A display panel includes a substrate having an opening area, and a display area at least partially surrounding the opening area. Display elements are arranged in the display area. The display elements includes a pixel electrode, an opposite electrode, and an intermediate layer interposed therebetween. A multilayer film includes a first insulating layer between the substrate and the pixel electrode and a second insulating layer, of a different material, on the first insulating layer. A thin film encapsulation layer covers the display elements and includes at least one organic encapsulation layer and at least one inorganic encapsulation layer. The multilayer film includes a first groove disposed between the opening area and the display area. The first groove has an undercut structure in which a lower width of the first groove is greater than an upper width of the first groove.

Display panel and display device including display panel

A display panel including a glass substrate having an opening area, and a display area at least partially surrounding the opening area; a thin film transistor on the display area including a semiconductor layer and a gate electrode; a display element electrically connected to the thin film transistor; a multi-layer including an insulating layer and a lower insulating layer. The insulating layer is between the glass substrate and the display element and the lower insulating layer is between the glass substrate and the insulating layer; and a thin-film encapsulation layer covering the display element including an inorganic encapsulation layer and an organic encapsulation layer. The multi-layer includes a first groove between the opening area and the display area. A first width of a portion of the first groove in the lower insulating layer is greater than a second width of a portion of the first groove in the insulating layer.

Display panel, and display device including the same

A display panel includes a base layer, a signal line which is disposed on the base layer and includes a first layer including aluminum and a second layer disposed directly on the first layer and consisting of niobium, a first thin film transistor connected to the signal line, a second thin film transistor disposed on the base layer, a capacitor electrically connected to the second thin film transistor, and a light emitting element electrically connected to the second thin film transistor.

Display panel including a signal line having a two-layer structure, and method for manufacturing the same

Disclosed are display panels and methods of manufacturing substrates. The display panel comprises a lower display substrate that includes a plurality of light emitting elements, and an upper display substrate that includes a color control layer and is on the lower display substrate. The color control layer includes a plurality of walls each of which includes a wall base including an organic material and a reflective layer including a metallic material, and the color control layer also includes a plurality of color control parts which are disposed between the plurality of walls and at least one of which includes a quantum dot. The reflective layer surrounds at least a portion of a sidewall of the wall base, which results in an increase in luminous efficiency and an improvement in brightness.
