Abstract
A thin film transistor array panel includes a substrate, an insulation layer, a first semiconductor, and a second semiconductor. The insulation layer is disposed on the substrate and includes a stepped portion. The first semiconductor is disposed on the insulation layer. The second semiconductor is disposed on the insulation layer and includes a semiconductor material different than the first semiconductor. The stepped portion is spaced apart from an edge of the first semiconductor.
