Patent ID: 7732003

Claim:
A method of forming a bank that partitions a predetermined area of a base member on the base member and forming a wiring pattern on the base member, the method comprising: radiating a first light to the base member over which a sublimation layer containing a sublimation material and a photothermal conversion layer are formed, the photothermal conversion layer being provided between the base member and the sublimation layer and containing a first photothermal conversion material that converts optical energy of the first light into a first thermal energy; sublimating the sublimation material to form the banks, the sublimation layer including a binder resin with sublimation pigment or dye dispersed within; arranging liquid droplets containing a wiring pattern forming material between the formed banks; and radiating a second light to the base member to generate a second thermal energy by the photothermal conversion layer to form the wiring pattern, the second thermal energy causing the wiring pattern forming material to exhibit conductivity.
