Abstract
A display panel includes: a light emitting device to generate light; a plurality of color conversion patterns including: a first color conversion pattern including first scattering particles dispersed in the first color conversion pattern and configured to scatter the light of the light emitting device; and a second color conversion pattern including second scattering particles dispersed in the second color conversion pattern and configured to scatter the light of the light emitting device; a plurality of color filters including: a first color filter overlapping the first color conversion pattern; and a second color filter overlapping the second color conversion pattern; and a single, low index of refraction layer substantially continuously extending in the surface direction to overlap the first and the second color conversion patterns. The single, low index of refraction layer has a refractive index lower than refractive indexes of the first and second color conversion patterns.
