Description

Photosensitive resin composition and color filter including the same

This specification relates to a photosensitive resin composition and a color filter including the same.

In recent years, the color filter is required to be characterized by high brightness and high contrast ratio. In addition, one of the main purposes of the development of display elements is to differentiate the performance of display elements due to the improvement in color purity and to improve the productivity in manufacturing steps.

Previously, the type of pigment used as a coloring agent for a color filter existed in the color photoresist in a particle dispersed state, and therefore, it was difficult to adjust the brightness and contrast ratio by adjusting the size and distribution of the pigment particles. In the case of pigment particles, they aggregate in a color filter, have poor solubility and dispersibility, and cause multiple scattering of light due to aggregation of large particles. It has been pointed out that the scattering of the polarized light is the main reason for the decrease in the contrast ratio. Efforts are being made to improve brightness and contrast ratios by ultra-micronization of pigments and stabilization of dispersion. However, there is a limited degree of freedom in the choice of colorants to achieve color coordinates for display devices with high color purity. . In addition, the color purity, brightness, and contrast ratio of color filters have been increased by using a pigment dispersion method using developed coloring materials, especially pigments. Therefore, it is required to develop a coloring agent or a photosensitive resin composition containing the same for improving color reproducibility, brightness, and contrast by improving color purity.
