Light diffusion member, back light assembly including the same and display device including the same

A light diffusion member comprising:

• a light diffusing body including a polymer mixture of polyethylene terephthalate/polycarbonate having polyethylene terephthalate and polycarbonate uniformly blended within the polymer mixture, the light diffusing body diffusing incident light through a light exiting surface of the light diffusing body;
• and
• a light diffusing layer formed on the light exiting surface of the light diffusing body and including a binder resin including beads.

A light diffusion member comprising:

• a light diffusing body including a polymer mixture having a plurality of polymers uniformly blended within the polymer mixture and diffusing an incident light to a light exiting surface of the light diffusing body;
• and
• a light diffusing layer formed on the light exiting surface of the light diffusing body and including a binder resin having beads.

A light diffusion member comprising

• a light diffusing body including a copolymer having a first polymer having a first glass transition temperature and a second polymer having a second glass transition temperature higher than the first glass transition temperature, the first and second polymers arranged as repeating units, the light diffusing body diffusing an incident light through a light exiting surface of the light diffusing body;
• and
• a light diffusing layer formed on the light exiting surface of the light diffusing body and including a binder resin having beads.

A light diffusion member comprising:

• a light diffusing body including a copolymer including polyethylene terephthalate and polycarbonate as repeating units and having a molecular weight of from about 10,000 to about 100,000, the light diffusing body diffusing an incident light through a light exiting surface of the light diffusing body;
• and
• a light diffusing layer formed on the light exiting surface of the light diffusing body and including a binder resin having beads.
