PROBLEM TO BE SOLVED: To provide an inorganic EL display device of passive matrix drive system wherein the service life of an element can be prolonged even if it is increased in precision. SOLUTION: This organic EL display is provided with a first electrode 4, an organic EL emission layer 5 and a second electrode 6 which are arranged on a substrate 1. In the first electrode 4, a plurality of first wires 2 are laminated through insulating layers 3 in between and divided into a plurality of areas 7-10, the first wires 2 of the top layer of the inner areas 8, 9 are sequentially connected with the first wires 2 of the lower layer of the areas 7, 10 adjacent outside from central areas 8, 9 to outer areas 7, 10 and drawn outside of an arranging range of the organic EL emission layer 5 with the first wires 2 of the top layer of the outside areas 7, 10. Since the first electrode 4 has a multilayer structure, the number of partitions of a display screen can be increased and simultaneously driven and an emission time per pixel can be prolonged. Thus, the current density can be reduced for suppressing material deterioration to prolong the service life of the element. COPYRIGHT: (C)2006,JPO&NCIPI
