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.

Abstract: A liquid crystal display includes first and second substrates, first and second alignment layers, and a liquid crystal layer between the alignment layers and including liquid crystal molecules. The liquid crystal molecules on a surface of the first alignment layer have a first pretilt angle in a direction which is vertical with respect to a horizontal plane surface parallel to the first substrate, and a first alignment angle in a direction which is horizontal with respect to a horizontal line parallel to the horizontal plane surface. The liquid crystal molecules on a surface of the second alignment layer have a second pretilt angle in the direction which is vertical with respect to the horizontal plane surface and different from the first pretilt angle, and a second alignment angle in the direction which is horizontal with respect to the horizontal line and different from the first alignment angle.
