THE METHOD OF FILM TYPE PATTERNED RETARDER FOR 3D DISPLAY

摘要

PURPOSE: A manufacturing method of a pattern retarder of 3D display film type, which secures stability of a liquid crystal coating solution and, uses a composition of the Diacrylate type reactive liquid crystal able to maintain phase deference of a liquid crystal layer of a product, is provided. CONSTITUTION: A manufacturing method of a pattern retarder (FPR, Film-Type Patterned Retarder) of 3D display film type includes: the first step of coating the TAC (Triacetyl Cellulose) group film substrate with the alignment film and then drying it; the second step of exposing a first linear polarization and then exposing a second polarization in order for the TAC group film on which the alignment layer is coated is to be at 90 for each pattern; and the third step of coating a reactive liquid crystal on the exposed alignment layer, drying, and hardening. [Reference numerals] (AA) Dry after an alignment layer is coated on a TAC (Triacetyl Cellulose) group film; (BB) Second exposure of a linear polarization after a first exposure of a linear polarization to form 90 degrees at each pattern; (CC) Harden after a reactive liquid crystal is coated and dried ( a weight ratio of Monoacrylate : Diacrylate = 40-20 : 60-80); (DD) Pattern retarder of a 3D display film type to maintain a phase difference of a liquid crystal layer under high temperature and humid environment
