- the gradually narrowing portion is set to be narrower in a linear function, and is formed into a trapezoidal shape.
- the slit S used for the exposure process is gradually narrowed toward the end in the longitudinal direction, thereby transporting the substrate at a high speed. Even when the exposure process is performed in a state of being wound around a roll, sufficient accuracy can be ensured, whereby a pattern retardation film can be produced easily and in large quantities with high accuracy.
- the slit S may have a triangular shape at both ends in the longitudinal direction. Further, the slit S gradually becomes wider by a change in a curve such as a quadratic function instead of a linear change. It may be narrowed. In addition, as shown in FIG. 7, when a practically sufficient accuracy can be ensured, only one side may be gradually narrowed.
- the present invention is not limited to this, and can be widely applied to various types of exposure processing using a mask.
- the right eye region and the left eye region are used. For example, each region is aligned by exposure processing using a mask.
- the present invention is not limited to this, and on the premise of using an organic EL panel or a plasma display panel.
- the present invention can be widely applied also when the polarizing filter is provided integrally.
