OPTICAL FILM, LIQUID CRYSTAL PANELS AND LIQUID CRYSTAL DISPLAYS

摘要

The invention provides an optical film which can realize a liquid crystal display enabling colorless neutral display in all azimuths and high contrast and which little suffers from knick defects; liquid crystal panels made by using the film; and liquid crystal displays made by using the panels. An optical film which comprises a transparent protective film, a polarizer, and a birefringent layer that is made of a cycloolefinic film and satisfies the relationship: 1 2 [wherein Nz=(nx-nz)/(nx-ny)] in this order and in which the polarizer and the birefringent layer are directly laminated with a polyvinyl alcohol-base adhesive containing a metal compound colloid between both.
