Embodiment 1

[0138] Embodiment 1 (production of photosensitive resin composition)

[0139] With respect to 100 parts by weight of the copolymer whose solubility is increased by the photoacid generator of the following chemical formula 1-A, dissolve (Z)-4-methoxy-N-(toluenesulfonyloxy) as an oxime photoacid generator Base) 10 parts by weight of benzyl iminocyanamide, 2-[2-(furan-2-yl) vinyl]-4,6-bis(trichloromethyl)-same triazine-based photoacid generator 1 part by weight of oxazine, 0.5 part by weight of triethylamine as an organic base, and dissolved in propylene glycol monomethyl ether acetate so that the solid content of the above mixture is 20% by weight, and then utilize a 0.1 μm microporous filter Filtration to produce a photosensitive resin composition.

[0140]

Embodiment 2

[0142] When producing the photosensitive resin composition in the above-mentioned embodiment 1, use 2-[2-(furan-2-yl)vinyl]-4,6-bis(trichloromethyl)-s-triazine 3 parts by weight as triazine Except for the oxazine photoacid generator, the method similar to the said Example 1 was implemented and the photosensitive resin composition was manufactured.

Embodiment 3

[0144] When producing the photosensitive resin composition in the above-mentioned embodiment 1, use 2-[2-(3,4-dimethoxyphenyl)vinyl]-4,6-bis(trichloromethyl)-s-triazine Except having used 3 weight part as a triazine type photoacid generator, the method similar to said Example 1 was implemented, and the photosensitive resin composition was manufactured.

Abstract

A positive type photosensitive resin composition according to an embodiment of the present invention contains: a) a copolymer represented by chemical formula 1 below; b-1) an oxime-based photoacid generator; b-2) a triazine-based photoacid generator; c) an organic base; and d) a solvent. In chemical formula 1 above, R1 is any one of acetals and ketals, and x + y + z = 1.

Description

technical field [0001] The present invention relates to a positive photosensitive resin composition for display devices and a display device containing the same. Background technique [0002] In recent years, in liquid crystal display devices and organic light-emitting display devices, photosensitive organic insulating films are used to insulate wirings arranged between layers and to increase aperture ratios. [0003] As an interlayer insulating film for a liquid crystal display device, an acrylic insulating film is mainly used, but there is a problem related to outgassing due to a decrease in heat resistance. In addition, polyimide-based materials are used as interlayer insulating films or pixel defining films for organic light-emitting display devices, but there are problems such as sensitivity, adhesive force, permeability, and thermal discoloration resistance. [0004] In addition, in order to achieve high resolution, it is required to realize wiring with a fine line wi...
