Problems solved by technology

Efforts have been made to improve the brightness and contrast ratio by ultrafine particle size and dispersion stabilization of pigments, but the degree of freedom is limited in the selection of colorants for the color coordinates of display devices to achieve high color purity
In addition, the pigment dispersion method using already developed color materials, especially pigments, has reached its limit in the improvement of color purity, brightness and contrast ratio of color filters using the pigments

[0220] Production of the substrate

[0221] The produced compound was spin-coated on SiNx-deposited glass (5 cm×5 cm), and prebaked at 110° C. for 70 seconds to form a film. The distance between the substrate on which the film was formed and the photomask (photo mask) was set to 300 μm, and the entire surface of the substrate was irradiated with 30 mJ / cm using an exposure device. 2 exposure.

[0222] Thereafter, the exposed substrate was developed with a developer (KOH, 0.04%) for 55 seconds, and post baked at 230° C. for 20 minutes to prepare a substrate.

A color filter contains the photosensitive resin composition.SELECTED DRAWING: Figure 1

Description

technical field [0001] This specification relates to a photosensitive resin composition and a color filter containing the photosensitive resin composition. Background technique [0002] In recent years, performances characterized by high luminance and high contrast ratio have been required for color filters. In addition, one of the main purposes of the development of display elements is to improve the performance differentiation of display elements and the improvement of productivity in the manufacturing process by improving the color purity. [0003] Pigments conventionally used as colorants for color filters exist in a color photoresist in a particle-dispersed state, so it is difficult to adjust the brightness and contrast ratio by adjusting the size and distribution of pigment particles. In the case of pigment particles, they are aggregated in the color filter, resulting in poor solubility and dispersibility, and multiple scattering (multiplescattering) of light by aggre...
