PROBLEM TO BE SOLVED: To provide a pattern forming method which eliminates streaky unevenness in a thin-film pattern formed by jetting droplets, due to differences between individual nozzles, a droplet jetting apparatus and an electro-optical apparatus. SOLUTION: A head driving circuit inputs wave signals for a deep color and those for a light color alternately into each picture element of piezoelectric elements corresponding to a group Cmn of picture elements of the (odd-number)-th row. When inputting wave signals for a deep color into piezoelectric elements corresponding to a group Cmn of picture elements of the (odd-number)-th row, the circuit inputs wave signals for a light color into piezoelectric elements corresponding to a group Cmn of picture elements of the (even-number)-th row. When inputting wave signals for a light color into piezoelectric elements corresponding to a group Cmn of picture elements of the (odd-number)-th row, the circuit inputs wave signals for a deep color into piezoelectric elements corresponding to a group Cmn of picture elements of the (even-number)-th row.
