A liquid crystal display screen having a liquid crystal layer disposed between a pair of carrier plates to form a liquid crystal cell characterized in a plurality of electrode layers disposed between the carrier plates with adjacent electrode layers being separated by an insulating layer and selected electrode layers being in the shape of characters or digits and being energized to form displays of different characters or digits. In one embodiment, a digit electrode layer is applied on opposite faces of the liquid crystal layer and a continuous electrode is separated by an insulating layer from each of the additional electrode layers. In a second embodiment, the liquid crystal layer is disposed between a continuous electrode layer and more than two digit electrode layers with the outermost digit electrode layer being continuous whereas the inner digit electrodes have interrupted conducting surfaces. In the third embodiment, a color filter such as a three-color triplet having the colors arranged in strips is disposed between the carrier plates, the continuous electrode is formed by three electrode layers separated by insulating layers with each layer having strips of electrodes overlying the strips of a specific color so by selecting the energizing of various electrodes, a character of one color can be produced.
