发明名称 Electronic timepiece
摘要 An electronic timepiece provides a bright and easy-to-read display, and a greater variety of display forms of numerical information, or the like, and a greater variety of background colors. The electronic timepiece may include a polarizer, a liquid crystal element, and a polarization separating film. The polarization separating film transmits linearly polarized light polarized in a certain direction and reflects all other linearly polarized light. The internal structure of the polarization separating film may be divided, in a plane, into polarization separating portions which reflect light of different wavelengths. The polarization separating film reflects different colors in correspondence to the polarization separating portions. Using a reflecting-type polarization separating film allows a bright display to be realized, and providing a plurality of polarization separating portions allows a greater variety of display forms to be realized.
