Abstract
Two perylene dyes having different absorption ranges were synthesized for an application in liquid crystal display black matrix. Hybrid-type and dye only-type black matrices were fabricated using the synthesized dyes and carbon black. Among the fabricated films, the hybrid-type film, which contained the same weight ratio of the dyes and carbon black showed high thermal and optical properties and had a low dielectric constant. Additionally, the surface of the film had low root-mean-squared roughness (Rq) value and was sufficiently flat in comparison to the film containing different chromophores that showed self-aggregation of the dyes described in previous research.
