Summary:PROBLEM TO BE SOLVED: To provide an organic EL display device that is capable of preventing generation of cracks at a glass substrate or separation of an adhesive surface due to contraction accompanying hardening of an adhesive substance when lead-out electrodes are exposed to adhere a sealing lid to the glass substrate. SOLUTION: In this organic EL display device 30, a main organic EL display body 8 is formed on a glass substrate 5. An organic EL element is laminated such that lead-out electrodes 4, 4a are led out to an edge of a transparent substrate 5 from the organic EL display body 8. Adhesive areas 32 are widened at outer circumference of the organic EL display body 8 by traversing the lead-out electrodes 4, 4a. In the adhesive areas 32, dummy patterns 31 (interposing member) are laminated at a range which is not traversed by the lead-out electrodes 4, 4a. A sealing lid 7 is adhered to the adhesive areas 32 which is flattened entirely.
