ABSTRACT:
The present invention relates to an optical efficiency enhancing film and an LCD using the same. The LCD of the present invention is provided with an optical efficiency enhancing film that includes uniaxial films made of a refractive index anisotropic material and isotropic films, wherein the uniaxial films and the isotropic films are alternatively laminated. Then, optical efficiency as well as polarization may be enhanced to thereby improve the brightness of the LCD.
