Abstract: A method of fabricating a reactive mesogen (RM) guest-host polarizer is disclosed. The method includes forming an RM guest-host polarizer material on a substrate that promotes a substantially uniform planar alignment configuration of the RM guest-host molecules, forming a temporary layer on the RM guest-host polarizer material to align RM guest-host molecules of the RM guest-host polarizer material in the substantially uniform planar alignment configuration, performing polymerization of the RM guest-host polarizer material, and removing the temporary layer from the RM guest-host polarizer. The temporary layer includes at least one of a temporary fluid layer, a temporary particulate layer, a temporary gaseous layer, a temporary vacuum layer, and a temporary alignment substrate layer.

Abstract: A liquid crystal display (LCD) apparatus that has increased contrast in displayed images, from the viewing side includes; a first external linear polarizer layer having a transmission axis aligned along in a first direction, a color filter substrate layer. A patterned color filter layer including individual color filters, a guest-host in-cell polarizer alignment layer an in-cell guest-host polarizer layer having a transmission axis aligned along the first direction, a first liquid crystal (LC) alignment layer, an LC layer, a second LC alignment layer, a first electrode layer, a thin film transistor (TFT) substrate layer, a second external polarizer layer having a transmission axis aligned along a second direction perpendicular to the first direction, and a backlight unit configured for illuminating the LCD apparatus.
