Light diffusion member, back light assembly including the same and display device including the same |
摘要 |
The light diffusion member includes a light diffusing body and a light diffusing layer. The light diffusing body includes a polymer mixture obtained by uniformly blending a first polymer having a first glass transition temperature and a second polymer having a second transition temperature higher than the first transition temperature. Alternatively, the light diffusing body includes a copolymer prepared from the first and the second polymer. The light diffusing body diffuses an incident light through a light exiting surface. The light diffusing layer is formed on the light exiting surface of the light diffusing body and includes a binder resin having beads. A back light assembly including the light diffusion member and a liquid crystal display device including the light diffusion member exhibit an improved luminance and an improved light diffusing efficiency.
