REDUNDANCY SHIFT REGISTER CIRCUIT FOR DRIVER CIRCUIT IN ACTIVE MATRIX TYPE LIQUID CRYSTAL DISPLAY DEVICE |
摘要 |
An active matrix display device comprises a substrate having an insulating surface, a plurality of pixel electrodes arranged in a matrix form over the substrate, and a plurality of switching elements operationally connected to the pixel electrodes. Each of the switching elements further comprise a thin film transistor. The display device further includes a display medium comprising an emissive material that is capable of electrically changing luminous strength disposed at each of the pixel electrodes, and a driver circuit that includes a plurality of thin film transistors for driving the plurality of switching elements. Each of the plurality of thin film transistors comprise a crystallized semiconductor layer, a gate insulating film adjacent to the crystallized semiconductor layer and a gate electrode adjacent to the gate insulating film.
