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.

Window for display apparatus, manufacturing method thereof, and manufacturing method of display apparatus

A device for inspecting a display device includes a camera to photograph a substrate and generate image information, a pixel value setter to set pixel values corresponding to respective luminances of a plurality of pixels from the image information, and to detect a crack region based on the pixel values, a stress calculator to calculate a critical stress of a crack included in the crack region, and a determiner to check whether the critical stress is equal to or greater than a first threshold value and to determine whether the substrate has defects. The stress calculator calculates a critical stress of the substrate by using fracture toughness, a shape factor, and a crack depth. The shape factor is set to increase as a compressive stress of the substrate increases.

Device for inspecting display device and inspecting method thereof

A glass member for a display device, a method of fabricating a glass member, and a display device including a glass member are provided. A method of fabricating a glass member for a display device includes: preparing a glass substrate including a first surface, a second surface facing the first surface, and a side surface connecting the first surface to the second surface; forming a protection layer on the side surface to cover a portion of the side surface; and etching a portion of the glass substrate exposed by the protection layer.
