<P>PROBLEM TO BE SOLVED: To provide an optical member which is manufactured through easy operations and is less likely to cause a spectrum shift, at a high temperature. <P>SOLUTION: The optical member has an optical function layer, containing a cured body of a polymerizable liquid crystal composition, a transparent layer, and an adhesion layer interposed in between the optical function layer and transparent layer, and the adhesion layer has a film thickness of 5 to 30 μm and consists of an adhesive composition, comprising a base agent containing a polymer developing adhesiveness and an aromatic ketone compound, having an aromatic group at both sides of two bond lines of a carbonyl group (-CO-), the content rate of the aromatic ketone compound to 100 parts by weight of the polymer being 5 to 20 parts by weight. Also a luminance-improving film constituted of the optical member, a method of manufacturing the same, and a liquid crystal display device including the same are disclosed. <P>COPYRIGHT: (C)2010,JPO&INPIT |
