Abstract

A display device includes: a backlight unit, a camera hole penetrating the backlight unit, a camera in the camera hole, a liquid crystal panel on the backlight unit, the liquid crystal panel including a transparent portion on the camera hole, and at least one light-blocking member in the camera hole, the at least one light-blocking member being configured to reduce one or more of: light leakage from the camera hole and introduction of impurities into the camera hole.

Claims (45)

1. A display device, comprising:

a backlight unit;

a liquid crystal panel on the backlight unit;

a camera hole penetrating the backlight unit and the liquid crystal panel;

a camera in the camera hole; and

a light-blocking member covering a portion of the camera hole located between the camera and the liquid crystal panel,

wherein the light-blocking member is attached to:

an upper surface of the liquid crystal panel, and

an upper surface of the camera.

2. The display device of claim 1 , wherein the camera extends in the camera hole up to the upper surface of the liquid crystal panel.

3. The display device of claim 1 , wherein the light-blocking member comprises a light-blocking tape.

4. The display device of claim 1 , wherein:

the camera hole has a circular cross-section; and

the light-blocking member is shaped as a circular ring that is concentric with a circumferential surface of the camera hole.

5. The display device of claim 1 , wherein a color of the light-blocking member is black.

6. The display device of claim 1 , further comprising:

a side surface connection portion connecting the bottom-coupling portion to the upper support portion.

8. The display device of claim 7 , wherein the bottom-coupling portion is coupled to a side surface of the cover bottom.

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

a lower polarizing plate between the backlight unit and the liquid crystal panel, the camera hole penetrating the lower polarizing plate; and

an upper polarizing plate on the liquid crystal panel,

wherein the camera hole penetrates the upper polarizing plate.

10. The display device of claim 6 , wherein the light-blocking member is attached to an upper surface of the insert mold.

11. The display device of claim 10 , the insert mold is integrated into the cover bottom.

12. A display device, comprising:

a backlight unit;

a liquid crystal panel on the backlight unit;

a camera hole penetrating the backlight unit and the liquid crystal panel;

a camera in the camera hole;

an insert mold; and
