Abstract: 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.

Abstract: 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.

Abstract: A method for manufacturing a display device includes preparing a target panel including a first substrate and a second substrate disposed on one surface of the first substrate, the target panel including a sealing area between the first substrate and the second substrate, making sealing light be incident in the sealing area and receiving at least a part of the sealing light reflected from the sealing area, generating first data including at least one parameter of intensity, energy, current, and voltage, and determining whether sealing is defective by comparing the first data and prestored second data.

Abstract: 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.
