Abstract
The present invention relates to a method for manufacturing an electrowetting element, in which a first liquid material and a second liquid material having a surface energy which is lower than that of the first liquid material, which are not mixed together, are provided in a cell formed between a first substrate and a second substrate placed as facing; at least one of the first liquid material and the second liquid material is gelated or altered to have high viscosity; and the shape of the interface between the first liquid material and the second liquid material is changed by applying voltage in the cell. The method includes a step of stimulating at least one of the first liquid material and the second liquid material which is gelated or altered to have high viscosity, to alter one of the first liquid material and the second liquid material to have low viscosity. According to the present invention, an electrowetting element can be manufactured easily, and the electrowetting element manufactured by the present invention does not show increase of applied voltage, delay of operation and the like.
