Abstract
A display panel and a manufacturing method of a display panel are provided. A display panel includes: a base substrate in which a pixel area and a peripheral area adjacent to the pixel area are defined; a light emitting element located on the base substrate to overlap the pixel area, and configured to generate first light; a light control layer on the light emitting element; a color filter layer on the light control layer; and a capping layer contacting at least the light control layer and including silicon oxynitride (SiON), and the capping layer contains about 34 at % to about 41 at % of oxygen, and about 18 at % to about 25 at % of nitrogen. Luminous efficiency of the display panel may be increased while maintaining durability of the display panel.
