ABSTRACT:
A display device is constituted by disposing a first display layer and a second display layer between a pair of electrode plates including at least one transparent electrode plate. The first display layer contains a low-molecular weight mesomorphic compound dispersed in or impregnating a polymer matrix. The second display layer is formed by disposing a diffraction grating and being filled with the low-molecular weight mesomorphic compound. The display device is incorporated in a display apparatus to effect a good display with a high contrast ratio.
