Abstract: A display device may include: a substrate; a light emitting element on the substrate; a first pixel electrode on one area of the light emitting element and is electrically connected to the light emitting element; and a second pixel electrode on an other area of the light emitting element and is electrically connected to the light emitting element. The light emitting element may include: a first semiconductor layer, an active layer, and second and third semiconductor layers sequentially arranged along a first direction; and an insulative film covering outer surfaces of the first semiconductor layer, the active layer, and the second and third semiconductor layers. An opening exposing at least one side surface of the second semiconductor layer to the outside while penetrating the insulative film. The second pixel electrode may be in contact with the second semiconductor layer.

Abstract: A method for manufacturing a display device is provided. The method includes: placing a light emitting element on a substrate including cell areas; placing an insulating layer on the light emitting element; and separating the cell areas from each other. Light emitting panels are located on the substrate, correspond to each of the cell areas, and include the light emitting element. The separating of the cell areas from each other includes electrically separating the light emitting panels from each other. The electrically separating the light emitting panels from each other is performed after the placing of the insulating layer.
