The invention provides a green photosensitive resin composition, a color filter and an image display device. The green photosensitive resin composition comprises a coloring agent, alkali-soluble resin, a photopolymerizable compound, a photopolymerization initiator and a solvent, wherein the colorant comprises a pigment having a transmittance of 80% or more and less than 99% in a wavelength range of 450 nm to 500 nm and a transmittance of 40% or more and less than 99% in a wavelength range of 760 nm to 780 nm; and the alkali-soluble resin includes one or more repeating units selected from the group consisting of repeating units represented by Chemical Formulae 1 to 3. Therefore, the green photosensitive resin composition has excellent transmissivity and excellent contrast to exhibit enhanced color reproducibility and exhibit excellent adhesion or chemical resistance and improved development rate.
