Abstract
An object of the present invention is to provide a method for manufacturing electrodes that can effectively suppress edge-curl when metal electrodes such as bus electrodes and data electrodes are patterned mainly by a photolithography method.In order to achieve the above object, in the manufacturing method in the present invention, an amount of undercut generated by difference in a degree of dissolution caused by developing solution is controlled, and baking is performed at a temperature such that glass in a protrusion formed at side edges becomes soft so as to touch a substrate by gravity. With such method for manufacturing, it becomes possible to make the side edges rounded whose curvature changes continuously.
