| 摘要 |
<p>The present invention relates to a protection material for an organic electroluminescence device for simplifying a process, improving a bonding force, and having a thin thickness. It comprises a block copolymer which is a covalent bond of polymer having hydrophobic and hydrophilic functional groups; and an inorganic precursor of metal Alkoxide mixed with the block copolymer. The polymer having hydrophobic and hydrophilic functional groups is mixed with a volume ratio of 0.4:0.6-0.6:0.4 and has a plate shape.</p> |
