Description

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

  Color filters are widely used for image sensors, liquid crystal display devices, and the like, and their application range is rapidly expanding. Color filters used in color liquid crystal display devices and image sensors are usually spin-coated with a colored photosensitive resin composition containing a colorant corresponding to each of red, green and blue colors on a substrate on which a black matrix is patterned. After coating uniformly, the coating film formed by heating and drying (hereinafter sometimes referred to as pre-baking) is exposed and developed, and further heat-cured (hereinafter also referred to as post-baking) as necessary. It is manufactured by repeating the operation for each color to form pixels of each color.

  The colored photosensitive resin composition is a photosensitive resin composition colored with a colorant, and is useful as a material for forming a colored pattern constituting a color filter. Here, the color filter is an optical element that is built in the color liquid crystal display device and used to color the display image or is built in the image pickup device and used to acquire the color image.

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

  In order to realize these, application of dyes is being studied. However, in general, there are many problems that reliability and contrast are lowered as compared with the case where a pigment is applied.

  Korean Published Patent No. 10-2015-0101934 relates to a coloring composition containing a colorant and a polymerizable compound, and the colorant contains a polymer having a portion that emits fluorescence and a portion that absorbs the corresponding fluorescence, thereby providing heat resistance. A colored composition suitable for forming a colored cured film having high contrast while having excellent properties can be provided.

  Korean Patent No. 10-2014-0115990 is a coloring composition comprising a colorant comprising at least one compound selected from the group consisting of xanthene compounds, polymethine compounds, coumarin compounds and perylene compounds, a binder resin and a polymerizable compound. The present invention 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 prior art may be disadvantageous in luminance and reliability due to the color unique to transition metals and anthraquinones.
