Method for manufacturing display device with electrode having frame shape
View Patent ↗When a conductive layer is formed, a first liquid composition containing a conductive material is applied on an outer side of a pattern that is desired to be formed (corresponding to a contour or an edge portion of a pattern), and a first conductive layer (insulating layer) having a frame-shape is formed. A second liquid composition containing a conductive material is applied so as to fill a space inside the first conductive layer having a frame-shape, whereby a second conductive layer is formed. The first conductive layer and the second conductive layer are formed so as to be in contact with each other, and the first conductive layer is formed so as to surround the second conductive layer. Therefore, the first conductive layer and the second conductive layer can be used as one continuous conductive layer.
