摘要 PCT No. PCT/JP98/02001 Sec. 371 Date Aug. 24, 1998 Sec. 102(e) Date Aug. 24, 1998 PCT Filed May 1, 1998 PCT Pub. No. WO98/50819 PCT Pub. Date Nov. 12, 1998A display device including a color polarizer (11), a liquid-crystal panel (8) and a polarizing splitter (32). The color polarizer (11) transmits all wavelengths (arrows Q and S) or a specific wavelength of a light ray (arrows P and R) depending on the direction of the polarization axis of the linearly polarized light ray. The polarizing splitter (32) transmits a light ray linearly polarized in one direction (arrows Q and R) and reflects the remainder of the linearly polarized light rays. A reflective display presents two display states depending on light paths P and S, and a transmissive display presents two display states depending on light paths T and U, and in either case, a multi-color display is obtained. Since the light reflection from the polarizing splitter is used during a reflective displaying, a bright display results.
