Abstract: An image displaying apparatus, a method for displaying an image and an image displaying medium can provide an image of a large viewing angle and high stability of the particles upon repeated use. On electronic paper containing a display substrate formed of a hole transporting film, a non-display substrate formed of a film having a two-layer structure containing a charge transporting film having formed thereon an electrode layer having a thickness of about 50 &mgr;m, and conductive black particles and insulating white particles contained therebetween, an electric field is generated at a position corresponding to image data by a recording head, so as to move the black particles attached to the entire surface of the display substrate toward the non-display substrate, whereby an image of contrast of black and white is formed on the display substrate.

Abstract: A method of forming a reversible color image of forming a multi color image to a reversible heat sensitive color recording medium in which recording layers each containing independently a plurality kinds of reversible heat color forming compositions having tone of formed color and color erasure starting temperature different from each other are formed on a support, the method comprising forming colors of all the compositions in the initial state and heating the color formed compositions not imagewise at different temperatures thereby erasing the color of the composition (recording layer 2). The color image can be formed simply and rapidly at a high energy efficiency.

Abstract: A method and apparatus in which the liquid crystal material having cross-over frequency is used for displaying an image, the liquid crystal material is dispersed in the transparent polymer in a phase-separated state, a first voltage signal having a first frequency lower than the cross-over frequency is applied to the liquid crystal material to orient reversibly the liquid crystal material to a first direction to display temporary information, then a second voltage signal having a magnitude higher than the first voltage is selectively applied to orient permanently the liquid crystal material to the first direction to display permanent information and a third voltage signal having a second frequency higher than the cross-over frequency is selectively applied to orient the liquid crystal material perpendicularly to the first direction, to erase the permanent information.

Abstract: An optically addressing liquid crystal displaying and recording device is capable of obtaining good images free of non-uniformity of density without impairing the characteristics of a light modulating layer. The device includes a light modulating layer 1 including liquid crystals, a photoconductive layer 2 laminated on one side of the light modulating layer 1 and a voltage controlling device 3 for controlling the polarity of the voltage applied to the light modulating layer 1 and the photoconductive layer 2. The device further includes an exposing device 4 for repeatedly scanning a beam on the photoconductive layer 2, a detecting device 5 for detecting scanning of a beam and a controlling device 3 for controlling a timing when the voltage is applied in accordance with a detecting signal outputted by the detecting device 5.

Abstract: Light-controlling layer which contains at least a liquid crystal as a component is combined with photoconductive layer that is provided on the side of the layer closer to exposing unit and the impedance of which varies in accordance with the intensity of input light. Exposing unit exposes the photoconductive layer to write image into the light-controlling layer. Gradation control unit modulates the output light of the exposing unit on the basis of a signal indicative of the multi-level density of the image to be written, thereby controlling the light transmittance of the light-controlling layer.
