There is provided a novel dichroic dye having liquid crystal properties, dichroic properties and polymerizable reactivity, the dichroic dye being used to form a color filter layer having excellent physical properties such as dichroic ratio, heat resistance, durability, high contrast ratio and polarizing properties, a composition comprising the same for color filter, a color filter array plate (an upper plate) prepared therefrom, and a liquid crystal display comprising the color filter array plate. The dichroic dye has a structure of R1-L1-M-L2-D (wherein, D is a dichroic structure, M is a structure with liquid crystal properties, R1 is a reactive end functional group, and L and L1 are linking structures that link R1, M, and D), and the composition for forming a color filter layer includes the dichroic dye. Also, the color filter array plate, which comprises color filter layer formed of the composition of this invention and the liquid crystal display, which comprise the color filter array plate but does not requires an upper alignment film and/or a polarization plate are provided. The color filter array plate and the liquid crystal display comprising the same have excellent physical properties such as durability, polarizing degree, resolution and contrast ratio.
