Abstract

A display device including a housing including sidewalls and mounting surfaces at upper ends of the sidewalls; a display panel housed in the housing; and a cover window on the display panel, wherein the cover window includes an upper surface that faces outwardly in a direction in which light is emitted, a lower surface opposite to the upper surface, the lower surface being narrower than the upper surface, and side surfaces that slope inwardly from ends of the upper surface to ends of the lower surface, the side surfaces being at least partially bent, and wherein the side surfaces of the cover window are mounted on the mounting surfaces of the housing.

First claim

What is claimed is:

1. A display device, comprising:
a housing including sidewalls and mounting surfaces at upper ends of the sidewalls;
a display panel housed in the housing; and
a cover window on the display panel,
wherein the cover window includes:
a flat upper surface that faces outwardly in a direction in which light is emitted,
a flat lower surface opposite to the upper surface, the lower surface being parallel with and narrower than the upper surface,
curved side surfaces that slope inwardly from ends of the flat upper surface to ends of the flat lower surface, and
a printing layer disposed between the curved side surfaces and the mounting surfaces,

wherein the curved side surfaces of the cover window are mounted on the mounting surfaces of the housing, and
wherein the mounting surfaces have a shape corresponding to that of the curved side surfaces and are disposed on a non-display area.

2. The display device as claimed in claim 1 , further comprising a polarizing plate between the display panel and the cover window.

3. The display device as claimed in claim 1 , wherein a thickness of the cover window increases from an outer side thereof toward an interior thereof.

4. The display device as claimed in claim 1 , wherein a radius of curvature of each of the curved side surfaces reduces from an outer side thereof toward an interior of the cover window.

5. The display device as claimed in claim 1 , further comprising a first adhesive layer between the cover window and the display panel.

6. The display device as claimed in claim 5 , wherein the first adhesive layer includes an optically clear adhesive.

7. The display device as claimed in claim 1 , further comprising a cushion member between a lower surface of the display panel and an inner surface of the housing.

8. The display device as claimed in claim 1 , wherein the mounting surfaces complement the curved side surfaces.

9. The display device as claimed in claim 1 , further comprising a second adhesive layer between the mounting surfaces and the curved side surfaces.
