Abstract
An arrangement to produce pictures using light polarized in different directions consists of a picture tube to whose faceplate a polarizer film and a polymer liquid crystal film provided on both sides with transparent conductive layers are joined with a transparent adhesive. By using a polymer liquid crystal film, the arrangement can also be realized on picture tubes having curved faceplates. The polarizer film and the polymer liquid crystal film are joined together preferably by laminating, and the laminate is joined to the faceplate with an adhesive. The polymer liquid crystal film preferably contains a ferroelectric liquid crystal material.
