A method of filling a multilayered cell with media. In the method, a multilayered cell having at least two layers, i.e., a first and second layer, is filled with media. The method comprises forming in the first layer a first medium injection region for filling the first layer with a first medium, forming in the second layer a second medium injection region for filling the second layer with a second medium, the second medium injection region corresponding to a region different from the first medium injection region, superposing the first and second layers, forming within the first medium injection region a first through-hole extending through the multilayered cell in the layer-thickness direction, forming within the second medium injection region a second through-hole extending through the multilayered cell in the layer-thickness direction, and injecting the first and second media into the first and second through-holes, respectively, to fill the first and second layers with the first and second media. Thus, a multilayered cell can be easily produced in a shorter time while attaining a reduction in deterioration during production.

Abstract:
A recording device comprises a display, a photoconductor superposed on the display, and a pair of electrodes disposed on both sides of the display and photoconductor. At least one of the electrodes is divided into sub-electrodes. Information can be written into the recording device by means of light while applying a voltage to each sub-electrode. Therefore, information is not written into part of the recording device corresponding to the sub-element to which no voltage is applied even if extraneous light is applied. As a result a sharp image with no noise can be formed. The recording device also comprises a feed member for applying a voltage to a pair of electrodes of such a recording device, a first light source for writing information in the recording device, and a second light source for reset. Consequently, reset and recording can be done in one cycle.
