Abstract

A display device includes: a display panel having a display area and a non-display area; a light source configured to supply light to the display panel; a bottom chassis on which the light source is disposed; a top chassis coupled to the bottom chassis and not covering an edge portion of the display panel; and a mold unit coupled to the top chassis and covering the edge portion of the display panel, wherein the mold unit may be transparent.

First claim

What is claimed is:

1. A display device comprising:
a display panel having a display area and a non-display area;
a light source configured to supply light to the display panel;
a bottom chassis on which the light source is disposed;
a top chassis coupled to the bottom chassis; and
a mold unit coupled to the top chassis and covering the edge portion of the display panel, wherein the mold unit is transparent,
wherein the top chassis has:
a side wall coupled to the bottom chassis; and
a protrusion bent and extended from the side wall and disposed on the non-display area of the display panel.

2. The display device of claim 1 , wherein the mold unit is disposed on the non-display area and the display area.

3. The display device of claim 2 , further comprising a reflection tape disposed on a bottom surface of the mold unit overlapping the non-display area.

4. The display device of claim 1 , wherein the mold unit is coupled to the protrusion.

5. The display device of claim 4 , wherein the mold unit comprises:
a base unit disposed on the display area of the display panel; and
a coupling unit which protrudes and extends from one surface of the base unit and the protrusion is mounted on the coupling unit.

6. The display device of claim 5 , wherein the coupling unit has a smaller thickness than the base unit.

7. The display device of claim 5 , further comprising a locking protrusion bent and extended from the coupling unit and coupled to the side wall.

8. The display device of claim 4 , wherein the mold unit has a hole into which the protrusion is inserted.

9. The display device of claim 5 , wherein the display panel comprises a first substrate and a second substrate disposed to face the first substrate.

10. The display device of claim 9 , wherein an end portion of the second substrate is disposed on an area of the base unit.

11. The display device of claim 1 , wherein the top chassis is formed of a black material.

12. The display device of claim 1 , wherein the top chassis limits a position of the mold unit.

13. The display device of claim 1 , wherein the non-display area comprises a pad unit on which a driving chip is disposed.

14. A display device comprising:
a display panel having a display area and a non-display area;
a light source configured to supply light to the display panel;
a bottom chassis on which the light source is disposed;
a top chassis coupled to the bottom chassis, wherein the top chassis has:
a side wall coupled to the bottom chassis; and
a protrusion bent and extended from the side wall and disposed on the display area and the non-display area; and

a black printing layer disposed on one surface of the top chassis overlapping the non-display area, wherein the top chassis is transparent.

15. The display device of claim 14 , wherein the top chassis is disposed on the non-display area and the display area.

16. The display device of claim 14 , wherein the black printing layer is disposed on a bottom surface of the protrusion.

17. The display device of claim 14 , wherein the black printing layer is disposed on one surface of the protrusion and on one surface of the side wall.
