ENCAPSULATION COMPOSITION, CURED LAYER AND ORGANIC LIGHT EMITTING DEVICE, LIQUID CRYSTAL DISPLAY, PLASMA DISPLAY DISPLAY AND SOLAR CELL

摘要

PURPOSE: A sealant composition is provided to have excellent light transmittance with blocking the inflow of moisture to an optical device, thereby using for double-side light emitting type display device. CONSTITUTION: A sealant composition comprises: a reaction product of a silicon compound in chemical formula 1, and an organic metal compound in chemical formula 2; a silicon cross-linking compound in chemical formula 3; and a catalyst. The content of the reaction product of silicon compound in chemical formula 1 and organic metal compound in chemical formula 2 is 60-95 weight% on the basis of total composition, and the content of the silicon cross-linking compound is 4-39.999 weight% on the basis of the total composition.
