Abstract

A display device includes a display panel configured to display an image. A base member is disposed on the display panel and includes a display area and a non-display area adjacent to the display area. The base member has a first surface facing the display panel. A first groove is formed on the first surface in the non-display area. A first light blocking member is disposed on the first surface of the base member and extends along at least a portion of the first surface positioned between the display area and the first groove.

Claims (55)

1 . A display device comprising:

a display panel configured to display an image;

a base member disposed on the display panel and including a display area and a non-display area adjacent to the display area, the base member having a first surface facing that is a closest surface of the base member to the display panel;

a first groove formed on the first surface in the non-display area; and

a first light blocking member disposed on the first surface of the base member and extending along at least a portion of the first surface positioned between the display area and the first groove, wherein the first light blocking member extends between the first surface and the display panel in a thickness direction of the display device.

2 . The display device of claim 1 , wherein:

the first light blocking member is disposed in the first groove; and

the first groove defines a boundary of the first light blocking member.

3 . The display device of claim 2 , wherein the first light blocking member fills the first groove.

4 . The display device of claim 1 , wherein the first light blocking member is disposed on the non-display area.

5 . The display device of claim 1 , wherein:

the non-display area is defined to surround the display area,

wherein the first groove is formed adjacent to an outer portion of the non-display area.

6 . The display device of claim 1 , wherein:

the display area includes at least one hole area;

at least one functional module overlaps the at least one hole area; and

the base member includes a second groove formed to surround the hole area.

7 . The display device of claim 6 , further comprising:

a second light blocking member disposed to surround the hole area and filling the second groove.

8 . The display device of claim 1 , wherein the non-display area of the base member is relatively flat.

9 . The display device of claim 1 , wherein the non-display area of the base member is curved toward the display panel.

10 . The display device of claim 1 , wherein the display area of the base member is relatively flat.

11 . The display device of claim 1 , wherein:

the base member further comprises a second surface opposing the first surface and a side surface connecting the first surface and the second surface,

wherein the side surface adjacent to the first surface is a chamfered surface that is inclined.

12 . The display device of claim 11 , wherein the first groove is formed between the chamfered surface and the display area.

13 . The display device of claim 11 , wherein the side surface adjacent to the second surface is a round surface.

14 . The display device of claim 1 , wherein the first groove is formed using a laser.

15 . The display device of claim 1 , wherein the display panel comprises:

a substrate;

at least one thin film transistor disposed on the substrate; and

a light emitting diode electrically connected to the at least one thin film transistor.

16 . The display device of claim 15 , wherein the light emitting diode comprises:

a first electrode connected to the thin film transistor;

an organic emission layer disposed on the first electrode; and

a second electrode disposed on the organic emission layer.

17 . A display device comprising:

a display panel configured to display an image;

a base member disposed on the display panel and including a display area and a non-display area adjacent to the display area, the base member having a first surface facing that is a closest surface of the base member to the display panel and a chamfered surface adjacent to the first surface and inclined,

a first groove formed on the first surface in the non-display area; and

a first light blocking member disposed on the first surface of the base member and extending along at least a portion of the first surface between the display area and the first groove, wherein the first light blocking member extends between the first surface and the display panel in a thickness direction of the display device.

18 . The display device of claim 17 , wherein the first light blocking member fills the first groove.

19 . The display device of claim 17 , wherein:

the non-display area is defined to surround the display area,

wherein the first groove is formed adjacent to an outer portion of the non-display area.

20 . The display device of claim 17 , wherein:

the display area includes at least one hole area;

at least one functional module overlaps the at least one hole area; and

the base member includes a second groove formed to surround the hole area.

21 . A display device comprising:

a display panel configured to display an image;

a base member disposed on the display panel and including a display area and a non-display area adjacent to the display area, the base member having a first surface facing that is a closest surface of the base member to the display panel;

a first groove formed on the first surface in the non-display area, the first groove having a semi-elliptical shape in a cross-section; and

a first light blocking member disposed in the first groove and extending along at least a portion of the non-display area, wherein the first light blocking member extends between the first surface and the display panel in a thickness direction of the display device.

22 . The display device of claim 21 , wherein the first groove defines an outer boundary of the first light blocking member.
