Patent ID: 7897216

Claim:
A method for manufacturing an electro-optic device including thin-film transistors each having an electrically conductive organic film, a gate insulating film formed on the electrically conductive film, and a gate electrode formed on the gate insulating film, the method comprising: providing a substrate; providing a pixel electrode on the substrate; providing a data line on the substrate, the data line being separated from the pixel electrode; disposing a solution containing an electrically conductive organic material in a first region and in a second region, the first region being a region located between the pixel electrode and the data line and overlapping a portion of the pixel electrode and a portion of the data line, the second region being a region located outside the first region where the solution is undesirably disposed; drying the solution disposed in the first region and in the second region to form the electrically conductive organic film in the first region and in the second region; forming the gate insulating film on the pixel electrode, the data line, and the electrically conductive organic film disposed in the first region and the second region; forming the gate electrode on the gate insulating film over the portion of the electrically conductive organic film disposed in the first region; and irradiating the gate electrode and the electrically conductive organic film formed in the second region with light to decrease the electrical conductivity of the electrically conductive organic film formed in the second region; wherein the gate electrode prevents the portion of the electrically conductive organic film formed in the first region from being irradiated by the light.
