摘要： A display device includes a first non-folding area and a second non-folding area, a display panel disposed in the first non-folding area and the second non-folding area, a leveling layer on the display panel in the first non-folding area, a protection window on the leveling layer in the first non-folding area, and a transmission control layer on the display panel in the second non-folding area. A thickness of the transmission control layer is substantially equal to a sum of a thickness of the leveling layer and a thickness of the protection window.

摘要： A method for manufacturing a display device includes forming a plurality of light blocking patterns on a first surface of a transparent substrate, wherein a first light blocking pattern of the plurality of light blocking patterns has a different line width than a second light blocking pattern of the plurality of light blocking patterns. An insulating layer is formed on the first surface of the transparent substrate and the light blocking patterns. A conductive layer is formed on the insulating layer. A photo-resist layer is formed on the conductive layer. The photo-resist layer is exposed with ultraviolet rays through a second surface of the transparent substrate, wherein the first and second surfaces of the transparent substrate are opposite to each other. The photo-resist layer is developed. The conductive layer is etched using the photo-resist layer as a mask. The photo-resist layer is removed.

摘要： A method for inspecting a display device includes preparing a target substrate comprising sub-pixels in which light-emitting elements are disposed, dividing each of first regions of the sub-pixels into second regions, obtaining a gray value of each of the second regions, generating a random number using the gray value, calculating a representative value of each of the first regions by reflecting variables in the random number, and summing the representative values of the first regions to calculate a number of light-emitting elements of the sub-pixels.
