ABSTRACT:
A liquid crystal display element and a process for producing the same is disclosed. The liquid crystal display is composed of liquid crystals filled in a matrix comprising at least two high polymers having neither mutual compatibility nor substantial compatibility with the liquid crystals, said matrix being sandwiched between two transparent electrode bases. The display element is produced by applying a solution of the liquid crystals and the aforesaid high polymers in a common solvent onto a transparent electrode base, drying the solution to cause phase separation, and laminating another transparent electrode base on the dry film. The display element provides a wide display area with bright contrast and achieves orientation of liquid crystals with a low applied voltage.
