Manufacturing method of electrode structure of base plate

The invention provides a manufacturing method of an electrode structure of a base plate. The manufacturing method of the electrode structure of the base plate comprises the following steps: providing the base plate on which an electrode region defined by a patterned metal layer; coating the patterned metal layer by using a protective glue cover; forming an electrode layer in the electrode region; and implementing a filling step so as to deposit nano oxide on the electrode layer so that the nano oxide is filled in the whole electrode region.
