Patent ID: 7288297

Claim:
An optical compensation plate, comprising an optical compensation layer, wherein an anti-cracking layer containing a moisture-curing isocyanate compound is laminated directly on at least one surface of the optical compensation layer, wherein the anti-cracking layer has a glass transition temperature (Tg) of 100° C. or less in a cured state and the moisture-curing isocyanate compound is hexamethylenediisocyanate or 1,3-bis(isocyanatomethyl)cyclohexane, said optical compensation layer is a cholesteric layer whose constituent molecules are aligned in the form of a cholesteric structure, a constituent molecule of the cholesteric layer is produced from a liquid crystal monomer and a chiral dopant, the liquid crystal monomer is at least one selected from the group consisting of: a compound represented by the below formula (4); a compound represented by the below formula (5); a compound represented by the below formula (6); a compound represented by the below formual (7); a compound represented by the below formula (8); a compound represented by the below formula (9); a compound represented by the below formula (10); a compound represented by the below formula (11); a compound represented by the below formula (12); a compound represented by the below formula (13) a compound represented by the below formula (14); a compound represented by the below formula (15); a compound represented by the below formula (16); a compound represented by the below formula (17); a compound represented by the below formula (18); and a compound represented by the below formula (19), and the chiral dopant is at least one selected from the group consisting of a compound represented by the below formula (24); a compound represented by the below formula (25); a compound represented by the below formula (26); a compound represented by the below formula (27); a compound represented by the below formula (28); a compound represented by the below formula (29); a compound represented by the below formula (30); a compound represented by the below formula (31); a compound represented by the below formula (32); a compound represented by the below formula (33); a compound represented by the below formula (34); a compound represented by the below formula (35); a compound represented by the below formula (36); a compound represented by the below formula (37); a compound represented by the below formula (38); a compound represented by the below formula (39); a compound represented by the below formula (40); a compound represented by the below formula (41); a compound represented by the below formula (42); a compound represented by the below formula (43); and a compound represented by the below formula (44)
