摘要

An organic luminescence device including organic layers disposed between an anode and a cathode is produced through a process including: a step of forming a first organic layer over an anode already formed on a first substrate; a step of forming a second organic layer comprising an identical material forming the first organic layer over a cathode already formed on a second substrate; and a combining step of disposing the first and second organic layers opposite to each other and applying the first and second organic layer to each other under pressure, followed by baking, to form a laminate organic luminescence device. A step of pre-baking at least one of the first and second organic layers is preferably included prior to the combining step. As a result, the organic layers in the luminescence device can be formed free from binders and yet in a good adhesion therebetween.
