BACK LIGHT ASSEMBLY AND LIQUID CRYSTAL DISPLAY HAVING THE SAME

摘要

A back light assembly and an LCD(Liquid Crystal Display) are provided to reduce the thickness of the back light assembly by mounting a reflecting plate and optical sheets in a space formed by the first reflecting plane and the third projection plane of a light guide plate. A back light assembly(1000) includes a light source(200) for generating light, a light guide plate(300), a mold frame(400), and a reflecting plate(500). The light guide plate includes a light receiving plane, a projection plate extended from one end of the light receiving plane, and a reflecting plane extended from the other end of the light receiving plane. The reflecting plane has the first reflecting plane tilted from the other end of the light receiving plane at a predetermined angle and the second reflecting plane extended from the first reflecting plane in a direction perpendicular to the light receiving plane. The mold frame accommodates the light source and the light guide plate. The reflecting plate is located between the reflecting plane and the mold frame to reflect light leaked to the reflecting plane.
