Abstract
A manufacturing method for a liquid lens device includes the steps of: preparing a body having a liquid chamber, a conductive first liquid stored in the liquid chamber, an insulating second liquid stored in the liquid chamber, and a hollow electrode pipe for making the communication between the inside and the outside of the liquid chamber, the liquid chamber being defined by a first transparent substrate on which an electrode layer is formed, a second transparent substrate opposed to the first transparent substrate, and an annular sealing member interposed between the first transparent substrate and the second transparent substrate; applying pressure to the first and second transparent substrates to thereby compress the sealing member and discharge the first liquid from the second end of the hollow electrode pipe; and closing the second end of the hollow electrode pipe.
