Abstract
An active device, a driving circuit structure, and a display panel are provided. The active device includes a gate, a gate insulation layer covering the gate, a semiconductor layer disposed above the gate, an etching stop layer disposed on the gate insulation layer and the semiconductor layer, a source, and a drain. The gate forms a meandering pattern on a substrate. The semiconductor layer has an area substantially defining a device region where the active device is. The etching stop layer has a first contact opening and a second contact opening. The first contact opening and the second contact opening separated from each other and both exposing the semiconductor layer. The source and the drain separated from each other are disposed on the etching stop layer and in contact with the semiconductor layer through the first contact opening and the second contact opening, respectively.
