One polarizer type reflective LCDs require a quarter wave plate. However, conventional quarter wave plate using uniaxial retardation films have poor viewing angle and high wavelength dependences. In this paper, we designed a quarter wave plate with wide viewing angle and wide wavelength range by using three biaxial retardation films. In addition, we realized a high quality reflective LCD with wide viewing angle range and high contrast ratio by applying this quarter wave plate and wide‐view polarizer to the R‐OCB cell.
