Abstract:
A reflective display apparatus comprising:a polarizing beam splitter (PBS) adapted to transmit a P polarized beam of an incident beam and to reflect an S polarized beam thereof;a compensator which converts the incident beam from the PBS into a polarized beam and then transmits the polarized beam, and converts a beam returning after the polarized beam has been transmitted into a polarized beam and proceeds to the PBS, in which a molecular axis of each pixel is aligned in any one direction among .+-..alpha..degree. directions based on a vertical axis when a driving voltage is applied; anda reflective liquid crystal display device which converts the incident beam after the beam is transmitted through the compensator into a polarized beam and then reflects the polarized beam, and which converts the reflected beam into a polarized beam and proceeds to the compensator, in which a molecular axis of each pixel is aligned in any one direction among .+-..beta..degree. directions based on a horizontal axis when a driving voltage is applied,wherein an angle between the molecular axis of the compensator and that of the reflective liquid crystal display device is formed as 90.degree. in a case where the beam transmits through the compensator and proceeds to the PBS, and transmits through the PBS, thereby enhancing a contrast ratio.
