ORGANIC ELECTROLUMINESCENCE ELEMENT

摘要

PROBLEM TO BE SOLVED: To provide an organic electroluminescence (EL) element using a graphene film for a transparent electrode that reduces a leak current and achieves high brightness.SOLUTION: The organic EL element is formed by laminating on a transparent resin substrate 101 a graphene film 102, a hole injection layer 103, an organic EL layer 104 and a negative electrode 105. By using a highly flat polyethylene terephthalate for the transparent resin substrate, a leak current is suppressed, and high brightness is achieved.SELECTED DRAWING: Figure 1
