Abstract: PURPOSE: A variable liquid lens array and a manufacturing method thereof are provided to reduce energy consumption for obtaining a flat surface in the initial stage. CONSTITUTION: A variable liquid lens array(1) comprises a first fluid(25), a second fluid(30), a first electrode(20), a second electrode(35), partitions(15), and cells(18). The partitions are arranged on a substrate and have fluid flow paths and define the cells. The first fluid is contained in the cells and the second fluid is located on the top of the first fluid. The first electrode is provided on the side of the partitions and the second electrode is arranged separately from the partitions. When voltage is applied to the first and second electrodes, the boundary surface between the first and second fluids changes in shape.
