Abstract: A display panel may include a first hole, a second hole, a display element, a switching element, a wire, and a conductive member. The second hole may be spaced from the first hole. The switching element may be electrically connected to the display element. The wire may bypass the first hole in a plan view of the display panel and may be electrically connected to the switching element. The conductive member may surround each of the first hole and the second hole in the plan view of the display panel, may have an opening between the first hole and the second hole in the plan view of the display panel, and may partially cover the wire. An edge portion of the conductive member may intersect the wire and may be positioned between the display element and the first hole in the plan view of the display panel.

Abstract: A display device includes a substrate, a plurality of pixels, a plurality of wirings, a power voltage supply line, an insulating layer, and a window. The substrate includes a display area and a peripheral area outside the display area. The plurality of pixels are in the display area and the plurality of wirings are in the peripheral area. The power voltage supply line covers the plurality of wirings and includes a top surface having an irregular surface corresponding to the plurality of wirings. The insulating layer includes an opening overlapping a first portion of the power voltage supply line. The window is disposed on the insulating layer and includes a light-blocking region and a light-transmissive region, the light-transmissive region entirely covering the opening.

Abstract: A display apparatus that includes a substrate comprising a display area and a non-display area on a periphery of the display area. A display device is on the display area. The display device comprises a light-emitting device electrically connected to a thin film transistor. A first barrier wall is on the non-display area. The first barrier wall surrounds the display area and comprises a first layer and a second layer. The first layer comprises a first portion having a first height from an upper surface of the substrate, and a second portion having a second height from the upper surface of the substrate that is less than the first height. The second layer is on the second portion.
