    • 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 51 having a display layer 31 comprising a right-handed cholesteric liquid crystal which selects and reflects blue, a cell 53 having a display layer 33 comprising a left-handed cholesteric liquid crystal which selects and reflects green, a cell 57 having a display layer 37 comprising a right-handed cholesteric liquid crystal which selects and reflects yellow and a cell 55 having a display layer 35 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 43 which transmits red and absorbs the other color light is provided between the cell 57 and the cell 55. A black light-absorbing layer 41 is formed at the back side of the cell 55.

    • A cholesteric liquid crystal display capable of rewriting at a high speed is provided, which includes a cholesteric liquid crystal display element forming pixels at intersection portions of scan-electrodes of a scan-electrode group and data-electrodes of a data-electrode group, in which L-lines (L: integer lager than 2) of the scan-electrodes each of the scan-electrode group form a block. The drive circuit sequentially selects one block during one selection time, simultaneously applies coded drive voltages each corresponding to the L-lines of the scan-electrodes in the selected block, and applies coded data-voltages each corresponding to data-electrodes of the data-electrode group synchronously with the drive voltages.
