Title (EN) LIQUID CRYSTAL DISPLAY
(FR) AFFICHEUR A CRISTAUX LIQUIDES
Abstract:
(EN) A liquid crystal display panel in which a signal electrode provided on a first substrate (1), a counter electrode provided on a second substrate (2), and a liquid crystal layer (18) between the substrates joined with a predetermined space through a sealing part are arranged, and which carries out display by changing the degree of transmission and scattering by means of a voltage applied to a pixel part. A light source part (27) is provided along the periphery of both substrates, the part opposed to the light source part of the sealing part is translucent, and a polarized light separating device (30) is provided between the liquid crystal panel and the light source part (27).
(FR) L'invention concerne un panneau d'affichage à cristaux liquides dans lequel sont arrangés une électrode indicatrice disposée sur un premier substrat (1), une contre-électrode disposée sur un deuxième substrat (2) et une couche de cristaux liquides (18) disposée entre les substrats assemblés, lesquels comportent un espace préétabli à travers une pièce d'étanchéité. L'affichage s'effectue par modification du degré d'émission et de diffusion obtenue par application d'une tension sur une pièce à pixels. Une source lumineuse (27) est disposé le long de la périphérie des deux substrats. La partie opposée à la source lumineuse de la pièce d'étanchéité est translucide, et un dispositif de séparation (30) de lumière polarisée est placé entre le panneau à cristaux liquides et la source lumineuse (27).
