Abstract
The present invention provides a gas barrier film comprising a composite film provided with a gas barrier layer having a laminated structure including at least a metal oxide thin layer on a substrate film having a (1) 80 ppm/°C. or less coefficient of thermal expansion at 50° C. to 150° C. and/or a 10 ppm/% RH or less coefficient of humidity expansion at 25° C., and a (2) 150C.° or more glass transition temperature, and a display with a display element covered with the same.
Claims15
A gas barrier film comprising a composite film provided with a gas barrier layer having a laminated structure including at least a metal oxide thin layer on a substrate film having a (1) 80 ppm/°C. or less coefficient of thermal expansion at 50° C. to 150° C. and/or a 10 ppm/% RH or less coefficient of humidity expansion at 25° C., and a (2) 150C.° or more glass transition temperature.
Use of a substrate film in the gas barrier film application, wherein the substrate film has a (1) 80 ppm/°C. or less coefficient of thermal expansion at 50° C. to 150° C. and/or a 10 ppm/% RH or less coefficient of humidity expansion at 25° C., and a (2) 150C.° or more glass transition temperature.
A display with at least one surface of a display element covered with a gas barrier film, wherein the gas barrier film comprises a composite film provided with a gas barrier layer having a laminated structure including at least a metal oxide thin layer on a substrate film having a (1) 80 ppm/°C. or less coefficient of thermal expansion at 50° C. to 150° C. and/or a 10 ppm/% RH or less coefficient of humidity expansion at 25° C., and a (2) 150C.° or more glass transition temperature.
