Classification: CPC H | IPC H

Claim 1:
2. The array substrate of claim 1, wherein the driving transistor is a thin film transistor comprising: a metal conductive pattern layer disposed on a base substrate; and an interlayer insulating layer, a metal oxide layer, a gate insulating layer, and the gate electrode, which are sequentially disposed on the base substrate having the metal conductive pattern layer;
wherein the metal conductive pattern layer includes: a light shielding pattern, a source signal line, and/or the drain signal line;
the metal oxide layer includes the source electrode, the drain electrode, and an active layer between the source electrode and the drain electrode and being in direct contact with the source electrode and the drain electrode;
an orthographic projection of the active layer on the base substrate has an overlapping region with an orthographic projection of the light shielding pattern on the base substrate; and
the source electrode extends through the interlayer insulating layer to connect to the source signal line, and/or the drain electrode extends through the interlayer insulating layer to connect to the drain signal line.
