P‐6.4: Black photoresist for flexible film with broad taper angle, high OD and very high electric resistivity

Abstract

This paper introduces black photoresist specially designed for making black layers on flexible film. Flexibility, broad tapered profile, high optical density (OD) and high electric resistance are achieved. The flexibility is suitable for film type devices and the high electric resistivity is likely suitable for black matrix (BM) and micro light emitted diode (LED).
