Abstract
According to one embodiment of the present invention, provided are a dye, a photosensitive resin composition to which the dye is applied, and a display device to which the photosensitive resin composition is applied. The dye includes: a chromophore containing five or more acrylate groups; and a protective group protecting the chromophore, and therefore has excellent light resistance, and thus is not deformed by external sunlight, and also has excellent chemical resistance and reflectance characteristics, and thus is not changed in color by other solvents during a process, even when molded at a low temperature.
