Abstract: A display apparatus includes a display panel including pixels and a cover window disposed on the display panel. The cover window includes a flat portion having a first thickness, and a folding portion having a second thickness that is less than the first thickness of the flat portion, the folding portion being adjacent to the flat portion. A first stress profile of the flat portion of the cover window that is a stress change along a depth direction from a surface of the flat portion of the cover window is different from a second stress profile of the folding portion of the cover window that is a stress change along a depth direction from a surface of the folding portion of the cover window.

CPC classification number: B24B7/10
Abstract: A method of manufacturing a window for a display apparatus according to the present invention includes: providing, on a stage, a substrate including a foldable part bending around a folding axis extending in a first direction, and forming a groove on the foldable part. The forming the groove includes: grinding the foldable part by using a first machining wheel; grinding the foldable part by using a second machining wheel; and machining the foldable part by using a polishing wheel. The groove has at least one radius of curvature. The first machining wheel includes first abrasive grains, and the second machining wheel includes second abrasive grains less in size than the first abrasive grains.
