Abstract
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.
