摘要

The present invention includes a releasable temporary support, a / 4 plate and a reflective polarizer in this order, the reflective polarizer includes a light reflecting layer in which a cholesteric liquid crystal phase is fixed, and the / 4 plate and the light reflection All of the layers are a coating material of a polymerizable liquid crystal composition containing a liquid crystal compound, a transfer material of a brightness enhancement film having a film thickness of 8 m or more and 30 m or less, an orientation provided on the surface of a temporary support or a temporary support A method of producing the transfer material including applying a polymerizable liquid crystal composition containing a liquid crystal compound on the surface of the layer and curing the obtained coating film to form a / 4 plate, a method of manufacturing the transfer material from the transfer material, , A method for producing an optical sheet member including adhering a peeled surface from which the temporary support is peeled off from the transfer material to a polarizing plate, and an optical sheet member obtained by the above manufacturing method are provided To . A thin film optical sheet member can be provided by using the transfer material of the present invention.
