POSITIVE PHOTOSENSITIVE POLYIMIDE COMPOSITION

摘要

A positive photosensitive polyimide composition, and an organic insulating layer of dual layer for an organic light emitting device using the composition are provided to control a taper angle and outgassing and to improve adhesion, water repellency and storage stability. A positive photosensitive polyimide composition comprises a polyimide comprising a repeating unit represented by the formula 1; a polyamic acid comprising a repeating unit represented by the formula 2; and a photoactive compound, wherein m is an integer of 1-30; n is an integer of 1-10; X is a tetravalent aromatic organic group; Y1 is a divalent aromatic organic group; Y2 is a divalent silicon-based substituent; and l is an integer of 1-20.
