Abstract

A display panel includes a base substrate, a first transistor and a second transistor. The first transistor and the second transistor are formed on the base substrate. The first transistor includes a first active layer, a first gate electrode, a first source electrode, and a first drain electrode. The first active layer includes silicon. The second transistor includes a second active layer, a second gate electrode, a second source electrode, and a second drain electrode. The second active layer includes an oxide semiconductor. A length of a channel region of the first transistor is L1. Along a direction perpendicular to the base substrate, a distance between the first gate electrode and the first active layer is D1. The first transistor further includes a third gate electrode. Along the direction perpendicular to the base substrate, a distance between the third gate electrode and the first active layer is D3, and D1<D3.
