A liquid crystal display structure includes a liquid crystal display cell having a front surface and a back surface. One or more intrinsic polarizers lacking protective coatings thereon, such as K-type polarizers and thin KE polarizer sheets, are disposed adjacent to the front and back surfaces of the liquid crystal display cell. Alternatively, thinly cladded or encased iodine polarizers are disposed adjacent to the front and back surfaces of the liquid crystal display cell. The liquid crystal display structure may be used in conjunction with other optical display elements to enhance the brightness and contrast of the liquid crystal display.

L'invention concerne une structure d'affichage à cristaux liquides comprenant une cellule d'affichage à cristaux liquides dotée d'une surface avant et d'une surface arrière. Un ou plusieurs polariseurs intrinsèques manquant de revêtements protecteurs, tels que des polariseurs de type K et des feuille minces de polariseurs KE, sont disposé(s) adjacent(s) aux surfaces avant et arrière de la cellule d'affichage à cristaux liquides. Dans un autre mode de réalisation, les polariseurs à iode finement gainés ou incorporés sont disposés adjacents aux surfaces avant et arrière de la cellule d'affichage à cristaux liquides. On peut utiliser la structure d'affichage à cristaux liquides associée à d'autres éléments d'affichage optiques afin d'améliorer la brillance et le contraste de l'affichage à cristaux liquides.
