description | PROBLEM TO BE SOLVED: To provide a method for manufacturing a process sheet original plate for manufacturing an optical diffuser easily.SOLUTION: An uneven pattern-forming sheet 10 includes a base material 11 and a hard layer 12 provided on the one side of the base material 11, and the hard layer 12 has an uneven pattern 12a. The uneven pattern 12a of the uneven pattern-forming sheet 10 includes a wavy uneven shape in substantially one direction, and the wavy uneven pattern 12a is formed in a meandered form. The tip of a projection of the uneven patter 12a is rounded. The thickness of the base material 11 is preferable to be 0.3 to 500 μm. If the thickness of the base material 11 is 0.3 μm or more, the uneven pattern-forming sheet 10 becomes hard to be broken, and if it is 500 μm or less, the uneven pattern-forming sheet 10 can be easily thinned. Moreover, in order to support the base material 11, a 5 to 500 μm thick resin-made support body may be provided. |
