Title:
OPTICAL FILM, AND LIQUID CRYSTAL DISPLAY INCLUDING SAME
Document Type and Number:
WIPO Patent Application WO/2012/091304
Kind Code:
A3
Abstract:
The present invention relates to an optical film and to a liquid crystal display including same. The optical film includes: a first compensation layer in which the refractive index (n1X, n1y) in the X and Y directions on a plane and the refractive index (n1z) in the thickness direction satisfy the following conditions: n1z>n1x>n1y; a second compensation layer in which the refractive index (n2x, n2y) in the X and Y directions on the plane and the refractive index (n2z) in the thickness direction satisfy the following conditions: n2x>n2y>n2z. According to the optical film and the liquid crystal display including same, the lateral viewing angle of the display may be significantly improved, and an optical film for a horizontal alignment mode may be exclusively used to enable mass production and reduce manufacturing costs.
