Abstract

A display apparatus includes a display panel which displays an image, a backlight unit which provides light to the display panel, a heat sink plate adjacent to the backlight unit, the heat sink plate including a catch portion on one side surface thereof, and a mold frame between the display panel and the backlight unit, the mold frame including a first hook which is coupled with the catch portion.

Claims (28)

1. A display apparatus comprising:

a display panel which displays an image;

a backlight unit including a light source configured to generate light, and a light guide plate on a side of the light source, the light guide plate configured to guide the light to the display panel;

a heat sink plate adjacent to the backlight unit, and including:

a bottom portion,

a sidewall portion extended from the bottom portion, and

a catch portion extended from the sidewall portion and away from the backlight unit, the catch portion including a single lower surface elongated in a first direction;

a mold frame between the display panel and the backlight unit, and including a plurality of first hooks which contacts with the single lower surface of the catch portion of the heat sink plate; and

a bottom chassis which receives the display panel, the backlight unit, and the heat sink plate, and exposes a portion of the bottom portion of the heat sink plate proximate to the light source,

wherein the exposed portion of the bottom portion of the heat sink plate is thicker than a portion of the bottom portion of the heat sink plate between the backlight unit and the bottom chassis.

2. The display apparatus of claim 1 , further comprising a top chassis comprising:

a first portion which overlaps an edge of the display panel; and

a second portion which extends from the first portion, and includes a second hook which couples with the catch portion of the heat sink plate.

3. The display apparatus of claim 2 , wherein the second portion of the top chassis further includes a window, and the window exposes a first hook among the plurality of first hooks of the mold frame to an outside of the display apparatus.

4. The display apparatus of claim 3 , wherein

the second hook and the window of the top chassis are provided in plurality, and

the plurality of second hooks and windows alternate in the first direction in which the single lower surface of the catch portion of the heat sink plate is elongated.

5. A display apparatus comprising:

a display panel which displays images;

a backlight unit which generates light and provides the light to the display panel;

a top chassis including a first sidewall portion in a non-display area of the display apparatus, the sidewall portion including a first coupling member;

a heat sink plate including:

a bottom portion,

a second sidewall portion in the non-display area of the display apparatus, the second sidewall portion extending from the bottom portion, and

a second coupling member extended from the second sidewall portion and away from the backlight unit, the second coupling member including a single lower surface elongated in a first direction; and

a mold frame between the top chassis and the heat sink plate, and including a third sidewall portion in the non-display area of the display apparatus, the third sidewall portion including a third coupling member,

wherein both the first coupling member of the top chassis and the third coupling member of the mold frame contact with the single lower surface of the second coupling member of the heat sink plate, in the non-display area of the display apparatus.

6. The display apparatus of claim 5 , wherein the first coupling member of the top chassis and the third coupling member of the mold frame alternately contact the single lower surface of the second coupling member of the heat sink plate in the first direction.
