Abstract
A reflective-type multi-color display device is capable of obtaining a vivid and bright multi-color display with less display layers, and therefore, with a state where a parallax is decreased and a cost of the device can be reduced. Specifically, the display device of the present invention includes a cell having a display layer comprising a right-handed cholesteric liquid crystal which selects and reflects blue, a cell having a display layer comprising a left-handed cholesteric liquid crystal which selects and reflects green, a cell having a display layer comprising a right-handed cholesteric liquid crystal which selects and reflects yellow and a cell having a display layer comprising a left-handed cholesteric liquid crystal which selects and reflects red, these layers being laminated in this order from the observation side. A color filter which transmits red and absorbs the other color light is provided between the cell and the cell . A black light-absorbing layer is formed at the back side of the cell
