Abstract: A display device includes a first substrate, a pixel structure, a first optical filter, a first-color filter, a second optical filter, a second-color filter, and a second substrate. The pixel structure is disposed between the first substrate and each of the optical filters. The first-color filter is disposed on the first optical filter and has a first refractive index. The second optical filter is spaced from the first optical filter and includes a second-color pigment. The second-color filter is disposed on the second optical filter and has a second refractive index. The second substrate is disposed on the first color filter and the second color filter and has a third refractive index. A difference between the third refractive index and the second refractive index is less than a difference between the third refractive index and the first refractive index.
