| abstract | A step of forming a layered body including a resin layer (a) containing a resin A having positive intrinsic birefringence and a resin layer (b) containing a resin B having negative intrinsic birefringence, the resin layer (b) being provided on one side of the resin layer (a); a first stretching step of stretching the layered body in one direction at a temperature T1; and a second stretching step of, after the first stretching step, stretching the layered body in another direction that is approximately orthogonal to the previous stretching direction at a temperature T2 which is lower than the temperature T1 to obtain a phase difference plate are performed. By these steps, a phase difference plate wherein a slow axis of the resin layer (a) after the stretching treatment and a slow axis of the resin layer (b) after the stretching treatment are approximately parallel to each other, and in-plane retardation Rea and NZ coefficient NZa in the resin layer (a) after the stretching treatment, and in-plane retardation Reb and NZ coefficient NZb in the resin layer (b) after the stretching treatment satisfy specific relationship is obtained. |
