Abstract
A display panel includes a base substrate, a third transistor and a fourth transistor. The third transistor and the fourth transistor are formed on the base substrate. The third transistor includes a sixth gate electrode, a third active layer, a third source electrode, and a third drain electrode. The third active layer includes an oxide semiconductor. The fourth transistor includes an eighth gate electrode, a fourth active layer, a fourth source electrode, and a fourth drain electrode. The fourth active layer includes another oxide semiconductor. Along a direction perpendicular to the base substrate, a distance between the sixth gate electrode and the third active layer is D. A channel region of the third transistor defined by the sixth gate electrode is a sixth channel region. A length of the sixth channel region is L. A sixth area S=L×D
