Patent ID: 7736955

Claim:
A method for manufacturing a display device comprising: sending a flexible substrate from a first roll in a wind-off side; forming a metal film over the flexible substrate by selectively discharging a composition including a conductive material over the flexible substrate from a plurality of discharge outlets arranged in a uniaxial direction, a timing and an amount of the composition which is discharged being controlled by a plurality of heads respectively having the discharge outlet; forming a mask pattern over the metal film by selectively discharging a composition including a high molecular weight resin over the metal film from a plurality of discharge outlets arranged in a uniaxial direction, a timing and an amount of the composition which is discharged being controlled by a plurality of heads respectively having the discharge outlet; forming a gate electrode by etching the metal film by changing a gas into plasma and selectively supplying the plasma from a plurality of discharging ports arranged in a uniaxial direction to the metal film, the plurality of discharging ports being controlled independently; removing the mask pattern after forming the gate electrode by changing a gas into plasma and selectively supplying the plasma from a plurality of discharging ports arranged in a uniaxial direction to the mask pattern, the plurality of discharging ports being controlled independently; forming a film over the gate electrode by changing a gas into plasma and selectively supplying the plasma over the gate electrode from a plurality of discharging ports arranged in a uniaxial direction, the plurality of discharging ports being controlled independently; and sending an opposing substrate from a second roll so that the opposing substrate is attached to the flexible substrate.
