Abstract:
1. A display device being provided with a display driving circuit including a dynamic shift register which includes a first MISTFT on a substrate surface, wherein: the dynamic shift register is comprised of a second MISTFT and a third MISTFT which use polycrystalline silicon as a semiconductor layer: the first MISTFT includes a gate electrode, a first electrode and a second electrode, wherein a voltage of the gate electrode is boosted by a voltage of the first electrode changing from low level to high level, the second MISTFT is connected between a ground level line and the gate electrode of the first MISTFT, and the third MISTFT is comprised such that the gate electrode of the first MISTFT is dropped to a ground level during a period other than a period in which a signal of high level is transmitted into the gate electrode of the first MISTFT.
