Abstract

This specification provides a photosensitive resin composition, a photosensitive material, a color filter, and a display device.

Description

Photosensitive resin composition, photosensitive material, color filter and display device {PHOTORESIST RESIN COMPOSITION, PHOTORESIST, COLOR FILTER AND DISPLAY DEVICE}

This specification relates to photosensitive resin compositions, photosensitive materials, color filters, and display devices.

Currently, a pigment dispersion method using pigment as a colorant is generally applied to implement a color filter. However, in the case of a pigment dispersion, the pigment exists in the form of particles and not only scatters light, but also the surface area of the pigment increases rapidly due to the miniaturization of the pigment, which deteriorates the dispersion stability and generates non-uniform pigment particles. Therefore, in order to achieve the high brightness, high contrast ratio, and high resolution that are recently required, the use of dyes instead of pigments has recently been considered.

In general, dyes have the advantage of higher permeability compared to pigments. However, it has the disadvantage of lacking heat resistance compared to pigments. In addition, it has the disadvantage of poor chemical resistance due to its good solubility in organic solvents compared to existing pigments.

To implement a color filter, a pigment dispersion method using pigment as a colorant is generally applied.

An exemplary embodiment of the present specification provides a photosensitive material including the photosensitive resin composition.

More specifically, the photosensitive resin composition of the present specification is applied on a substrate by an appropriate method and cured to form a photosensitive material in the form of a thin film or pattern.

The application method is not particularly limited, but spray method, roll coating method, spin coating method, etc. can be used, and spin coating method is generally widely used. Additionally, after forming the coating film, in some cases, some residual solvent may be removed under reduced pressure.

Light sources for curing the photosensitive resin composition according to the present specification include, for example, a mercury vapor arc (arc), carbon arc, Xe arc, etc. that emit light with a wavelength of 250 nm to 450 nm, but are not necessarily limited thereto.

The photosensitive resin composition according to the present specification is a pigment-dispersed photoresist for manufacturing a color filter for a thin film transistor liquid crystal display (TFT LCD), a photoresist for forming a black matrix of a thin film transistor liquid crystal display (TFT LCD), or an organic light emitting diode. , photosensitive material for forming an overcoat layer, column spacer photosensitive material, photocurable paint, photocurable ink, photocurable adhesive, printing plate, photosensitive material for printed wiring board, photosensitive material for plasma display panel (PDP), etc. There are no particular restrictions.

One embodiment of the present specification provides a color filter including the photosensitive material.

The color filter may include a polymer containing a triarylmethane dye monomer and a (meth)acrylic acid monomer; A binder resin containing a structure represented by the following formula (1); multifunctional monomer; photoinitiator; and a solvent. A color filter can be formed by applying the photosensitive resin composition on a substrate to form a coating film, and exposing, developing, and curing the coating film.

The substrate may be a glass plate, a silicon wafer, or a plastic plate such as polyethersulfone (PES) or polycarbonate (PC), and the type is not particularly limited.

A grid-like black pattern called a black matrix can be placed between the color pixels of a color filter to improve contrast. Chrome can be used as a material for the black matrix. In this case, a method of depositing chromium on the entire glass substrate and forming a pattern by etching can be used. However, considering the high cost of the process, the high reflectivity of chrome, and environmental pollution caused by chrome waste liquid, a resin black matrix using a pigment dispersion method that allows microprocessing can be used.

The black matrix according to an exemplary embodiment of the present specification may use black pigment or black dye as a colorant. For example, carbon black can be used alone or a mixture of carbon black and a coloring pigment can be used. In this case, since a coloring pigment with poor light blocking properties is mixed, the strength of the film or adhesion to the substrate decreases even if the amount of coloring material is relatively increased. There is an advantage to not doing this.

The display device includes a plasma display panel (PDP), a light emitting diode (LED), an organic light emitting diode (OLED), a liquid crystal display (LCD), and a thin film transistor. It may be either a liquid crystal display (Thin Film Transistor-Liquid Crystal Display, LCD-TFT) or a cathode ray tube (CRT).

However, the embodiments according to the present specification may be modified into various other forms, and the scope of the present specification is not to be construed as being limited to the embodiments described below. The embodiments of this specification are provided to more completely explain the present specification to those with average knowledge in the art.
