First Claim
1. A display device comprising:
- a first absorptive polarizer;
a first liquid crystal arrayed adjacent to the first absorptive polarizer;
a second absorptive polarizer arrayed adjacent to the first liquid crystal, wherein the second absorptive polarizer is cross polarized with the first absorptive polarizer;
a reflective polarizer arrayed adjacent to the second absorptive polarizer;
a second liquid crystal arrayed adjacent to the reflective polarizer; and
a third absorptive polarizer arrayed adjacent to the second liquid crystal, wherein the third absorptive polarizer is cross polarized with respect to the reflective polarizer.
