Abstract: A manufacturing method of a mask assembly includes forming a cell mask including masking patterns and a mesh frame including conductive patterns disposed to correspond to the masking patters and disposing the cell mask and the mesh frame on a mask frame. The forming the cell mask and the mesh frame includes forming a polymer layer, a conductive layer, and a hard masking layer, forming a mask pattern layer including etch patterns, and forming the cell mask and the mesh frame using the mask pattern layer.

Abstract: A display device includes a substrate including first, second, and third light emitting areas and a light blocking area surrounding the first, second, and third light emitting areas, a driving element on the substrate, a light emitting element respectively in each of the first, second, and third light emitting areas on the driving element and electrically connected to the driving element, a color conversion layer including a first color conversion pattern, a second color conversion pattern, and a transmission pattern in the first, second, and third light emitting areas on the light emitting element, respectively, and a capping layer on the color conversion layer and including a silicon compound. A ratio of a hydrogen content of an N—H bond to a hydrogen content of a Si—H bond of the capping layer is about 16 or more.
