Abstract
A reflective color filter includes: a first domain reflecting visible red colored light at substantially normal angles of incidence; a second domain reflecting invisible infrared colored light at substantially normal angles of incidence and reflecting red colored light at an oblique angle of incidence, greater than zero degrees; a third domain reflecting green red colored light at substantially normal angles of incidence; and a fourth domain reflecting blue colored light at substantially normal angles of incidence. In one configuration, the second domain overlies or underlies the first domain, but not the third or fourth domains. The reflective color filter can be used in a color liquid crystal display device.
