Title:
METHOD OF MANUFACTURING ROLL-SHAPED DIE FOR OPTICAL SHEET MANUFACTURE, OPTICAL SHEET MANUFACTURING METHOD, ELECTRONIC DISPLAY DEVICE, AND MIRROR SURFACE PROCESSING METHOD OF ALUMINUM BASE MATERIAL
Document Type and Number:
WIPO Patent Application WO/2013/054832
Kind Code:
A1
Abstract:
Provided is a roll-shaped die for optical sheet manufacture capable of suppressing pattern interference even when streak-form irregularities resulting from cutting marks have been transferred to the antireflective film. In this roll-shaped die (1) for optical sheet manufacture, fine irregularities are formed on the outer circumference surface, and, while contacting an elongate sheet to said outer circumference surface, the fine irregularities are transferred to the elongate sheet, forming an elongate optical sheet material. On the outer circumference surface (1a) of this roll-shaped die for optical sheet manufacture, in addition to the fine irregularities, multiple streak-form irregularities (1b) are formed extending in rows with an arrangement period (P) of 5-50μm.
