Abstract

The liquid crystal display includes: a liquid crystal panel; a backlight unit that includes a light guide plate that is positioned at a lower part of the liquid crystal panel and that guides light emitted from a light source in a direction of the liquid crystal panel, and a plurality of optical sheets that provide light emitted from the light guide plate to the liquid crystal panel; and a plurality of step parts that are formed from a base surface to an upper surface in order to receive the liquid crystal panel and the backlight unit, wherein a step part facing the liquid crystal panel among the plurality of step parts includes a main support having an area patterned to be apart from the liquid crystal panel.

Claims (15)

1. A liquid crystal display (LCD) comprising:

a liquid crystal panel;

a backlight unit that comprises a light guide plate that is positioned at a lower part of the liquid crystal panel and that guides light emitted from a light source in a direction of the liquid crystal panel, and a plurality of optical sheets that provide light emitted from the light guide plate to the liquid crystal panel; and

a plurality of step parts that are formed from a base surface to an upper surface in order to receive the liquid crystal panel and the backlight unit,

wherein a step part facing the liquid crystal panel among the plurality of step parts comprises a main support having an area patterned to be apart from the liquid crystal panel,

wherein the plurality of step parts comprise a first step part to support a reflective sheet and the light guide plate, a second step part to support the optical sheets, a third step part to support the liquid crystal panel and a fourth step part to support an upper support,

wherein the patterned area is a rip area that is positioned at the center of the main support,

wherein the patterned area has a depressed pattern, the patterned area formed at the third step part.

2. The LCD of claim 1 , wherein the patterned area is depressed in a rectangular form.

3. The LCD of claim 2 , wherein a surrounding area of the patterned area has an inclined slope surface.

4. The LCD of claim 3 , wherein an upper corner area of the inclined slope surface has a round shape.

5. The LCD of claim 1 , wherein the patterned area has a slope surface inclined toward the center of the patterned area.

6. The LCD of claim 1 , wherein a width of the patterned area is narrower than that of a surface of a step part facing the liquid crystal panel.

7. The LCD of claim 1 , wherein a black frame for exposing a display area of the liquid crystal panel and blocking a non-display area thereof is positioned between the liquid crystal panel and the plurality of optical sheets.

8. The LCD of claim 7 , wherein a height of the patterned area is equal to or lower than that of the black frame.
