example 1

[0171] Example 1: Preparation of photosensitive resin composition

[0172] By adding about 100 parts by weight of the acrylic copolymer prepared in Synthesis Example 1, about 30 parts by weight of 4,4'-[1-[4-[1-[4-hydroxyl Phenyl]-1-methylethyl]phenyl]ethylene]bisphenol 1,2-naphthoquinonediazide-5-sulfonate was dissolved in triglyme so that the solidity of the mixture The content is about 20% by weight, and it is filtered using a Millipore filter with a pore size of about 0.1 μm.

example 2

[0174] A photosensitive resin composition was prepared by performing the same procedure as described in Example 1 except that diethylene glycol butyl methyl ether was used instead of triglyme.

example 3

[0176] A photosensitive resin composition was prepared by performing the same procedure as described in Example 1 except that triethylene glycol butyl methyl ether was used instead of triglyme.

Abstract

The invention provides a photosensitive resin composition, and a display device using the same. The photosensitive resin composition comprises about 10 wt % to about 50 wt % of a solute comprising about 100 parts by weight of an acryl-based copolymer and about 5 to about 100 parts by weight of a 1,2-quinonediazide compound; and a solvent comprising a glycol-based material having a boiling point of greater than about 190 DEG C., wherein the acryl-based copolymer is a copolymer of an unsaturated carbonic acid or an anhydride thereof, an epoxy group-containing unsaturated compound, and an olefin-based unsaturated compound.

Description

[0001] This application claims the benefit of Korean Patent Application No. 10-2013-0021234 filed on February 27, 2013 and Korean Patent Application No. 10-2013-0127433 filed on October 24, 2013, which are incorporated by reference The entire content of the Korean patent application is incorporated herein. technical field [0002] The present disclosure herein relates to a photosensitive resin composition, a display device using the photosensitive resin composition, and a method of manufacturing the display device. The display device includes an organic planarization layer obtained by curing a photosensitive resin composition.
