Also, a sub mold part for receiving the sub LCD panel comprises a black-colored material so as to prevent reflection of the light. Accordingly, thickness and power consumption of the backlight assembly may be reduced and display quality may be also improved by preventing leakage of the light at ends of the sub LCD panel.
a light guide part including a first exit surface and a second exit surface opposite to the first exit surface, the light guide part receiving the light from the light source and emitting the received light through the first and second exit surfaces;
a receiving container receiving the light source and light guide part, wherein the receiving container includes an opening; and
a leakage preventing member disposed around the opening to prevent a leakage of the light.
2. The backlight assembly of claim 1, wherein the receiving container comprises a protruding portion formed at one end of the opening.
3. The backlight assembly of claim 2, wherein the leakage preventing member contacts a side of the protruding portion.
4. The backlight assembly of claim 2, wherein the leakage preventing member comprises a black-colored tape.
5. The backlight assembly of claim 2, further comprising a reflection/transmission sheet disposed on the second exit surface of the light guide part.
6. The backlight assembly of claim 2, wherein the leakage preventing member comprises a mold part including an engaging recess corresponding to the protruding portion, the mold part comprising a flat material to prevent a reflection of light.
7. The backlight assembly of claim 2, wherein the leakage preventing member comprises a mold part including an engaging recess corresponding to the protruding portion, the mold part comprising a black-colored material to prevent a reflection of light.
8. The backlight assembly of claim 1, wherein the leakage preventing member comprises a black-colored material.
9. The backlight assembly of claim 1, wherein the leakage preventing member comprises a flat material.
10. The backlight assembly of claim 1, wherein the light guide part comprises a first light guide plate including the first exit surface and a second light guide plate including the second exit surface.
11. The backlight assembly of claim 10, wherein the light guide part further comprises a reflection plate disposed between the first and second light guide plates.
a light guide part including a first exit surface and a second exit surface opposite to the first exit surface;
a first liquid crystal display panel assembly disposed over the first exit surface of the light guide part;
a receiving container receiving the light source, the light guide part, and the first liquid crystal display panel assembly, wherein the receiving container includes an opening;
a second liquid crystal display panel assembly disposed below the opening; and
13. The liquid crystal display apparatus of claim 12, wherein the leakage preventing member comprises a portion overlapping with the light guide part and the first and second liquid crystal display panel assembly in a vertical direction.
14. The liquid crystal display apparatus of claim 12, wherein the receiving container comprises a protruding portion formed at one end of the opening.
15. The liquid crystal display apparatus of claim 14, wherein the leakage preventing member contacts a side of the protruding portion.
16. The liquid crystal display apparatus of claim 14, further comprising a reflection/transmission sheet disposed on the second exit surface of the light guide part.
17. The liquid crystal display apparatus of claim 12, further comprising a mold part coupled to the receiving container, wherein the mold part includes a plurality of sidewalls corresponding to the opening.
18. The liquid crystal display apparatus of claim 17, wherein the leakage preventing member is partially disposed between the light guide part and the plurality of sidewalls.
19. The liquid crystal display apparatus of claim 12, wherein the leakage preventing member comprises a black-colored material.
20. The liquid crystal display apparatus of claim 12, wherein the leakage preventing member comprises a flat material.
