LCD backlight system using light emitting diode chip

An LCD comprising:

• a liquid crystal panel;
• and
• a backlight system to irradiate light toward the liquid crystal panel,
• wherein the backlight system comprises:
• a plurality of light emitting devices arranged on a base plate to form a plurality of lines;
• and
• a light guide panel having a sidewall spaced apart from the plurality of light emitting devices such that light incident from the plurality of light emitting devices is dispersed by inner reflection, and a scattering region formed adjacent to the base plate such that light incident into the scattering region is irregularly reflected to be emitted away from the base plate.

A backlight system, comprising:

• a base plate;
• a plurality of light emitting devices arranged in lines on the base plate;
• a plurality of light guide panels, disposed on the base plate to surround opposite sides of the lines of light emitting devices;
• and
• a plurality of scattering regions disposed between the base plate and a surface of the plurality of light guide panels adjacent to the base plate,
• wherein a light emitted by the light emitting devices parallel to the base plate is incident to the plurality of light guide panels, each light guide panels disperses the incident light by inner reflection, and the plurality of scattering regions irregularly reflect the dispersed light away from the base plate.
