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.
