    Abstract: A display device includes: an image display panel including pixels each including a first to a forth sub-pixel that display a first color to a fourth color; and a signal processing unit. The signal processing unit stores an expanded color space, determines maximum set brightness as an upper limit value of brightness displayable within a range of the brightness in the expanded color space so that the maximum set brightness increases as a panel average input value decreases, determines an input expansion coefficient for expanding the color displayed by the image display panel to a color of the maximum set brightness, obtains the output signal of the first to forth sub-pixel based on the input signal of the first to third sub-pixel and the input expansion coefficient. The expanded color space is a color space that can extend a color of brightness higher than that in a standard color space.

    Abstract: According to an aspect, a display device includes: a display unit; a lighting unit emitting internal light; a measurement unit; and a control unit controlling an intensity of the internal light and a gradation value of each pixel in the display unit. The control unit calculates a required luminance value for a luminance value of a pixel to be N times as high as a luminance value indicated by an input signal, the pixel performing output with the largest gradation value out of the pixels in a predetermined image display region. The control unit determines the intensity of the internal light based on an intensity of the external light measured by the measurement unit and the required luminance value, and calculates an output gradation value based on the gradation value indicated by input signal, the intensity of the external light, and the intensity of the internal light.
