Abstract

A display apparatus includes a display panel and a mold frame. The display panel includes a display area, a peripheral area surrounding the display area, an alignment mark on the peripheral area, and a cover element overlapping the alignment mark to cover the alignment mark. The mold frame has a frame shape configured to receive the display panel. The mold frame includes a panel guide protrusion protruding from an inner surface of the mold frame, and the panel guide protrusion is adjacent to the alignment mark.

First claim

What is claimed is:

1. A display apparatus, comprising:
a display panel comprising:
a display area, and a peripheral area surrounding the display area,
an alignment mark on the peripheral area; and
a cover element overlapping the alignment mark to cover the alignment mark; and

a mold frame having a frame shape and configured to receive the display panel,
the mold frame comprising a panel guide protrusion which protrudes from an inner surface of the mold frame and is adjacent to the alignment mark.

2. The display apparatus of claim 1 , wherein colors of the alignment mark and the mold frame are different from each other.

3. The display apparatus of claim 2 , wherein the color of the alignment mark is black.

4. The display apparatus of claim 3 , wherein the alignment mark comprises carbon black.

5. The display apparatus of claim 2 , wherein the color of the mold frame is white.

6. The display apparatus of claim 5 , wherein the mold frame comprises polycarbonate.

7. The display apparatus of claim 1 , wherein
the display panel further comprises a first substrate, and a second substrate facing the first substrate, and
the alignment mark is on the first substrate.

8. The display apparatus of claim 1 , wherein the alignment mark has a quadrangle shape having a width of about 2 millimeters to about 4 millimeters, and a length of about 1 millimeter to about 3 millimeters.

9. The display apparatus of claim 1 , wherein the panel guide protrusion has a quadrangle shape having a width of about 4 millimeters to about 6 millimeters and a length of about 1 millimeter to about 3 millimeters.

10. The display apparatus of claim 1 , wherein
in a plan view, the display panel further comprises first and second sides facing each other, and third and fourth sides facing each other and perpendicular to the first and second sides, and
the alignment mark is on the first to fourth sides of the display panel.

11. The display apparatus of claim 1 , further comprising a light source unit configured to generate light.

12. The display apparatus of claim 11 , wherein the light source unit comprises:
a light source generating the light, and
a light guide plate configured to guide the light to the display panel.

13. A method of manufacturing a display apparatus, comprising:
providing an alignment mark on a peripheral area of a display panel, the display panel comprising a display area, and the peripheral area surrounding the display area;
combining the display panel with a mold frame having a frame shape, to receive the display panel in the mold frame; and
providing a cover element on the display panel to cover the alignment mark,
wherein the mold frame comprises a panel guide protrusion which protrudes from an inner surface of the mold frame and is adjacent to the alignment mark.

14. The method of claim 13 , wherein colors of the alignment mark and the mold frame are different from each other.

15. The method of claim 14 , wherein the color of the alignment mark is black.

16. The method of claim 14 , wherein the alignment mark comprises carbon black.

17. The method of claim 14 , wherein the color of the mold frame is white.

18. The method of claim 17 , wherein the mold frame comprises polycarbonate.

19. The method of claim 13 , wherein
the display panel further comprises a first substrate, and a second substrate facing the first substrate, and
the alignment mark is on the first substrate.

20. The method of claim 13 , wherein
in a plan view, the display panel further comprises first and second sides facing each other, and third and fourth sides facing each other and perpendicular to the first and second sides, and
the alignment mark is on first to fourth sides of the display panel.
