Abstract:
An electrowetting display device according to the present invention comprises a lower substrate, an upper substrate, and a fluid disposed between the lower substrate and the upper substrate. The lower substrate includes a base part, a lower electrode formed on the base part, an insulating layer covering the base part and the lower electrode, and a partition part defining a plurality of pixels by being disposed on the insulating layer. The upper substrate includes a panel part and an upper electrode formed on the lower part of the panel part. The partition part includes a plurality of partitions with a predetermined length, width, and height. An opening part in which the fluid can move is formed between the partitions.

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.
