Abstract
Disclosed are a backlight for providing an enhanced brightness of light with a lower consumption of electricity and a liquid crystal display device using thereof. A light guide plate has brightness enhancing recesses formed on a bottom surface thereof and light collecting grooves formed on an upper surface thereof. The brightness enhancing recesses efficiently reflect the light having different directions and the light collecting grooves collects the light reflected by the brightness enhancing recesses. A loss of the light generated by a lamp may be minimized, resulting in enhancing the brightness of the light. Thus, the consumption of the electricity can be greatly reduced.
Claims7
A backlight assembly comprising:
- a lamp assembly for generating and emitting light in a first direction;
- and
- a first light guide plate for enhancing a brightness of the light, the light guide plate including a body for guiding the light transmitted from the lamp assembly, which has at least one brightness enhancing groove that is formed on a bottom surface thereof and has a polyhedron horn shape.
A liquid crystal display device comprising;
- a liquid crystal display panel assembly for controlling liquid crystal precisely to display an image;
- and
- a backlight assembly including a lamp assembly for generating and emitting light in a first direction, a light guide plate for guiding the light provided from the lamp assembly, which has a plurality of the recesses for enhancing a brightness of the light formed in a polyhedron horn shape on a bottom surface thereof, optical sheets for transmitting the light out of the light guide plate and a receptacle for receiving the lamp assembly, the light guide plate and the optical sheets, said receptacle being combined with the liquid crystal display panel assembly.
