Liquid crystal display apparatus
First Claim
1. A backlight assembly comprising:
- a lamp unit for generating a light;
a light guiding unit having a projecting portion for projecting the light, a reflecting portion for reflecting the light to the projecting portion and a side portion which connects the projecting portion with the reflecting portion and receives the light, for guiding the light; and
a receiving unit having a sidewall and a bottom prolonged from the sidewall, for receiving the lamp unit and the light guiding unit, wherein the lamp unit is disposed between the side portion of the light guiding unit and the sidewall of the receiving unit so as to surround the side portion of the light guiding unit.

Abstract
Disclosed is an LCD apparatus for reducing a whole size thereof. The LCD apparatus includes a lamp unit (700), a light guiding unit (800) having a projecting surface, a reflecting surface, and a side surface, and a receiving unit having a sidewall and a bottom prolonged from the sidewall. The lamp unit (700) is disposed between the side surface of the light guiding unit (800) and the sidewall of the receiving unit so that the side surface is surrounded by means of the lamp unit (700). The size of the LCD device can be reduced, and a thickness increase of the LCD apparatus may be prevented while obtaining an enough amount of the light to display an image. Further, the light is uniformly distributed over the whole surface of the light guiding unit (800), and it can prevent the parts of the circuits of the display unit (200) from being damaged.

25. A liquid crystal display apparatus comprising:
-
a lamp unit for generating a light;
a light guiding plate having a projecting portion for projecting the light, a reflecting portion for reflecting the light to the projecting portion and a side portion which connects the projecting portion with the reflecting portion and receives the light, for guiding the light;
a mold frame having a sidewall of which a central portion is opened by a predetermined size and a bottom prolonged from the sidewall, for receiving the lamp unit and the light guiding unit, a reflecting sheet disposed under the light guiding plate and having at least one first guide hole formed at one end, for reflecting the light leaked from the light guiding plate;
a bottom chassis having at least one second guide hole and combined with the mold frame so as to prevent the lamp unit, the light guiding plate and the reflecting sheet from being deviated from the mold frame;
an optical sheet disposed on the light guiding plate, for adjusting brightness of the light emitted from the light guiding plate;
a display unit disposed on the optical sheet, for receiving the light from the optical sheet and displaying an image; and
a top chassis combined with the bottom chassis so as to fix the display unit to the mold frame, wherein the lamp unit is disposed between the light guiding plate and the sidewall of the mold frame to surround the side portion of the light guiding plate. - View Dependent Claims (26, 27, 29, 30, 31, 32, 33, 34, 35, 36, 37, 41, 42, 43)
