Zusammenfassung:	A variable focus liquid lens using an electrohydrodynamic flow of a fluid is provided. The electrohydrodynamic liquid lens includes: a housing that forms a flow channel of a ring shape therein; a first liquid that occupies a portion of the flow channel; a second liquid that occupies the remaining portion of the flow channel and that maintains a separation state from the first liquid; and a control electrode that contacts the first liquid in the flow channel. At an interface in which the first liquid and the second liquid contact, a curvature is formed to function as a lens, and the control electrode causes an electrohydrodynamic flow of the first liquid, thereby changing a location of the interface.
