Title: DISPLAY ELEMENT AND ELECTRONIC CLOCK
Abstract:
A display element provided with a color polarizing plate (11), a liquid crystal panel (8), and a polarized light separator (32), wherein the polarizing plate (11) transmits either a light of all wavelengths (arrows Q and S) or only a light having a specific wavelength (arrows P and R) in accordance with the direction of the axis of polarization of linearly polarized light, and the polarized light separator (32) transmits a linearly polarized light in a certain direction (arrows Q and R) and reflect the other polarized light (arrows P and S). A reflection display element exhibits two displaying states depending upon optical paths P and S, while a transmission display element exhibits two displaying states depending upon optical paths T and U, thus providing multicolored displays in either case. In the case of the reflection display element, a bright display can be realized, because the reflection of light in the separator (32) is utilized.
