Abstract: The present invention relates to a colored photosensitive resin composition and to a light-shielding black matrix prepared therefrom. The colored photosensitive resin composition of the present invention is capable of providing a cured film that satisfies such characteristics as high light-shielding property and low reflectance at the same time by more effectively reducing the total reflectance, which is a smaller-the-better characteristic that should be satisfied as a light-shielding black matrix, while the optical density, resolution, leveling characteristics, visibility, and the like are maintained to be excellent. Thus, the light-shielding black matrix prepared from the composition can be advantageously used in liquid crystal displays and quantum dot displays.
