ABSTRACT:
An object of the invention is to reduce the manufacturing cost of EL display devices and electronic devices incorporating the EL display devices.An EL material is formed by printing in an active matrix EL display device. Relief printing or screen printing may be used as the method of printing. Manufacturing steps of the EL layer is therefore simplified and reduction of manufacturing cost is devised.
