Title:
【発明の名称】有機薄膜EL素子
Document Type and Number:
Japanese Patent JP2776040
Kind Code:
B2
Abstract:
PURPOSE:To obtain an organic membranous EL element which is hardly deteriorated even in the air by providing a sealing layer consisting of a metal oxide, a metal fluoride, or a metal sulfide, on the surface of an element at the cathode side. CONSTITUTION:An organic membranous electro-luminescence(EL) element is composed by laminating at least an anode 2, a positive hole pouring and transport layer 3, an organic electron transport luminous layer 4, and a cathode 5, or at least an anode 2, a positive hole pouring and transport layer 3, an organic luminous layer, an electron pouring and transport layer, and a cathode 5, in this order, on a substrate 1. A sealing layer 6 which consists of a metal oxide, a metal fluoride, or a metal sulfide is provided on the element. By the sealing layer 6, the organic membranous EL element is sealed airtight, being hardly deteriorated even in the air, and a long service life can be realized.
