Patent ID: 7901767

Claim:
A gas barrier laminate comprising an organic layer and an inorganic layer laminated thereon, wherein the water vapor permeability per one inorganic layer that constitutes the gas barrier laminate, at 40° C. and a relative humidity of 90%, is at most 1×10−3 g/m 2 ·day, wherein the organic layer comprises, as the main ingredient thereof, a polymer having a structural unit of the following formula (2) wherein n is 2 and a structural unit of the following formula (2) wherein n is 3 or more: (Z—COO) n -L Formula (2) wherein Z is represented by the following (a) or (b): R 2 and R 3 in the structures each independently represent a hydrogen atom or a methyl group: * indicates the position at which the structure bonds to the carbonyl group in formula (2): L represents an n-valent linking group: a number n of Z's may be the same or different, but at least one Z is represented by the following (a): and, wherein the thickness of the inorganic layer is from 20 to 60 nm.
