Water-absorbing agent for organic EL device and organic EL device |
摘要 |
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. The UV rays-curable type water-capturing agent can be formed in a desired thickness and pattern by applying it and irradiating with UV-rays, thereby making it possible to produce a low-profile organic EL device in large quantities with a high degree of reliability and without damaging the organic layer which is not resistant to water.
