Title:
複合フィルムおよび有機電界発光装置
Document Type and Number:
Japanese Patent JP6768846
Kind Code:
B2
Abstract:
A composite film includes at least one phase difference layer, a substrate, and an inorganic layer, in which the phase difference layer is a layer formed by curing a composition including a liquid crystal compound, the inorganic layer includes silicon nitride, a distance between the substrate and a surface of the composite film is 60 μm or less, with respect to each of the layers other than the substrate, a product E×t×1 of a modulus of elasticity E in unit of GPa, a thickness t in unit of μm, and a distance 1 from a surface of the substrate to a center of each of the layer in unit of μm satisfies Expression 1, and a total SUM(E×t×1) of E×t×1 of each of the layers other than the substrate satisfies Expression 2, 0.8≤E×t×1 (Expression 1), SUM(E×t×1)≤1500 (Expression 2); and the composite film.
