There is a problem that a short circuit accident occurs due to a break in the light emitting organic layer. According to the present invention, the film thickness t3 is [(thickness t1 of the anode electrode 3−insulating film 6 between the anode electrodes 3 and between the anode electrodes 3 and the end portion on the outer side in the longitudinal direction of the anode electrode 3). Film thickness t 3) absolute value] <(thickness t2 of light-emitting organic layer 4), the dot-matrix organic LE provided with the insulating film 6 Since the D element 1 is used, the step of the transparent substrate 2 and the anode electrode 3 generated on the laying surface of the luminescent organic layer 4 that exceeds the film thickness of the luminescent organic layer 4 is caused by the insulating film 6. The problem is solved by relaxing within the range of the film thickness of the layer 4 to prevent the film surface of the light emitting organic layer 4 from being interrupted.
