Display device

A display device performing brightness control of a backlight and gradation conversion of an image, comprising:

• a display panel including a plurality of pixel circuits;
• a drive circuit that drives the display panel;
• a backlight that irradiates a back side of the display panel with light;
• a gradation conversion unit that performs gradation conversion on an input image, by applying a predetermined gain to a gradation smaller than a boundary gradation and applying, to a gradation larger than the boundary gradation, a gain which decreases as the gradation increases, and that outputs a converted image to the drive circuit;
• and
• an image analysis unit that analyzes the input image and determines a characteristic of the gradation conversion unit and brightness of the backlight,
• wherein the image analysis unit obtains the boundary gradation and the maximum gradation included in the input image based on the input image and, based on the obtained two gradations, determines a characteristic of the gradation conversion unit so that brightness decreasing rate of the maximum gradation when the brightness control of the backlight is performed becomes a limit value or less.
