Patent ID: 7138304

Claim:
A production method for an active matrix substrate, comprising: a first step of forming gate wiring on a substrate; a second step of forming a gate insulating film on the gate wiring; a third step of stacking a semiconductor layer on the gate insulating film; a fourth step of forming a source electrode and a drain electrode on the gate insulating film; a fifth step of disposing an insulating material on the source electrode and the drain electrode; and a sixth step of forming a pixel electrode on the disposed insulating material, wherein a method for forming a thin film pattern comprises ejecting a plurality of liquid droplets of a function liquid at predetermined pitches along a groove formed between banks, wherein each of the predetermined pitches is larger than a diameter of the liquid droplets and the predetermined pitches are set so that adjacent liquid droplets coalesce with each other when wetting and spreading within the groove, wherein the width of the groove is smaller than a diameter of the liquid droplets, and wherein liquid-repellency higher than that of the groove is imparted to the bank is used at at least one step of the first step, the fourth step, and the sixth step.
