Abstract
A display device and an electronic timepiece displays information, such as numerical information, and the background has a glossy silver metallic tone, to give the display a quality appearance. The display device and the electronic timepiece includes a polarizer, a liquid crystal panel, and a polarization separating film. The polarization separating film transmits linearly polarized light oriented in a certain direction and reflects all other linearly polarized light. The surface of the polarization separating film which opposes the liquid crystal panel, is formed into a smooth surface which specularly reflects light, and a light-scattering layer is not provided therebetween. Light, reflected from the polarization separating film, is used to produce a glossy silver background color or information display with a metallic tone in order to give the display a quality appearance.
