ポジティブ型感光性樹脂組成物、これから形成された絶縁膜および有機発光素子、並びにポジティブ型感光性樹脂組成物の製造方法

摘要

This invention relates to a positive-type photosensitive resin composition which includes an alkali soluble polyimide resin, a diazide-based photosensitive compound and a sensitivity enhancer, and in which the use of a polyimide resin wherein the degree of imidization of imidized polyimide resin is 50˜75% exhibits a light transmittance of 95% or more in the visible light wavelength range (400˜650 nm) as well as high developability in a patterning process, and to an insulating film and an OLED formed using the same.
