Abstract

A thin film transistor includes a base, a first electrode, an active pattern, a gate insulating layer, a gate and a second electrode. The active pattern includes a first semiconductor pattern, a second semiconductor pattern and a third semiconductor pattern. A material of one of the first semiconductor pattern and the third semiconductor pattern includes a semiconductor material and N-type doped ions, and a material of another of the first semiconductor pattern and the third semiconductor pattern includes the semiconductor material and P-type doped ions. An orthogonal projection of the gate on the base is non-overlapping with an orthogonal projection of the active pattern on the base.
