Abstract
A method of manufacturing a cover window for a display device includes: providing a glass substrate having a bendable area and a flat area; modifying the bendable area by irradiating the glass substrate with a beam; and etching the bendable area to have a thinner thickness than the flat area. The bendable area may have a faster etch rate than the flat area due to the modifying of the bendable area.
