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.
