Abstract

A display panel includes a light emitting element that outputs source light and that includes a first electrode, an emissive layer over the first electrode, and a second electrode over the emissive layer and a light control layer over the light emitting element. The light control layer includes at least one light control pattern and a barrier layer that is on one surface of the light control pattern and that contains silicon oxy-nitride (SiON). The barrier layer contains 0.1 atomic % to 18 atomic % nitrogen, 42 atomic % to 70 atomic % oxygen, and 25 atomic % to 45 atomic % silicon. Accordingly, the durability and barrier characteristics of the barrier layer and the light conversion efficiency of the light control pattern may be improved, and thus the reliability and display efficiency of the display panel including the barrier layer and the light control pattern may be enhanced.
