Abstract

A display device is disclosed. The display device includes a display panel, a frame positioned behind the display panel, a plate positioned between the display panel and the frame, and a side frame, which extends along an edge of the frame behind the frame and which is coupled to the frame, wherein the plate includes a base facing the frame, and a projection, which projects rearwards from the base through the frame and the side frame and which is bent at an end thereof so as to be coupled to the side frame.

First claim

What is claimed is:

1 . A display device comprising:
a display panel; a frame positioned behind the display panel; a plate positioned between the display panel and the frame; and a side frame, which extends along an edge of the frame behind the frame and which is coupled to the frame, wherein the plate comprises: a base facing the frame; and a projection, which projects rearwards from the base through the frame and the side frame and which is bent at an end thereof so as to be coupled to the side frame.

2 . The display device according to claim 1 , wherein the frame has therein a through hole, through which the projection extends, and the side frame has therein a coupling hole, through which the projection extends,
wherein the projection comprises: a body extending through the through hole and the coupling hole in an anteroposterior direction; and a head, which is bent at an end thereof so as to be in contact with the side frame, and wherein the frame is secured between the base and the head.

3 . The display device according to claim 2 , wherein the side frame comprises:
a coupling portion, which is positioned adjacent to a periphery of the frame and which extends along the edge of the frame while facing a rear surface of the frame; and a cover portion, which intersects the coupling portion and which extends along the edge of the frame so as to cover a lateral surface of the frame, and wherein the coupling hole is formed in the coupling portion, and the head is in contact with a rear surface of the coupling portion.

4 . The display device according to claim 3 , wherein the frame has a thickness smaller than a thickness of the coupling portion.

5 . The display device according to claim 3 , wherein the coupling portion comprises:
a flat portion facing the rear surface of the frame; and a depressed portion, which is depressed forwards from the flat portion so as to be in contact with the rear surface of the frame and in which the coupling hole is formed, and wherein the head is in contact with a rear surface of the depressed portion.

6 . The display device according to claim 5 , wherein the depressed portion comprises:
a first area in which the coupling hole is formed; a second area adjacent to the flat portion; and a third area, which is positioned between the first area and the second area and with which the head is in contact.

7 . The display device according to claim 3 , further comprising:
an extension, which projects from an inner surface of the cover portion and which extends along the inner surface of the cover portion while facing a rear surface of the display panel; and an adhesive member, which is disposed between the display panel and the extension and is coupled thereto.

8 . The display device according to claim 2 , further comprising a protrusion, which projects rearwards from the base and is fitted into the frame,
wherein the frame has a coupling hole into which the protrusion is fitted, wherein the projection is positioned adjacent to a periphery of the base, and wherein the protrusion is spaced apart from the projection in an inward direction of the base.

9 . The display device according to claim 8 , wherein the projection is configured to have a form of a hollow cylinder, and the protrusion is configured to have a form of a solid cylinder.

10 . The display device according to claim 2 , wherein the frame comprises:
a contact portion contacting a rear surface of the plate; and a reinforcing portion, which is depressed rearwards from the contact portion so as to be spaced apart from the rear surface of the plate, and wherein the through hole is formed in the contact portion.

11 . The display device according to claim 10 , further comprising a back cover configured to cover a rear surface of the frame, the back cover being coupled to the reinforcing portion.

12 . The display device according to claim 11 , wherein the back cover comprises:
a side cover, which is positioned adjacent to the side frame and which has a hole through which air is introduced and discharged; and a middle cover coupled to the side cover.

13 . The display device according to claim 12 , wherein the middle cover is coupled to the reinforcing portion and is spaced apart from the contact portion so as to provide a flow channel for the air passing through the hole.

14 . The display device according to claim 12 , wherein the middle cover comprises a metal material, and the side cover comprises a plastic material.
