The EW method, one of the micro-fluidic phenomena, has been investigated by applying to a shutter of the pixelwith electronic papers. There are many technical papers for EW display devices, however, few papers about a displaymemory function are found. The display memory is important function for the electronic paper for the low power consumption. In this paper, a novel pixel structure was proposed for the display device by using the fundamental technique ofEW, and the electrodes structure and the liquid material were investigated. A chiral nematic LC material doped withthe dichroic dye was used as the liquid material instead of the conventional dyed oil. As a result, the memory functioncould be induced by the thixotropic effect of LC material and the transparence mode was obtained by applying the voltageto the LC.
