Abstract: Display device includes a flexible substrate, a plurality of pixels disposed on a first surface of flexible substrate, and a plurality of alignment marks disposed along one side of the flexible substrate and identified each other. The plurality of alignment marks may be arranged in the same layer. When the plurality of pixels includes thin film transistor, the plurality of alignment marks may be formed of the same metal layer as the metal layer forming thin film transistor.

Abstract: A display device according to an embodiment of the present invention includes an anode electrode layer, a cathode electrode layer, a light emitting layer arranged between the anode electrode layer and the cathode electrode layer, a carrier transport layer and a carrier injection layer, which are arranged at least one of between the light emitting layer and the cathode electrode layer or between the light emitting layer and the anode electrode layer and a mixed layer arranged between the carrier transport layer and the carrier injection layer. The mixed layer is formed of a mixture of a material of the carrier transport layer and a material of the carrier injection layer. The mixed layer is formed so that a percentage of the material of the carrier injection layer in the mixture gradually increases in a direction from the carrier transport layer toward the carrier injection layer.
