Abstract
(EN)
A liquid crystal panel, comprising a first substrate (1), a second substrate (2) provided opposite the first substrate (1), a liquid crystal layer (5) provided between the first substrate (1) and the second substrate (2), and a sealing plastic frame (4) provided between the first substrate (1) and the second substrate (2) and surrounding the liquid crystal layer (5). The liquid crystal layer (5) comprises an effective liquid crystal area (31) and an edge liquid crystal area (32) surrounding the effective liquid crystal area (31). The first substrate (1) comprises a first base (11), a black matrix (12) provided on the side of the first base (11) facing the second substrate (2), and a common electrode (13) provided on the black matrix (12) and on the first base (11). The second substrate (2) comprises a second base (21) and a shading electrode (22) provided on the side of the second base (21) facing the first substrate (1). With multiple transparent slits (121) arranged at an interval provided on the black matrix (12) directly opposite the edge liquid crystal area (32), the shading electrode (22) provided corresponding to the edge liquid crystal area (32) and covering the entire edge liquid crystal area (32), and the shading electrode (22) electrically connected to the common electrode (13), the full reaction of a reactive monomer in the liquid crystal layer (5) is ensured and poor peripheral display is prevented. Also provided is a pretilt angle forming method.

La présente invention concerne un écran à cristaux liquides comprenant un premier substrat (1) ; un second substrat (2) situé à l'opposé du premier (1) ; une couche de cristaux liquides (5) intercalée entre le premier et le second substrat (1, 2) ; et un cadre d'étanchéité en plastique (4) intercalé entre le premier et le second substrat (1, 2) entourant la couche de cristaux liquides (5). La couche de cristaux liquides (5) comprend une zone de cristaux liquides efficace (31) et une zone de cristaux liquides de bord (32) entourant la zone de cristaux liquides efficace (31). Le premier substrat (1) comprend une première base (11), une matrice noire (12) disposée sur le côté de la première base (11) faisant face au second substrat (2) et une électrode commune (13) disposée sur la matrice noire (12) et sur la première base (11). Le second substrat (2) comprend une seconde base (21) et une électrode d'ombrage (22) disposée sur le côté de la seconde base (21) faisant face au premier substrat (1). Avec de multiples fentes transparentes (121) agencées à un intervalle prévu sur la matrice noire (12) directement à l'opposé de la zone de cristaux liquides de bord (32), l'électrode d'ombrage (22) disposée correspondant à la zone de cristaux liquides de bord (32) et recouvrant la totalité de la zone de cristaux liquides de bord (32) et l'électrode d'ombrage (22) connectée électriquement à l'électrode commune (13), la réaction complète d'un monomère réactif dans la couche de cristaux liquides (5) est assurée et un affichage périphérique médiocre est empêché. L'invention concerne aussi un procédé de formation d'un angle préincliné.
