Abstract

Disclosed is a display apparatus which is light and slim in its external appearance. The display apparatus includes a display panel which displays an image signal; a backlight unit which provides light to the display panel; a front member which includes a body whose central portion is open such that an image displayed on the display panel can be frontwardly exposed, and a support unit which supports the display panel and the backlight unit in the inner side of the body; and a rear member which is coupled to the front member and supports the back side of the backlight unit.

Claims

1. A display apparatus comprising:

a display panel which displays an image signal;

a backlight unit which provides light to the display panel;

a front member which includes a body whose central portion is open such that an image displayed on the display panel is frontwardly exposed, and a support unit which supports the display panel and the backlight unit in an inner side of the body; and

a rear member which is coupled to the front member and supports a back side of the backlight unit.

2. The display apparatus according to claim 1, wherein the backlight unit further includes a light source which emits light to be provided to the display panel, and

wherein heat generated in the light source is radiated through the front member.

3. The display apparatus according to claim 1, wherein the support unit of the front member includes an opening which exposes the image displayed on the display panel frontward, a panel support which accommodates and supports the display panel, and a backlight support which accommodates and supports the backlight unit.

4. The display apparatus according to claim 3, wherein the backlight unit includes a light source which emits light to be provided to the display panel, and a light guide plate which supplies the light emitted from the light source uniformly, and

wherein the light source is arranged as an edge type light source disposed along at least one lateral side of the light guide plate, and heat generated from the light source is radiated through the backlight support of the front member.

5. The display apparatus according to claim 4, wherein the light source includes at least one LED and an LED board which supports the at least one LED, and

wherein the LED board is coupled to the backlight support of the front member.

6. The display apparatus according to claim 1, wherein the front member includes a material having high thermal conductivity.
