Abstract
A liquid crystal image displaying/reading apparatus includes a first transparent substrate; a second transparent substrate placed in parallel with the first transparent substrate with a fixed space therebetween; a set of display electrodes formed on the first transparent substrate and the second transparent substrate so that a plurality of display pixels arranged in a matrix with a prescribed gap therebetween are formed at the first transparent substrate; a plurality of light receiving elements formed between the first transparent substrate and the second transparent substrate at the position facing the gap for receiving light to convert the light into current; a reading device formed at the position facing the gap with the light receiving elements interposed for reading a signal received by the light receiving elements; and liquid crystal loaded between the first transparent substrate and the second transparent substrate, wherein the reading device includes a first transparent reading electrode formed on the side of the first transparent substrate with respect to the light receiving elements, and a second reading electrode formed on the side of the second transparent substrate with respect to the light receiving elements.
