RETARDATION FILM AND LIQUID CRYSTAL DISPLAY DEVICE HAVING THE SAME

摘要

PURPOSE: A phase difference film of high optical anisotropy and a liquid crystal display device including the same are provided to efficiently use a phase difference film of a liquid crystal display device for a VA mode. CONSTITUTION: A cellulose component 100 parts by weight includes retardation additive 0.01~30 parts by weight in a formula 1. In case the cellulose component is cellulose acetate, retardation additive component is 0.1~10 parts by weight about the cellulose component 100 parts by weight. A pair of polarizing plates(10) is located in both sides of liquid crystal cell. An upper phase difference film is attached to the polarizing plate in an image display direction. The bottom phase interference film is attached to the polarizing plate in a backlight direction.
