PROBLEM TO BE SOLVED: To easily reduce the weight and thickness, to be resistant to impact, to be excellent in flatness and adhesion to an ITO electrode, to be easy to manufacture, to be excellent in gas barrier properties, and to have high performance in a wide band. Of a display device substrate. SOLUTION: The display device comprises a plastic film having an average light transmittance of 70% or more at a wavelength of 400 to 700 nm and a glass transition point of 100 ° C or more, and a gas barrier layer containing an inorganic layered compound and a polymer. Substrate. An embodiment in which the value of the retardation (Re) at a wavelength of 632.8 nm is 15 nm or less, an embodiment in which the inorganic layered compound is synthetic mica, and the like are preferable. |
