Description

Compounds, colorant compositions, photoresists, color filters, and and display device

This application claims the benefit of the filing date of Korean Patent Application No. 10-2018-0106491 filed with the Korea Intellectual Property Office on September 6, 2018, the entire contents of which are included in this specification.

This specification is about a compound, a colorant composition, a photoresist, a color filter, and a display device.

Currently, in order to realize a color filter, a pigment dispersion method using a pigment as a colorant is generally applied. However, in the case of a pigment dispersion liquid, the pigment exists in a particle state and not only scatters light, but also rapidly increases the surface area of the pigment due to the miniaturization of the pigment, and the resulting deterioration of the dispersion stability results in the generation of non-uniform pigment particles. Therefore, in order to achieve the high brightness, high contrast, and high resolution recently required, the use of dyes as colorants instead of pigments has recently been studied.

Generally, dyes have the advantage of high transmittance compared to pigments. However, it has the disadvantage of insufficient heat resistance compared with pigments. In addition, compared with existing pigments, organic The solubility of the solvent is good, so it has the disadvantage of insufficient chemical resistance.
