摘要:
A multifunctional optical sheet for a liquid crystal display device includes a substrate diffusing incident light; a light-concentrating layer on the substrate and including a plurality of patterns that arranged to form alternating peaks and valleys; and reflection patterns between the substrate and the light-concentrating layer corresponding to the valleys of the light concentrating layer.
摘要:
A back light unit is disclosed, which improves condensing efficiency of light and viewing angle characteristics. The back light unit includes at least one lamp generating light, a light guide plate emitting light across a surface thereof using the light generated from the lamp, a diffusion sheet arranged above the light guide plate to diffuse the light passing through the light guide plate, a first condensing sheet condensing the light from the diffusion sheet using a plurality of first elliptical condensing patterns arranged on the diffusion sheet in a first direction, and a second condensing sheet further condensing the light from the first condensing sheet using a plurality of second elliptical condensing patterns arranged on the first condensing sheet in a second direction crossing the first direction.
