Description

TECHNICAL FIELD [0001] The present invention relates to a colored photosensitive resin composition, a color filter, and an image display device having the same. BACKGROUND ART [0002]

The present invention relates to a colored photosensitive resin composition, a color filter, and an image display device having the same.

BACKGROUND ART [0002] Color filters are widely used in imaging devices, liquid crystal display devices, and the like, and their application range is rapidly expanding. A color filter used for a color liquid crystal display device, an image pickup device, or the like is a device in which a colored photosensitive resin composition containing a coloring agent corresponding to each color of red, green and blue is uniformly applied by spin coating on a substrate on which a black matrix is patterned (Hereafter also referred to as post-baking) is repeated for each color to form each color, and the resulting coating film is exposed and developed by heating and drying Of the pixel.

The colored photosensitive resin composition is useful as a material for forming a colored pattern constituting a color filter as a colored photosensitive resin composition containing a coloring agent. Here, the color filter is an optical element which is built in a color liquid crystal display device and is used for coloring a display image or embedded in an image pickup device and used for obtaining a color image.

In addition, in order to save power of a color liquid crystal display, a color filter having a higher luminance is required. In general, a color filter tends to have a higher luminance when the film thickness is thinner. At this time, it is necessary to realize a high pigment concentration in order to ensure high color reproduction. However, the high concentration of the pigment lowers the storage stability and coatability of the resist composition, making it difficult to produce a color filter having sufficient performance.

Application of dyes has been studied to realize these. However, in general, there are many cases in which reliability and contrast are lowered in case of applying a pigment.

Korean Patent Laid-Open No. 10-2015-0101934 relates to a coloring composition comprising a colorant and a polymerizable compound, wherein the colorant comprises a polymer having a site that fluoresces and a site that absorbs the fluorescence, And a colored composition suitable for forming a colored cured film of high contrast can be provided.

Korean Patent Laid-Open Publication No. 10-2014-0115990 discloses a composition comprising a colorant, a binder resin and a polymerizable compound comprising at least one compound selected from the group consisting of a xanthene compound, a polymethine compound, a coumarin compound and a perylene compound As a coloring composition, it relates to a coloring composition further comprising a transition metal compound, and can provide a coloring composition preferable for forming a colored cured film having a high contrast.

However, the conventional techniques described above may be disadvantageous in terms of brightness and reliability due to the inherent color of the transition metal or anthraquinone.
