A display device includes a first electrode, a second electrode, a third electrode, a lyophobic layer, a first liquid, and a second liquid, where the lyophobic layer is lyophobic to the second liquid. A method of driving the display device includes: providing a first potential difference between the first electrode and the third electrode to thereby cause the first liquid to begin moving toward the second electrode; providing a second potential difference between the second electrode and the third electrode while reducing the first potential difference to thereby cause the first liquid to move toward the first electrode; and removing the second potential difference to thereby cause the first liquid to slow down in its movement toward the first electrode or to stop in its movement toward the first electrode.

Electrowetting display device and driving method thereof

A sputtering device includes: a sputtering target; a substrate supporter facing the sputtering target and upon which a substrate is disposed; an anode mask between the sputtering target and the substrate which is on the substrate supporter; and a gas distribution member between the anode mask and the sputtering target, and including a plurality of gas distribution tubes separated from each other. Each gas distribution tube includes a plurality of discharge holes defined therein and through which gas is discharged to a vacuum chamber configured to receive the sputtering device.
