Abstract: A display device is disclosed that includes a base layer, a light-emitting element, and a pixel circuit. The pixel circuit includes a first transistor, and the first transistor includes a metal oxide semiconductor pattern, a first gate having a plurality of conductive layers, and a gate insulation pattern. The uppermost layer among the plurality of conductive layers is divided into a first part adjacent to a drain region, a second part adjacent to a source region, and a third part between the first part and the second part. An upper surface of each of the first part and the second part may form a step with an upper surface of the third part. A sum of the widths of the upper surfaces of the first part and the second part may be smaller than the width of the upper surface of the third part.

Abstract: 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.

Abstract: 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.
