A display panel includes a light emitting element on a base layer, and a pixel driving circuit electrically connected to the light emitting element. The pixel driving circuit includes a first transistor including a first oxide semiconductor pattern and a second transistor including a second oxide semiconductor pattern. The first oxide semiconductor pattern includes a first channel region including a first oxide semiconductor layer and a second oxide semiconductor layer on the first oxide semiconductor layer, and the second oxide semiconductor pattern includes a second channel region including a single-layer oxide semiconductor layer.
