A display device may include: a substrate including a display area and a non-display area; and pixels disposed on the display area, and each including sub-pixels, each sub-pixel including a pixel circuit layer, and a display element layer including a light emitting element. The display element layer includes first and second electrodes spaced apart from each other; a first insulating layer disposed between the pixel circuit layer and the light emitting element; and a second insulating layer disposed on the light emitting element and filling spaces between the first insulating layer and ends of the light emitting element. The light emitting element includes a first conductive semiconductor layer, an active layer enclosing at least one side of the first conductive semiconductor layer, a second conductive semiconductor layer enclosing the active layer, an electrode layer enclosing the second conductive semiconductor layer, and an insulating film covering the electrode layer.
