Abstract: 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.
