Abstract

Provided are polyimide precursor composition including a polyimide precursor including a siloxane structure, and inorganic particles, and an optical multilayer structure including a structure in which a polyimide shatterproof layer formed using the composition is formed on a substrate. The optical multilayer structure according to one implementation is less curled to minimize substrate bending and has significantly improved surface hardness, and thus, has excellent mechanical properties.
