Description

technical field

[0001] The invention relates to a negative low temperature curable photosensitive resin composition. More specifically, according to the present invention, it relates to a low-temperature curable photosensitive resin composition that has excellent curing reactivity even under low temperature conditions, can form a pattern with excellent reliability (adhesion), and is excellent in chemical resistance. Background technique

[0002] In the display field, the low-temperature-curable photosensitive resin composition is used to form a photocurable pattern of an insulating film, a protective film, and the like. Specifically, the low-temperature curable photosensitive resin composition is selectively exposed and developed through the photolithography process to obtain the desired photocured pattern. In order to improve the process yield in this process, a photosensitive resin with high sensitivity is required. combination.

[0003] The low-temperature curable photo...
