Abstract

Disclosed is an LCD apparatus having a reduced size and weight. The LCD apparatus includes a bottom chassis having a bottom surface and first to fourth sidewalls. The sidewall of the bottom chassis includes a supporting member for preventing a light guiding plate from being moved and a fixing boss for fixing an optical sheet. The bottom chassis includes a lamp insertion portion for receiving a lamp unit, which is disposed on the third and fourth sidewalls of the bottom chassis. The bottom chassis receives a reflecting plate, the light guiding plate and the optical sheet. A mold frame is coupled to the bottom chassis to fix the reflecting plate, the light guiding plate and the optical sheet to the bottom chassis. A display unit disposed on the mold frame is fixed to the mold frame by a top chassis coupled to the mold frame. Accordingly, a bottom mold frame for receiving a backlight assembly is removed, so that it is able to reduce a cost of the LCD apparatus and a weight thereof.

Claims

1-20. -20. (canceled)

21. A backlight assembly comprising:

a first light source generating light, the first light source extending a first direction;

a light guiding unit guiding the light generated by the first light source; and

a receiving unit having a bottom surface and four sidewalls to form a receiving space receiving the first light source adjacent to a first sidewall of the four sidewalls and the light guide unit adjacent to the light source, the receiving space including a first insertion portion adjacent to the first sidewall through which the first light source is slid in the first direction to be guided into a receiving position.

22. The backlight assembly of claim 21, wherein the light source comprises a lamp generating the light and a lamp covering the lamp and reflecting the light toward the light guiding unit.

23. The backlight assembly of claim 21, further comprising a second light source adjacent to a second sidewall of the four sidewalls opposite to the first sidewall, the second light source extending the first direction,

wherein the receiving space further includes a second insertion portion adjacent to the second sidewall through which the second light source is slid in the first direction to be guided into a receiving position.

24. The backlight assembly of claim 21, wherein the first sidewall comprises a body portion connected to the bottom surface and a guiding portion bending from the body portion to cover an end portion of an upper surface of the light source.

25. The backlight assembly of claim 24, wherein a second sidewall of the four sidewalls adjacent to the first sidewall is separated from the first sidewall and an opening between the first sidewall and the second sidewall serves as the insertion portion.

26. The backlight assembly of claim 24, wherein the body portion comprises a first portion corresponding to the first receiving space and a second portion corresponding to an outside of the first receiving space, and the guiding portion is bent from an upper end of the second portion of the body portion.

27. An LCD apparatus comprising:

a display panel displaying an image using light; and

a backlight assembly including;

a light source generating the light, the light source extending a first direction;

a light guiding unit guiding the light generated by the light source into the display panel; and

a receiving unit having a bottom surface and four sidewalls to form a receiving space including a first receiving space adjacent to a first sidewall of the four sidewalls extending in the first direction in which the light source is received and a second receiving space adjacent to the first receiving space in which the light guiding unit is received, the first receiving space having an insertion portion through which the light source is slid to be guided into a receiving position.

28. The backlight assembly of claim 27, wherein the first sidewall comprises a body portion connected to the bottom surface and a guiding portion bending from the body portion to cover an end portion of an upper surface of the light source.

29. The backlight assembly of claim 28, wherein a second sidewall of the four sidewalls adjacent to the first sidewall is separated from the first sidewall and an opening between the first sidewall and the second sidewall serves as the insertion portion.

30. The backlight assembly of claim 28, wherein the body portion comprises a first portion corresponding to the first receiving space and a second portion corresponding to an outside of the first receiving space, and the guiding portion is bent from an upper end of the second portion of the body portion.
