Backlight assembly and liquid crystal display device including the same
View Patent ↗A backlight assembly is provided. The backlight assembly includes a mold frame having a tetragonal frame shape and including four side parts and a bottom part extending from bottoms of the side parts, a printed circuit board disposed on the bottom part of the mold frame, at least one light source disposed on the printed circuit board, and a light guide sheet disposed at a side of the light source and accommodated in the mold frame.
1. A backlight assembly comprising:
a mold frame having a tetragonal frame shape and including four side parts and a bottom part extending from bottoms of the side parts;
a printed circuit board printed directly on the bottom part of the mold frame;
at least one light source disposed on the printed circuit board; and
a light guide sheet disposed at a side of the light source and accommodated in the mold frame.
2. The backlight assembly of claim 1 , wherein the light source comprises a light emitting diode.
3. The backlight assembly of claim 1 , further comprising a reflective sheet disposed under the light guide sheet.
4. The backlight assembly of claim 1 , further comprising optical sheets disposed on the light guide sheet.
5. The backlight assembly of claim 1 , further comprising a bottom chassis disposed under the mold frame.
6. A liquid crystal display device comprising:
a liquid crystal panel displaying an image; and
a backlight assembly providing light to the liquid crystal panel,
wherein the backlight assembly includes:
a mold frame having a tetragonal frame shape and including four side parts and a bottom part extending from bottoms of the side parts;
a printed circuit board disposed printed directly on the bottom part of the mold frame;
at least one light source disposed on the printed circuit board; and
a light guide sheet disposed at a side of the light source and accommodated in the mold frame.
7. The liquid crystal display device of claim 6 , wherein the light source comprises a light emitting diode.
8. The liquid crystal display device of claim 6 , further comprising a reflective sheet disposed under the light guide sheet.
9. The liquid crystal display device of claim 6 , further comprising optical sheets disposed on the light guide sheet.
10. The liquid crystal display device of claim 6 , further comprising a bottom chassis disposed under the mold frame.
11. The liquid crystal display device of claim 10 , wherein an edge of the liquid crystal panel is surrounded by a side part of the bottom chassis, and the side part of the bottom chassis is bent and extends inward.
12. The liquid crystal display device of claim 10 , further comprising a top chassis disposed on the liquid crystal panel and coupled to the bottom chassis.
