ABSTRACT:
The present invention is directed to a display device which comprises two layers of insulating substrate, at least the substrate on the viewing side is transparent, an array of display cells sandwiched between the two layers of substrate, a writing means, and optionally an erasing means to magnetically or electrically erase the image. The display cells are filled with a dispersion of magnetic particles which may be charged or non-charged. The display of the invention eliminates the use of the transparent conductor film, such as ITO, on the viewing side. Therefore, the displays of this invention are more cost effective, more flexible and durable and capable of higher image contrast ratio and higher reflectance in the Dmin area.
