[0153] Manufacture of color filter

[0154] Color filters were produced using the colored photosensitive resin compositions prepared in Examples 1 to 7 and Comparative Examples 1 to 5.

[0155] Each colored photosensitive resin composition was coated on a glass substrate by spin coating, and the resultant was placed on a hot plate and kept at a temperature of 100° C. for 3 minutes to form a thin film. Subsequently, a test photomask with a pattern whose transmittance changed in a stepwise manner from 1% to 100% and a line / space pattern of 1 μm to 50 μm was placed on the film at a distance of 100 μm from the test photomask UV rays are irradiated. Here, a 1KW high-pressure mercury vapor lamp containing all g, h, and i-rays was used as the ultraviolet light source at 100mJ / cm 2 The intensity of the irradiated light, without the use of special filters. The UV-irradiated film was developed by dipping in a developing solution of KOH aqueous solution at pH 10.5 for 2 minutes. T...

Abstract

The present invention relates to a colored photosensitive resin composition, a color filter manufactured using the composition, and an image display device comprising the color filter, the colored photosensitive resin composition comprising a colorant (A), a binder resin (B), photopolymerizable compound (C), photopolymerization initiator (D) and solvent (E); Wherein the colorant (A) includes C.I. Pigment Green 59, and one or more selected from pigments and dyes; And the photopolymerization initiator (D) includes one or more selected from phenyl-based oxime initiators and carbazole-based oxime initiators.

Description

technical field [0001] The present invention relates to a colored photosensitive resin composition, a colored pattern formed with the resin composition, a color filter comprising the colored pattern, and an image display device having the color filter. Background technique [0002] Color filters are widely used in various display devices such as imaging devices and liquid crystal display devices (LCDs), and the range of applications is rapidly increasing. The color filters used in such imaging devices, liquid crystal display devices, etc. are formed in three color patterns of red, green, and blue, or in three color patterns of yellow, magenta, and cyan. [0003] Each colored pattern of the color filter is generally formed using a colored photosensitive resin composition including a colorant such as a pigment or a dye, a binder resin, a photopolymerizable compound, a photopolymerization initiator, and a solvent. Processing of a colored pattern using the colored photosensitiv...
