Abstract:
1. A structure for reducing internal reflections in an optical system, comprising a stack of layers including a first layer having a first refractive index, a second layer having a second refractive index, a third layer having a third refractive index, a fourth layer having a fourth refractive index, and a fifth layer having a fifth refractive index, wherein the second layer is arranged between the first layer and the third layer, and the fourth layer is arranged between the third layer and fifth layer, and wherein the third refractive index is numerically greater than both the second and fourth refractive indexes, the second refractive index is numerically greater than the first refractive index, and the fourth refractive index is numerically greater than the fifth refractive index, wherein the first layer comprises a color filter, the second layer comprises a polyimide, the third layer comprises an indium-tin-oxide electrode, the fourth layer comprises a polyimide and the fifth layer comprises a liquid crystal layer.
