ABSTRACT:
A display panel integrated with EL can be obtained by printing EL at the back of a light permeable substrate, and covering the front surface of the substrate and the rearface of EL with a moisture proof film for insulating and protecting the EL from the surrounding atmosphere. Alternatively, the film may cover the substrate and EL entirely. An indication mark is printed at the surface of the moisture proof film or the light permeable substrate. The light permeable front electrode, the light emission layer and the back electrode are successively printed to the rearface of the light permeable substrate. If the indication mark is printed on the surface of the substrate, the attenuation of decay of the light emission from the emission layer can be suppressed and the brightness of the display mark improved by not forming the insulation layer at the back of the substrate. Alternatively, by forming the insulation layer at the back of the substrate, the entire thickness and the weight of the display panel can be decreased and the production step simplified.
