1. An organic light-emitting diode (OLED) display panel, comprising:
a base layer;
an active layer disposed on the base layer, wherein the active layer comprises a channel portion, a source contact portion and a first electrode disposed on opposite sides of the channel portion, and an anode connected to the first electrode;
a gate insulating layer disposed on the channel portion;
a first metal layer disposed on the gate insulating layer;
a second metal layer disposed above the first metal layer and comprising a second electrode connected to the source contact portion; and
an insulating layer disposed on the base layer and the active layer, wherein the insulating layer, the first metal layer, and the second metal layer are stacked, and an opening is defined in the insulating layer corresponding to the anode.
