ABSTRACT:
A first positioning mark is formed at four corners of the outer side of the display area of a front substrate at the same step as the step of forming transparent electrodes. The first positioning marks are made of the same material as the material of transparent conductive films and formed in the same layer as a layer in which the transparent electrodes are formed. A second positioning mark is formed at four corners of the outer side of the display area of a back substrate at the same step as the step of forming partition walls. The second positioning marks are made of the same material as the material of glass layers containing white pigments and formed in the same layer as a layer in which the partition walls are formed. The positioning of the transparent display electrodes as well as the partition walls are directly carried out.
