Patent ID: 8648976

Claim:
A manufacturing method of a display device including, in an outside region surrounding a display region comprised of an assembly of pixels, a drive unit for supplying the pixels with a drive signal and an electrode terminal for inputting a control signal from the outside to the drive unit, the method comprising: in forming a plurality of thin film transistors of the drive unit: forming a first wiring that is connected to gate electrodes of the thin film transistors to cause the thin film transistors to perform a generating operation of the drive signal and forming a second wiring that connects the gate electrodes of the thin film transistors adjacent to one another, to provide a series connection between the gate electrodes of adjacent thin film transistors when the second wiring is uncut, in a forming region of the drive unit, said second wiring being formed in the same layer as the first wiring; and cutting the second wiring to disrupt the series connection of the gate electrodes of adjacent thin film transistors by the second wiring after forming the thin film transistors in the outside region of the display region.
