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