Abstract
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.
Claims19
An optical stack, comprising:
- a liquid crystal panel including a color filter array, the liquid crystal panel including a filter side closest to the color filter array and a non-filter side opposite the filter side;
- an absorbing polarizer laminated directly to the liquid crystal panel on the filter side thereof;
- and
- a reflective polarizer laminated directly to the absorbing polarizer.

An optical stack, comprising:
- a liquid crystal panel including
- a backlight-side substrate;
- a front-side substrate;
- a liquid crystal layer disposed between the backlight-side substrate and the front-side substrate, a light-scattering intensity (Iback [550]) of the backlight-side substrate being higher than a higher light-scattering intensity (Ifront [550]) of the front-side substrate;
- an absorbing polarizer laminated directly to the backlight-side substrate;
- and
- a reflective polarizer laminated directly to the absorbing polarizer.
