Document Type and Number:
WIPO Patent Application WO/2017/090576
Kind Code:
A1
Abstract:
The present invention addresses the problem of providing a gas barrier film with which gas barrier properties and optical anisotropy are improved. This gas barrier film is characterized by having a gas barrier layer provided on a substrate. The gas barrier film is further characterized in that: the gas barrier layer has, in at least the thickness direction, a mixed region which continues in the thickness direction for at least 5 nm, includes a non-transition metal M1 and a transition metal M2, and in which the value (M2/M1) of the atomic ratio of the transition metal M2 to the non-transition metal M1 is in the range of 0.02-49; and the absolute value of the retardation value Ro of the substrate at a measurement light wavelength of 590 nm, in an environment of 23˚C and 55% RH, is in the range of 0-30 nm.
