Title:
ガスバリアー性フィルムの製造方法及び電子デバイスの製造方法
Document Type and Number:
Japanese Patent JP6652048
Kind Code:
B2
Abstract:
The purpose of the present invention is to provide a method of manufacturing a gas barrier film which uses a film substrate material containing a cyclic olefin polymer or a cyclic olefin copolymer and which suppresses the occurrence of breaking and cracking in the film substrate material. This gas barrier film manufacturing method involves providing a clear hard coating layer (3) and a gas barrier layer (5), in that order, on a film substrate (2) that contains a cyclic olefin polymer or a cyclic olefin copolymer, and is characterized by involving a step in which, before providing the clear hard coating layer (3), a protective laminate member (9) is provided on the surface of the film substrate (2) opposite of the surface on which the clear hard coating layer (3) will be provided, and a step in which the ends in the width direction of the laminate body that includes the film substrate (2) and the protective laminate member (9) are cut such that the dimension of the film substrate (2) in the width direction is the same as the dimension of the protective laminate member (9) in the width direction.
