  • Patent number: 9804428
    Abstract: The present invention relates to a composite sheet, to a substrate for a display element including same, and to a display device including same. More specifically, the composite sheet comprises: a reinforcement-impregnated matrix; a coating layer formed on at least one surface of the matrix; and a barrier layer formed on at least one surface of the coating layer, wherein, if an elastic modulus of the matrix is E2 at a temperature of 25° C. and an elastic modulus of the coating layer is E3 at a temperature of 25° C., the ratio of the elastic modulus, i.e. E3/E2, is approximately 5×104 or less.
