Abstract
In an electroluminescence panel, first and second charge injection refraining layers are formed between transparent electrodes and a first insulating layer and between back electrodes and a second insulating layer, respectively, and first and second charge injecting layers are formed between the first insulating layer and an emitting layer and between the second insulating layer and the emitting layer, respectively. The charge injection refraining layers suppress the injection of charges into the first and second insulating layers to enhance the ability of the panel to withstand the applied voltages, and the charge injecting layers inject a large quantity of charges into the emitting layer to increase the luminance. Further, the fabricating efficiency is not lowered.
