Moreover, in the embodiment, after the adhesive layer 14A, the reflective layer 14B and the barrier layer 14C are formed on the planarizing layer 13 as a base layer, they are patterned in order from the barrier layer 14C to form the first electrode 14, so silver or the alloy including silver of the reflective layer 14B can be prevented from reacting with oxygen or sulfur in air by the barrier laye
