ABSTRACT:
A display panel drive circuit and a display panel are provided which are simple in structure but free from initial failure leading to impossibility to perform scanning. The display panel drive circuit of the present invention is structured such that thin film transistors constituting a signal input circuit connected to a circuit outside the display panel are formed in a structure having a dielectric breakdown strength higher than those of thin film transistors constituting other circuits. Specifically, countermeasures are taken by transistor formation in multi-gate structure, gate width broadening, resistance insertion between an input terminal and a transistor or the like. In the present invention, the circuit to which signals are externally inputted or thin film transistors of the same circuit is structured to withstand high voltage, thereby preventing the transistors from being deteriorated by high voltage and occurrence of initial failure while being simple in structure.
