Abstract: A display device includes a transistor on a first region of an amorphous substrate and an LED on a second region different from the first region of the amorphous substrate. Each of the transistor and the LED includes a conductive alignment layer, a first semiconductor layer over the conductive alignment layer, and a second semiconductor layer over the first semiconductor layer. The conductive alignment layer, the first semiconductor layer, and the second semiconductor layer of the transistor are the same layer as the conductive alignment layer, the first semiconductor layer, and the second semiconductor layer of the LED, respectively. In the transistor, the first semiconductor layer is in contact with the second semiconductor layer. In the LED, a light emitting layer is provided between the first semiconductor layer and the second semiconductor layer.
