PHOTOSENSITIVE ORGANIC INSULATION COMPOSITION FOR AN OLED DEVICE

摘要

Polyimide or a precursor thereof expressed by Chemical Formula 1 or 2 and a photosensitive organic insulator composition having the same are disclosed. The polyimide or the precursor thereof is prepared from diamine including polyalkyleneoxide. The use of the photosensitive organic insulator composition can allow for low temperature curing and shorten a curing time, form a low taper angle, and implement a high sensitivity and high residual film. Also, since the photosensitive organic insulator composition, as a positive photosensitive composition, has excellent solubility with respect to an alkali solution of an exposed portion, the generation of impurity can be minimized.
