SPONTANEOUSLY LUMINESCENT DEVICE

摘要

PROBLEM TO BE SOLVED: To solve problems of an organic electroluminescent(EL) device that is easily deteriorated by slight acid and heating and prompts oxidization. SOLUTION: In an active matrix type organic EL display device in which an organic EL layer is formed on a insulation gate type electric field effect transistor being formed on a mono crystal semiconductor substrate, the mono crystal semiconductor substrate is maintained in gaps formed by billers for adhering to a die plate and a lid plate formed of insulation substance and inert gas and desiccant are filled in the gaps.
