PURPOSE:To enable a color display without being limited by the balance between the number of colors and transmissivity by forming a polymer by photopolymn. of a polymerizable liquid crystal compsn. in such a manner that the optical phase difference partly differs in the layer. CONSTITUTION:This film has a polymer layer comprising a polymerizable liquid crystal compsn. in which the optical phase difference partly differs. As for the polymerizable liquid crystal compsn., a compsn. containing unifunctional acrylate or unifunctional methacrylate and showing a liquid crystal phase is preferably used. The unifunctional acrylate or unifunctional methacrylate is an acrylate or methacrylate of cyclic alcohol, phenol or aromatic hydroxy compd. having a liquid crystal structure having at least two six-member rings as a partial structure. Undesirable thermal polymn. is thereby prevented in the photopolmn. process in a liquid crystal state and a uniform orientation state can be fixed. The polymer layer is preferably formed to 0.1-100mum thick. |
