Organic dyes with low dielectric constant have recently been suggested as a replacement for Cr/CrOx or carbon black in developing black matrices with low dielectric constants for liquid crystal displays. However, due to a spectral property of the dyes which generally shows narrow absorption range, black matrix based on dyes needs to be fabricated by material mixture method. In this study two dyes which can cover the whole visible region by the mixture method were synthesized based on perylene dyes and dye type, carbon black type and hybrid type black matrices were fabricated. The characterization of the dyes were investigated by UV-Visible spectrometer and thermogravimetric analysis. The thermal, optical and dielectric properties of the black matrices were examined by color spectroscopy, optical density measurement and impedance analysis. |
