Abstract

The colored photosensitive resin composition of the present invention maintains excellent resolution, visibility, and the like while it has excellent reflectance RSCI measured by the SCI (specular component included) method, reflectance RSCE measured by the SCE (specular component excluded) method, and the ratio between them (RSCE/RSCI), and has a uniform film thickness in an appropriate range. Thus, it can be formed into a multilayer cured film that simultaneously satisfies such physical properties as a high reflectance and a high light-shielding property. In addition, when a cured film is formed from the composition, it is possible to form a pattern on a multilayer film in a single development process. Thus, it can be advantageously used for a quantum dot display device.
