Pattern electrode structure for electro-wetting apparatus

A pattern electrode structure for an electro-wetting apparatus, which is stacked between a base material and a dielectric layer of the electro-wetting apparatus, the pattern electrode structure comprising:

• a plurality of branch electrodes formed in a direction perpendicular to an arbitrary plane perpendicular to a plane formed by the pattern electrode structure to be spaced from each other at regular intervals;
• and
• a plurality of sub-branch electrodes formed to extend from the plurality of branch electrodes by a predetermined length in an inclined direction,
• wherein, among the plurality of sub-branch electrodes, a sub-branch electrode extending from one branch electrode among the plurality of branch electrodes is formed to be spaced from a sub-branch electrode extending from an adjacent branch electrode by a predetermined distance,
• wherein the sub-branch electrode extending from the one branch electrode among the plurality of branch electrodes is placed between sub-branch electrodes extending from the adjacent branch electrode,
• wherein the inclined direction of the plurality of sub-branch electrodes extended from same side of the plurality of branch electrodes is same, and
• wherein the sub-branch electrode extending from the adjacent branch electrode is arranged between two sub-branch electrodes extending from one branch electrode among the plurality of branch electrodes and arranged vertically adjacent to each other.
