摘要： A display device includes a display module having a display region and a non-display region, and a window module disposed on the display module. The window module includes a thin glass substrate, a window protective layer disposed on the thin glass substrate, and a bezel pattern disposed on a surface of the thin glass substrate or disposed on a surface of the window protective layer. The bezel pattern overlaps the non-display region. The edge of the thin glass substrate does not overlap the bezel pattern in a plan view, and the edge of the thin glass substrate is not aligned with the outer edge of the bezel pattern in a plan view.

摘要： A protective window includes a glass substrate which faces a display surface of an image-generating panel and has a thickness of about 20 micrometers to about 80 micrometers; a protective film which faces the display surface of the image-generating panel with the glass substrate therebetween; an adhesive layer which is between the protective film and the glass substrate and combines the protective film with the glass substrate; and a protective layer which covers an edge portion of the glass substrate. A thickness of the protective layer which covers the edge portion of the glass substrate is equal to or less than about ⅓ of a thickness of the adhesive layer which combines the protective film with the glass substrate.
