摘要

PURPOSE: A filler is provided to have excellent adhesion with various elements while maintaining other required properties, thereby using for various optoelectronic devices effectively. CONSTITUTION: Filler comprises hydrolyzable group, or an olefin resin having a reactive group which is hydrolyzed material of the hydrolyzable group, and the 90° peering force measured after being bonded to a glass substrate by compressing for 10 minutes in the condition of 150 °C by using a vacuum laminator is 70N/15mm. the olefin resin is a copolymer containing α-olefin, and an unsaturated silane compound in chemical formula 1, or a graft copolymer in which the silane compound is grafted to an olefin resin.
