Abstract:
1. An active matrix type display device comprising: a substrate; a first thin film transistor formed over the substrate; a pixel electrode electrically connected to the first thin film transistor formed over the substrate; a display medium adjacent to the pixel electrode, the display medium comprising an emissive material and capable of electrically changing luminous strength; a gate driver circuit operationally connected to a gate electrode of the first thin film transistor, the gate driver circuit including a dynamic type shift register, wherein the dynamic type shift register comprises a capacitor and a plurality of second thin film transistors formed over the substrate, wherein all of the first thin film transistor and the plurality of second thin film transistors have a same conductivity type, and wherein all of the first thin film transistor and the plurality of second thin film transistors are of n-channel type.
