Abstract
A display device comprising a display cell consisting of a substrate which is formed by two oppositely located plates whose facing sides are provided with electrode layers to which an orientation layer is applied and a sealing material which is provided between the end portions of the plates, a liquid crystalline material being filled into the space between the plates and the sealing material. In said display device, the liquid crystalline material is locally formed into a polymer network in accordance with a desired pattern. By virtue thereof, the desired pattern of picture elements can be designed with a substantial degree of freedom because it is possible to locally raise the switching threshold of the liquid crystalline material if image formation is not desired at locations where electrodes or conductor patterns cross each other.
