Abstract: A display panel includes a display device layer including first to third light emitting areas and a non-tight emitting area and a light shielding member disposed on the display device laver. The light shielding member overlaps the non-light emitting area and includes light shielding openings corresponding to the first to third light emitting areas. A first portion of the light shielding member disposed between the first light emitting area and the second light emitting area has a first thickness at a first edge adjacent to the first light emitting area and a second thickness that is different from the first thickness at a second edge adjacent to the second light emitting area. A second portion of the light shielding member is disposed between the first light emitting area and the third light emitting area and has a uniform thickness.

Abstract: A manufacturing method of a display device includes preparing a substrate including a metal pattern, forming a first active pattern disposed on the substrate and including first and second areas and a first channel area between the first and second areas, forming a first gate electrode pattern on the first active pattern, forming a second active pattern on the first gate electrode pattern, forming an etch stop pattern overlapping the first and second areas, forming an inter-insulating layer covering the etch stop pattern, defining a first hole exposing the etch stop pattern and a second hole exposing the inter-insulating layer, defining a third hole exposing a top surface of the substrate, defining a fourth hole penetrating the etch stop pattern and a fifth hole exposing the metal pattern, forming a metal pattern connection electrode on the metal pattern, and forming a light-emitting device on the metal pattern connection electrode.
