Patent ID: 8186808

Claim:
A droplet jetting apparatus using electrostatic force, comprising: a lower electrode unit in which a nozzle and a pole-type lower electrode positioned in the nozzle equipped in the upper part of a first substrate and an ink inflow channel equipped in the lower part of the first substrate and having a support member of the pole-type lower electrode therein are integrally formed; an upper electrode unit having an upper electrode formed on the top surface of a second substrate and an ink discharge hole formed by being penetrated to the upper electrode from the bottom surface of the second substrate; and a bonding layer for bonding the lower electrode unit and the upper electrode unit with each other so that the nozzle is vertically aligned with the ink discharge hole, when the electrostatic force generated by the potential difference between the lower electrode and the upper electrode is applied to ink supplied to the nozzle through the ink inflow channel, a meniscus being formed on the end of the nozzle and micro drops of ink being discharged from the edge of the meniscus through the ink discharge hole of the upper electrode unit.
