Problems solved by technology

[0008] Especially when these photosensitive compositions are used as color filter protective films, if these highly polar organic solvents are contained, they will permeate into the color filter layer of the base, such as pigments or dyes contained in pixels. It is difficult to produce high-quality display elements due to the dissolution of coloring materials
[0009] There is Patent Document 4 in which a photosensitive composition is used in a protective film of a color filter. As a result of confirming the properties, the solvent resistance is not satisfactory, and further improvement is desired

Abstract

The invention relates to a photosensitive composition comprising the polyesteramide acid, a compound having the polymeric double bond, a photopolymerization initiator, an epoxy compound, and an epoxyhardener. The polyesteramide acid is obtained by reacting tetracarboxylic acid dianhydride, diamine, and polyhydroxy compound as the essentiality raw material component. A hardened film in which the transparency, the heat resistance, the resistance to solvents, the flatness and resolving potency are especially excellent can be obtained with the photosensitive composition of the invention. The hardened film is used for the electronic component etc.

Description

technical field [0001] The present invention relates to an insulating material for forming an electronic component, a passivation film, a buffer coating film, an interlayer insulating film, or a planarizing film in a semiconductor device, or an interlayer insulating film or a color filter in a display element. Photosensitive composition for protective film for sheet, etc. Furthermore, it is related with the electronic component containing the transparent film formed using the said photosensitive composition, and this film. Background technique [0002] In the manufacturing process of elements such as display elements, various chemical treatments such as organic solvents, acids, and alkali solutions are performed, or the surface is locally heated to a high temperature when forming a film of wiring electrodes by sputtering. Therefore, a surface protective film may be provided in order to prevent deterioration, damage, and deterioration of the surface of various elements. The...
