Cover window and display device having the same
A cover window covering a display panel of a display device comprises a base member covering a display area and a non-display area of the display panel, and an inorganic layer disposed on the base member. The inorganic layer has substantially uniform thickness on the display area, and has a diffraction grating structure on the non-display area.
1. A cover window covering a display panel of a display device, the cover window comprising:
a base member covering a display area and a non-display area of the display panel; and
an inorganic layer located on the base member, the inorganic layer having a substantially uniform thickness on the display area and having a diffraction grating structure on the non-display area,
wherein the diffraction grating structure comprises a plurality of grooves arranged in parallel in a first direction.
2. The cover window of claim 1 further comprising:
a coating layer located on the inorganic layer,
wherein the coating layer has substantially uniform thickness such that the coating layer has a substantially flat shape on the display area and has a diffraction grating structure corresponding to the diffraction grating structure of the inorganic layer in the non-display area.
3. The cover window of claim 2 , wherein the coating layer comprises an anti-fingerprint coating layer.
4. The cover window of claim 3 , wherein the anti-fingerprint layer comprises a fluorine-containing coating material.
5. The cover window of claim 1 , wherein the inorganic layer comprises silicon-oxide.
6. The cover window of claim 1 further comprising an anti-reflection layer located between the inorganic layer and the base member.
7. The cover window of claim 6 , wherein the anti-reflection layer comprises a plurality of layers having different refractive indexes.
8. The cover window of claim 7 , wherein the anti-reflection layer comprises a titanium oxide layer and a silicon oxide layer.
