Abstract: A display panel may include a first display substrate and a second display substrate on the first display substrate. The second display substrate may include a plurality of pixel regions and a peripheral region adjacent to the pixel regions. The second display substrate may include a first color control pattern configured to emit light of a first color, a second color control pattern spaced apart from the first color control pattern in a first direction and configured to emit light of a second color different from the first color, and first and second light-blocking patterns in the peripheral region between the first and second color control patterns. The first and second light-blocking patterns may be spaced apart from each other, in a second direction crossing the first direction, to define a gap region.

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.
