Abstract: An input device includes a first substrate, a light-emitting element unit, and third conductive layers. The first substrate includes first and second surfaces. The light-emitting element unit includes: first conductive layers formed in one layer on the second surface side; second conductive layers formed in one layer on the second surface side different from the layer of the first conductive layers; and a luminescent layer provided between the first and the second conductive layers and electrically in contact therewith. The third conductive layers are formed to be insulated from the first and the second conductive layers and not to intersect with the second conductive layers in planar view, and are configured to detect a change in an electric field between the first and the third conductive layers depending on coordinates of a proximity object at a position overlapping with the first conductive layers and the first surface in planar view.

Abstract: According to an aspect, a display device includes a plurality of pixels each including a plurality of sub-pixels. Each of the sub-pixels is arranged around center of the corresponding pixel and divided into a plurality of display regions to perform N-bit area coverage modulation by a combination of the display regions. The display regions are arranged in such a manner that: a display region corresponding to a least significant bit of the area coverage modulation is arranged closest to the center of the corresponding pixel; and a display region corresponding to a higher significant bit of the area coverage modulation is arranged around the center of the pixel and further from the center of the corresponding pixel (N is a natural number of 2 or more).
