摘要： This invention provides a storage medium, method of writing images to a storage medium, method of forming a storage medium and a storage medium formed using the method of forming a storage medium. The storage medium provides a display which has memory capability without power, allows images to be updated quickly by external equipment, and is capable of a full-color display. The storage medium includes three display layers having cholesteric liquid crystals which selectively reflect blue, green, and red, respectively, and are different from each other in texture change threshold voltage. The display layers are stacked between substrates and a light absorption layer is provided. An image writing apparatus is formed separately from the storage medium and provides write electrodes sandwiching the storage medium. A write signal is applied between the electrodes with a voltage, wherein the voltage is selected from seven levels of voltage which are produced based on the respective texture change threshold voltages of the cholesteric liquid crystal display layers.
