    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.

    Abstract: An input device includes a first substrate, a light-emitting element, and a third electrode unit. The first substrate has first and second surfaces. The light-emitting element unit includes: a first conductive electrode unit including first conductive layers; a second conductive electrode unit including second conductive layers each having a size overlapping with the first conductive layer in planar view; and luminescent layers conducted with at least a part of the first electrode unit, each provided between the first and second electrode units and conducted with the first conductive layer and the second conductive layer overlapping with the first conductive layer in planar view. The third electrode unit is insulated from the first conductive layers and detects a change in an electric field between the first conductive layers and the third electrode unit depending on coordinates of a proximity object at a position overlapping with the first surface in planar view.
