ABSTRACT:
In a display device used in an electronic watch or the like, information such as numeric characters or the like and a background are bright and easily displayed. In addition, various information is provided to a viewer, and attracting the viewer's interest is facilitated. The display device includes components of a polarizer, a liquid crystal panel and a polarization separation film. The polarization separation film has a function of transmitting linearly polarized light in one direction and of reflecting other linearly polarized light. A pattern such as a logo, a mark, a character or the like is formed by printing on a light-reflecting layer provided at the back of the polarization separation film. Information such as numeric characters or the like is not displayed as a background of a single color with no pattern, but after rendering a pattern such as a character or the like a background, both information such as numeric characters or the like and the background can be displayed simultaneously.
