Abstract: A display panel includes a base substrate, a first transistor disposed on the base substrate and including a first semiconductor pattern layer and a first gate electrode, and a light emitting element disposed on the first transistor and electrically connected to the first transistor. The first semiconductor pattern layer may include a first active pattern layer disposed on the base substrate, a first drain contacting the first active pattern layer, and a first source contacting the first active pattern layer and spaced apart from the first drain. A first spaced region between the first drain and the first source may be defined as a first channel region of the first active pattern layer, and the first gate electrode may overlap the first channel region.
