Embodiment 1

[0119] TiO 2 Filler (average particle size: 200nm), 2-hydroxy-3-phenoxypropyl acrylate as a photopolymerizable (meth)acrylic monomer, benzyl methacrylate (BZMA) / methacrylic acid as an alkali-soluble resin (MAA) / glycidyl methacrylate (GMA) copolymer, 2-methyl-1-[4-(methylthio)phenyl]-2-morpholinopropane-1- Ketone, and diethylene glycol monobutyl ether / propylene glycol monomethyl ether acetate mixed solvent as an organic solvent are added to the container in such a way that the weight ratio reaches 30:40:30:3:100 in sequence and stirred , after roughly mixing, further mixing was performed using a three-roll mill. This produces a homogeneously dispersed TiO 2 Filled photosensitive composition.

[0120] The above-mentioned BZMA / MAA / GMA copolymer is obtained by copolymerizing BZMA, MAA and GMA in a weight ratio of 75:16.8:8.2 (because GMA is a glycidyl compound of MAA, the weight ratio of BZMA to MAA is 75:25). copolymer. The BZMA / MAA / GMA copolymer had a weight average molecul...

Embodiment 2

[0128] make TiO 2 Filler, 2-hydroxy-3-phenoxypropyl acrylate, BZMA / MAA / GMA copolymer, 2-methyl-1-[4-(methylthio)phenyl]-2-morpholinopropane-1 - The weight ratio of ketone and diethylene glycol monobutyl ether / propylene glycol monomethyl ether acetate mixed solvent reaches 10: 50: 40: 3: 100 successively, except that, carry out the operation identical with embodiment 1 operation, thus producing a photosensitive composition and pattern. Table 1 summarizes the evaluation results of the composition and pattern of the obtained photosensitive composition.

Embodiment 3

[0130] As the photopolymerizable (meth)acrylic acid monomer, except that the methacrylic acid adduct of bisphenol A diglycidyl ether was used instead of 2-hydroxy-3-phenoxypropyl acrylate, proceed and implement A photosensitive composition and a pattern were manufactured by the same operation as in Example 1. Table 1 summarizes the evaluation results of the composition and pattern of the obtained photosensitive composition.

Abstract

Provided are: a photosensitive composition for forming a pattern that is used in a display device and has a light scattering function; a pattern; and a display device which has a pattern. This photosensitive composition for forming a pattern that is used in a display device and has a light scattering function contains a TiO2 filler, a photopolymerizable (meth)acrylic monomer, an alkali-soluble resin, a photopolymerization initiator and an organic solvent. The ratio of the TiO2 filler in the total mass of the TiO2 filler, the photopolymerizable (meth)acrylic monomer and the alkali-soluble resin is within the range of 10-35% by mass.

Description

[0001] This application is a divisional application, the filing date of the parent application is January 18, 2013, the international application number is PCT / JP2013 / 050883, the application number entering the Chinese national phase is 201380006593.6, and the invention name is "photosensitive composition , patterns and display devices with patterns”. technical field [0002] The present invention relates to a photosensitive composition for forming a pattern having a light-scattering function used in a display device, a pattern, and a display device having the pattern. Background technique [0003] Conventionally, a non-self-luminous full-color display device using a white light backlight is mainly composed of the backlight and a shutter. For example, a liquid crystal display device has a light source such as an LED or a cold cathode tube, a light guide plate and an optical sheet as a backlight, and a liquid crystal panel as a shutter. The liquid crystal panel includes two ...
