Title:
LAMINATE
Document Type and Number:
Japanese Patent JP2020147029
Kind Code:
A
Abstract:
To provide a laminate having a plurality of portions where a substrate film and an optical functional layer are laminated, in which the substrate film in a desired portion can be preferentially peeled from the optical functional layer.SOLUTION: A laminate 10 includes a first substrate film 1A, a first optical functional layer 2A including a layer of a cured product of a first polymerizable liquid crystal compound, a second optical functional layer 2B including a layer of a cured product of a second polymerizable liquid crystal compound, and a second substrate film 1B, in this order. An in-plane peeling force P1 between the first substrate film 1A and the first optical functional layer 2A, and an in-plane peeling force P2 between the second substrate film 1B and the second optical functional layer 2B satisfy expression (1) 0.67
