Abstract
A thin film transistor array substrate and a display panel are provided. The thin film transistor array substrate includes a substrate, a thin film transistor, a scan line, a data line and a pixel electrode. The thin film transistor includes a semiconductor member, a gate electrode, a source electrode and a drain electrode. The source electrode and the drain electrode include a first extension portion and a second extension portion, respectively. The first extension portion and the second extension portion are configured to block light that is emitted toward an electron migration channel of the thin film transistor. Thus, external light emitting toward the electron migration channel can be prevented.
