The present invention relates to a colored photosensitive resin composition, a color filter including a black matrix and/or a column spacer manufactured thereby, and an image display device includingthe color filter. According to the present invention, the viscosity of each solvent is equal to or less than 2.0 mPa*s at 20 DEG C and the vapor pressure of each solvent is equal to or less than 3.0 mmHg at 20 DEG C, and an entire solvent satisfies formula 1 (shown in the description), wherein Ai is the viscosity (mPa*s) of each solvent at 20 DEG C, Bi is the vapor pressure (mmHg) of each solventat 20 DEG C, and Mi is a weight ratio of each solvent in the entire solvent. According to the present invention, the colored photosensitive resin composition has excellent levelling properties, thereby being able to form a desired step and effectively suppressing surface defect or surface roughness of a formed black matrix, column spacer, or black matrix-integrated column spacer.
