摘要：
Although dyes have superior spectral characteristics, they are not widely used as coloring materials for liquid crystal display color filters owing to their low thermal stability. Four perylene and four phthalocyanine dyes of high thermal stability were synthesized and then used to fabricate color filters. The spectral and thermal stabilities of the color filters were investigated by comparing them with pigment-dispersed color filters. The transmittance and color properties of the prepared color filters were higher and the thermal stability was similar to those of the pigment-dispersed color filters. The results showed that the prepared dyes could be successfully applied in ink-jet printed liquid crystal display color filters. (C) 2008 Elsevier Ltd. All rights reserved.
