Abstract
Abstract To provide a process of successively forming from an EL layer, a cathode, a barrier layer and a cover layer in the same multi-chamber. By using a same film deposition method to form the EL layer and the cover layer, as shown in FIG. 1 A, the EL layer, the cathode, the barrier layer, and the cover layer can be formed in the same multi-chamber in succession. Thus, as shown in FIG. 1 B, a sealed structure of an EL element can be formed.
