摘要： A display device includes a substrate, a light emitting diode disposed on the substrate and that emits light that has a preset color, a capping layer disposed on the light emitting diode and that has a thickness of about 540 angstroms to about 640 angstroms, and a thin film encapsulation layer disposed on the capping layer. As the capping layer has a predetermined thickness, a reflectance of external light is reduced, a color bleeding phenomenon is reduced, and the luminous efficiency of the light emitting diode is increased.

摘要： By controlling the optical thickness of the upper stacked structure disposed on the display panel, it is possible to periodically control the tristimulus value of Xr and the tristimulus value of Yg emitted from the electronic device. The optical thickness is determined by the thickness and refractive index of the upper stacked structure. This control may reduce the tristimulus value of Xr periodically or increase the tristimulus value of Yg periodically. The tristimulus value of Xr may be periodically decreased and the tristimulus value of Yg may be periodically increased at the same time.
