Abstract
A display device including a light source and a pixelized color filter element is provided. The pixelized color filter element includes a plurality of first pixelized filters, a plurality of second pixelized filters and a plurality of third pixelized filters. The pixelized color filter element has a total reflectance higher than 5% in a wavelength range of 400 to 700 nm. At least one of the first pixelized filters, second pixelized filters and third pixelized filters includes a first layer and a second layer. The first material layer has a transmittance higher than 50% in a wavelength range of 400 to 700 nm. The second material layer has a transmittance higher than 50% in a wavelength range of 400 to 700 nm.
