A display device includes a hole transport layer common to a plurality of light-emitting elements between a light-emitting layer and an anode electrode below thereof in the light-emitting element in each pixel. The hole transport layer includes a hole transport section that transports positive holes to the light-emitting layer, and an adjacent pixel hole blocking section that is formed in a portion between the light-emitting elements in adjacent pixels and blocks transportation of positive holes between the light-emitting elements in adjacent pixels.

Display device having carrier blocking section between pixels

A display device includes: a display unit at least partially foldable and transformable, and including a display surface that displays an image; a body unit provided to a back face of the display unit; and a sensor having a detecting surface positioned to be covered with the display unit or the body unit. The display device is switchable between a covering state in which the detecting surface is covered and an uncovering state in which the detecting surface is uncovered. The uncovering state is switched from the covering state by folding transformation of the display unit.
