    Abstract: An input device includes a first substrate, a first light-emitting element unit, and a third electrode unit. The first substrate has a first surface and a second surface. The first light-emitting element includes a first electrode unit formed on the second surface, a second electrode unit formed in a layer different from that of the first electrode unit, and a luminescent layer electrically in contact with at least a part of the first electrode unit and a part of the second electrode unit, and formed between the first electrode unit and the second electrode unit. The third electrode unit is insulated from the first electrode unit and detects a change in an electric field between the first electrode unit and the third electrode unit depending on coordinates of a proximity object present at a position overlapping with the first surface in planar view.

    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.
