An organic EL structure body 2 is formed on a surface of a transparent substrate 1, and the EL structure body 2 is sealed by a metal airtight container 20. Circuit structure bodies such as an anode driver circuit 11 and a cathode driver circuit 12 are mounted on a part of the transparent substrate 1. These earth lines, for example, are commonly connected through conductors 21a and 21b. Therefore, the above-mentioned circuit structure bodies are mutually connected by the earth line of low impedance, so that an obstruction occurred in the EL display device under an earth line of high impedance can be suppressed.
