The acrylic copolymer of a) above preferably has a polystyrene-equivalent weight average molecular weight (Mw) of 3000 to 30000. In the case of the organic insulating film having a polystyrene-reduced weight average molecular weight of less than 3000, there is a problem that the developability, the residual film rate, and the like are reduced or the pattern development, the heat resistance, and the like are deteriorated, and in the case of the interlayer insulating film having a polystyrene-reduced weight average molecular weight of more than 30000, there is a problem that the pattern development is deteriorated.

Further, after the development with the developer, the organic insulating film may be dried to form a pattern by removing unnecessary portions by washing with ultrapure water for 50 to 180 seconds, and the pattern may be selectively irradiated with light such as ultraviolet rays and then cured at a temperature of 150 to 250 ℃ for 30 to 90 minutes by a heating device such as an oven to obtain a final organic insulating film.
Further, the present invention can provide a display element including an organic insulating film formed by the above method for forming an organic insulating film of a display element.
The organic insulating film can be used as an organic insulating film for various displays, and is particularly suitable for a display for a COT liquid crystal display device having a white structure.
