Patent ID: 7256551

Claim:
An image displaying method, comprising the steps of: i) overlaying; a) a first electrode layer, which is capable of transmitting visible light, b) a displaying layer, whose optical characteristics alter in accordance with an electric field, c) an optical switching layer, which is capable of exhibiting electrical conductivity when being exposed to an electromagnetic wave, and d) a second electrode layer, which is provided with a plurality of linear electrodes arrayed in parallel with one another, the linear electrodes being capable of transmitting the electromagnetic wave, in this order, ii) applying a voltage to each of the linear electrodes and in accordance with image information, and iii) performing scanning with the electromagnetic wave in two-dimensional directions and from the side of the second electrode layer, an electric field being formed between the first electrode layer and the optical switching layer by electric charges, which are caused to occur in the optical switching layer by the scanning with the electromagnetic wave, the optical characteristics of the displaying layer altering in accordance with the electric field, whereby the image information is displayed.
