Display device having protective window
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.
1. A display device comprising:
a display panel including:
an image-generating panel, and
a protective window which is combined with the image-generating panel at a display surface of the image-generating panel, the protective window including:
a glass substrate having a thickness of about 20 micrometers to about 80 micrometers, and
a protective layer which faces the image-generating panel with the glass substrate therebetween to cover an edge portion of the glass substrate; and
a receiving member in which the display panel is received, the receiving member including a protruding portion which faces the edge portion of the glass substrate with the protective layer therebetween.
2. The display device of claim 1 , wherein the display panel further includes:
a protective film which faces the display surface of the image-generating panel with the glass substrate therebetween, and
an adhesive layer which is between the protective film and the glass substrate and combines the protective film with the glass substrate.
3. The display device of claim 2 , wherein at the edge portion of the glass substrate, a portion of the protective layer is between the protective film and the glass substrate.
4. The display device of claim 3 , wherein 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.
5. The display device of claim 3 , wherein at the edge portion of the glass substrate, the adhesive layer includes a side surface which faces a side surface of the protective layer.
6. The display device of claim 2 , wherein
the protective film includes an upper surface which is furthest from the glass substrate, and
at the edge portion of the glass substrate, the protruding portion of the receiving member faces the upper surface of the protective film.
7. The display device of claim 6 , wherein
the adhesive layer includes a side surface which faces a side surface of the protective layer, and
a thickness of the protective layer is greater than a thickness of the adhesive layer.
8. The display device of claim 2 , wherein an adhesion force between the protective layer and the adhesive layer is equal to or more than about 400 grams-force per inch.
9. The display device of claim 1 , wherein the protective layer includes a polymeric curable resin.
10. The display device of claim 1 , wherein the protective window further includes a light-blocking layer facing the protective layer with the glass substrate therebetween.
11. The display device of claim 10 , wherein the light-blocking layer and the protective layer include a same material.
