The present invention relates to an apparatus for fabricating a light guide panel which can improve light efficiency and brightness, and a backlight unit having the light guide panel. The backlight unit includes a light source for generating a light, and a light guide panel for guiding the light incident thereon from the light source, the light guide panel having an upper pattern which is formed on a front side thereof for emitting the light guided thus to upward and a lower pattern which is formed on a backside thereof for reflecting or refracting the light, wherein the lower pattern of the light guide panel is formed in an intaglio pattern having a vertical angle at which two inclined planes meet, and one of the two inclined planes the light from the light source incident thereon has an angle of 45&#x2dc;55&#xb0;.

A system for testing a distortion of a liquid crystal display (LCD) device can test the LCD device within a chamber in a state of being assembled perpendicular to the ground, whereby whether any distortion occurs in an internal component can be fast detected even in severe conditions of high temperature and high humidity and under an actual installation environment of a user.

System for testing distortion of liquid crystal display device

A liquid crystal display device includes a liquid crystal display panel a driving integrated circuit connected to the liquid crystal display panel and a protection pad disposed on the driving integrated circuit, wherein the protection pad is formed from a material that substantially limits the maximum temperature of the protection pad.
