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.

Abstract: A display device includes a display surface with pixels including four sub-pixels of four colors, and being arrayed in a matrix of a first viewing angle direction and a second viewing angle direction orthogonal thereto. The first viewing angle direction in a direction parallel to the display surface of a main viewing angle direction that intersects with the display surface. A reflective member, first substrate, a second substrate facing the first substrate, a color filter with filters of four colors corresponding to the four sub-pixels, and a scattering member is provided on the second substrate. For the color filter, a change in transmittance of the filters per pixel in the main viewing angle direction is smaller than a change in transmittance of the filters per pixel in a direction orthogonal to the first viewing angle direction in the second viewing angle direction parallel to the display surface.
