| titleOfInvention | Retardation film and method for producing the same |
| abstract | A method for producing a retardation film comprising a plurality of layers of different resins and having an in-plane slow axis of each layer uniform in the width direction is provided. A first stretching step of stretching a long unstretched film comprising a layer a of resin A and a layer b of resin B in a first direction to obtain a first stretched film, and a first stretched film comprising: A second stretching step in which a second stretched film is obtained by stretching in a second direction orthogonal to the first direction, and the glass transition temperature TgA of the resin A and the glass transition temperature TgB of the resin B are TgA + 5 (° C. ) ≦ TgB is satisfied, and in the first stretching step, stretching is performed under conditions where bowing that can offset the bowing that occurs in the resin B layer b by the second stretching step occurs in the resin B layer b of the first stretched film, In the second stretching step, stretching is performed under the condition that the molecular orientation angle of the layer A of the resin A of the second stretched film is in the range of −0.5 ° to 0.5 ° with respect to the second direction.
