Estimating the term…
A cap surrounding projection is provided on an outer periphery of a light transmitting cap substrate simultaneously with pixel separation banks, and a surrounding recess is formed in a position, opposed to the cap surrounding, projection, on a substrate provided with emitter elements, the projection and the recess being joined through a sealant with an absorbent arranged therein. With such construction, it becomes possible to efficiently take out light from an emitting layer and to highly accurately seal the substrate provided with the emitter elements and the light transmitting cap substrate, thus realizing an organic electro-luminescence device of high reliability.
An organic electro-luminescence device comprising an emitter element forming substrate, a cap substrate, a cap outer-periphery surrounding rib, and a sealant, and wherein emitter element are formed on the emitter element forming substrate to have at least an emitting layer, which is formed in pixel separation banks, interposed by anode electrodes and cathode electrodes, and the emitter element forming substrate and the cap substrate are joined together through the sealant so that the emitter element are arranged inside the cap outer-periphery surrounding rib formed on an outer periphery of the cap substrate in a picture-frame manner.
A method of manufacturing an organic electro-luminescence device, comprising the steps of:
