LIGHT DIFFUSION PLATE HAVING BOTTOM SURFACE FOR RECEIVING INCIDENT LIGHT FROM LIGHT SOURCE, BACKLIGHT UNIT INCLUDING THE SAME, LIQUID CRYSTAL DISPLAY DEVICE, AND LIGHTING DEVICE

摘要

PURPOSE: A light diffusion plate, a backlight unit including the same, a liquid crystal display, and a lighting device are provided to obtain luminance and uniformity by vertically arranging a protrusion of a first base material layer and a protrusion of a second material layer to each other. ;CONSTITUTION: A light incidence surface(112) is formed to receive incident light from a light source through a bottom surface. A cross section of an upper side has an elliptic shape. Protrusions formed in a lateral direction are continuously formed in a longitudinal direction. Each of first and second base material layers includes a light emission surface(113) through which the light is emitted to the outside of the protrusion. A protrusion of a first base material layer(110) and a protrusion of a second base material layer are arranged perpendicularly to each other.;COPYRIGHT KIPO 2011
