Abstract
A display apparatus and a filter for improving color purity (color saturation filter) are disclosed. In one aspect, the display apparatus includes a substrate, a display device formed on the substrate and having a plurality of pixel areas that emit different colors of light, and a color saturation filter on the display device. The color saturation filter is formed with a substantially uniform thickness over the plurality of pixel areas and has a transmissivity such that a full width at half maximum at the central wavelength of blue light emitted from one of the pixel areas is about 100 nm or less.
