Abstract
An active device substrate including a substrate and an active device is provided. The active device includes a protrusion, a gate disposed on the protrusion, a semiconductor layer, a gate insulation layer disposed between the gate and the semiconductor layer, a first electrode and a second electrode electrically connected to the semiconductor layer. The protrusion has a first upper surface, a second upper surface, an inner surface and an outer surface. The inner surface and the first upper surface define a concave portion. The inner surface, the second upper surface and the outer surface define a convex portion. The semiconductor layer is disposed on the first upper surface, the inner surface, the second upper surface and the outer surface. The first electrode is disposed on at least one portion of the outer surface. The second electrode is disposed in the concave portion of the protrusion.
