  • Patent number: 7176624
    Abstract: An organic EL display panel has a multi-layered structure in which a first electrode and a second electrode are formed on a transparent panel and an organic EL layer is formed between the first and second electrodes. A method for sealing the organic EL display panel includes the steps of forming a buffer layer of an organic matter such as silicon oxide and silicon nitride on the transparent panel, and locating a shield cover on the buffer layer. Thus, adhesive strength between the panel and an adhesive is enhanced to prevent external humidity and oxygen from being permeated into the panel, thereby increasing life span of the display.
