An optical stack includes a reflective polarizer including a plurality of interference layers and an absorbing polarizer disposed on the reflective polarizer. The plurality of interference layers transmits at least about 85% of an incident light having a first polarization state, reflects at least about 80% of the incident light having a second polarization state, and transmits less than about 0.1% of the incident light having the second polarization state. The absorbing polarizer has a first transmittance for the first polarization state and a second transmittance for the second polarization state. An average of the first and second transmittances is greater than about 0.46. The second transmittance has a first standard deviation. The optical stack has a transmittance for the second polarization state having a second standard deviation which is less than the first standard deviation by at least about 10%. A display includes the optical stack.

Optical stack and display

An optical stack includes a liquid crystal panel with a color filter array. The liquid crystal panel has a filter side closest to the color filter array and a non-filter side opposite the filter side. An absorbing polarizer is laminated directly to the filter side of the liquid crystal panel, and a reflective polarizer laminated directly to the absorbing polarizer.
