Disclosed is a light divergence angle limiting apparatus for improving color purity and displaying a high-quality image by blocking unnecessary color rays except for a predetermined color ray. A divergence angle of at least one of a plurality of color rays is limited in consideration of light emission characteristics of a light source so that color rays (for example, B and G rays) different from a predetermined color ray (for example, R ray) do not enter a pixel corresponding to the predetermined color ray by using a light blocking plate provided as a light divergence angle limiting apparatus.
