilizer operates the LED in the first adjustment mode in a case where a temperature difference between the first temperature and the second temperature is a first threshold value or more.
