<P>PROBLEM TO BE SOLVED: To provide an elliptically polarizing plate which has an excellent characteristic with respect to the oblique direction and has a broad band region and a wide viewing angle. <P>SOLUTION: The manufacturing method of elliptically polarizing plate comprises a process of forming a first birefringence layer on a surface of a transparent protective film, a process of laminating a polarizer on another surface of the transparent protective film and a process of forming a second birefringence layer on the surface of the first birefringence layer, wherein the first birefringence layer and the polarizer are arranged on the opposite sides to each other of the transparent protective film. The process of forming the first birefringence layer comprises a process of applying a liquid crystal material to an alignment substrate, a process of forming the first birefringence layer on the substrate by treating the liquid crystal material and a process of transferring the first birefringence layer to the surface of the transparent protective film, wherein the angle α between an absorption axis of the polarizer and a lagging axis of the first birefringence layer has a prescribed relation to the angle β between the absorption axis of the polarizer and a lagging axis of the second birefringence layer. <P>COPYRIGHT: (C)2007,JPO&INPIT |
