Abstract: A water-capturing or drying agent placed in a hermetically sealed field light emission device for maintaining stable light emission of the light emission device not susceptible to moisture and oxygen for long period of time. The drying agent comprises a compound of polymer formed by bonding M constituting a plurality of organometallic compounds wherein M is a trivalent metal atom with an oxygen molecule. The drying agent is placed in the hermetically sealed container, thereby protecting the field light emission device from being adversely affected by damage from trace amounts of moisture permeating from outside the hermetically sealed container and/or adhered to the inner surface thereof.

Abstract: A thin-profile organic EL device with a high degree of reliability is provided. The anode, the organic layer and the light transmissible-type cathode are laminated on the substrate and the inorganic water-barrier layer are laminated thereon, and then a UV rays-curable type water-capturing agent comprising a UV rays-curing agent and a water-absorbing agent is cured to bond to the sealing substrate instead of an adhesive layer. The UV rays-curing agent comprises an acrylic monomer, initiator and accelerator. The UV rays-curable type sealing agent is placed to the outer peripheral portion of the UV rays-curable type water-capturing agent to be cured. The emission of the organic layer is transmitted upward via the cathode, UV rays-curable type water-capturing agent and the sealing substrate.

Abstract: An organic EL device capable of ensuring reliable and easy insulation between electrodes during patterning of the electrodes. The organic EL device includes an organic EL layer including a luminous layer and arranged between anodes and cathodes, as well as electrode separation sections arranged so as to separate the anodes from each other while insulating them from each other. The electrode separation sections each include a plurality of insulating ribs juxtaposed to each other at predetermined intervals and arranged on the anodes or in proximity to a periphery of the,anodes. This permits the interval between the ribs juxtaposed to each other to prevent the material for the second electrodes from advancing through the top surface of the ribs to the side surface thereof, to thereby ensure positive insulation between the second electrodes.

Abstract: An organic electroluminescent display device capable of permitting upper electrodes of a fine pattern to be formed and exhibiting increased durability. Ribs are spaced at predetermined intervals on transparent electrodes arranged in the form of a film on a lower transparent substrate. An organic layer is formed between each adjacent two of the ribs and an upper electrode is deposited all over the transparent electrodes. A portion of the upper electrode formed on each of the ribs is removed by scraping, rubbing or the like, resulting in the upper electrode being formed on only each of the organic layers. A cap layer may be provided on the upper electrode as required.
