Abstract: A display device may include: a substrate including a display area and a non-display area; and at least one pixel disposed in the display area, and comprising at least one pixel including an emission area that emits light. The at least one pixel may include: at least one sub-electrode extending in a direction on the substrate; at least one branch electrode extending in a direction and spaced apart from the sub-electrode; a first insulating layer disposed on the at least one sub-electrode and the at least one branch electrode; first electrodes disposed on the first insulating layer and electrically connected with the at least one sub-electrode; second electrodes disposed on the first insulating layer and electrically connected with the at least one branch electrode; and at least one light emitting element aligned between at least one of the first electrodes and at least one of the second electrodes.

Abstract: A method for manufacturing a display device including a substrate including a display area and a non-display area located outside the display area, the display area including pixel areas, is provided. First switching elements are formed in the pixel areas, respectively, and a circuit element layer that includes reference voltage wire in the non-display area and electrically connected to the first switching elements is formed. Pixel electrodes that include first pixel electrodes in the pixel areas on the circuit element layer, respectively, and electrically connected through the first switching elements to the reference voltage wire, and second pixel electrodes facing the first pixel electrodes, are formed. A plurality of light emitting elements are arranged between the first pixel electrodes and the second pixel electrodes. A first source voltage is applied to the reference voltage wire and a second source voltage is applied to the second pixel electrodes.
