AI Technical Summary

Problems solved by technology

Although this organic EL element does not produce the above-mentioned problems when the polishing process is carried out, compared with the alignment film that has carried out the polishing process, it is not easy to carry out the orientation of the light-emitting layer by light irradiation, because the orientation of the light-emitting body layer needs enough time. Light exposure

In addition, with respect to the heat load during manufacture or use, the luminous efficiency is lower than before the heat load
