Abstract: A display includes a pixel circuit. The pixel circuit includes a light emitting diode, a first transistor, a second transistor and a third transistor. The first transistor includes a first semiconductor layer. The first transistor has a first control terminal, a second terminal, and a third terminal electrically connected to the light emitting diode. The second transistor includes a second semiconductor layer, and is electrically connected to the third terminal. The third transistor is electrically connected to the first control terminal. A material of the first semiconductor layer is different from a material of the second semiconductor layer.
