ABSTRACT:
A bank for defining the regions in which pixels are formed has a stacked structure including: a base layer on the low level which also serves as an interlayer insulating film between the pixel forming regions; a middle bank layer on the middle level which serves to improve the fixation of an organic compound material (i.e., improve the uniformity of the film thickness of a positive hole transporting layer and an electron-transporting light emitting layer) in forming an organic EL layer; and a bank metal layer on the upper level which is made of a conductive material and serves also as a common voltage line (cathode line).
