Abstract
A gas barrier film includes a support, a gas barrier layer provided on one surface of the support and including an inorganic layer, and a deformation inhibition layer provided on a surface of the support opposite to a surface on which the gas barrier layer is provided and including a bifunctional or higher (meth)acrylate, in which the support has a thermal expansion coefficient of 30×10−6/° C. or greater, and the (meth)acrylate of the deformation inhibition layer has a volume shrinkage rate of 3% to 20%.
