Abstract
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.
