Abstract
(EN)
A liquid crystal display panel comprising an array substrate. The array substrate includes a substrate (400), a plurality of common electrode lines provided on the substrate (400), a plurality of scan lines (412) and data lines (443) provided on the substrate and crossed to form a plurality of pixel areas, and a plurality of pixel units. Each pixel unit is provided in the pixel area, and includes a pixel electrode (481) and a switch element electrically connected to the scan line (412), the data line (443) and the pixel electrode (481). The switch element is turned on when a voltage signal on the scan line (412) is applied, and a voltage signal on the data line (443) is transmitted to the pixel electrode (481) so that the pixel electrode (481) has the corresponding electric potential. In the each pixel area, the scan line (412) and the data line (443) are covered with a shielding electrode (461), and the shielding electrode (461) is electrically connected to the pixel electrode (481) or the common electrode line. With the liquid crystal display panel, phenomenon of light leakage can be reduced and high aperture ratio in the pixel unit is achieved.

L'invention concerne un panneau d'affichage à cristaux liquides comprenant un substrat de réseau. Le substrat de réseau comprend un substrat (400), une pluralité de lignes d'électrode communes agencées sur le substrat (400), une pluralité de lignes de balayage (412) et de lignes de données (443) agencées sur le substrat et croisées pour former une pluralité de zones de pixel, et une pluralité d'unités de pixel. Chaque unité de pixel est agencée dans la zone de pixel, et comprend une électrode de pixel (481) et un élément de commutation électriquement connecté à la ligne de balayage (412), la ligne de données (443) et l'électrode de pixel (481). L'élément de commutation est activé lorsqu'un signal de tension sur la ligne de balayage (412) est appliqué, et un signal de tension sur la ligne de données (443) est transmis à l'électrode de pixel (481) de sorte que l'électrode de pixel (481) ait le potentiel électrique correspondant. Dans chaque zone de pixel, la ligne de balayage (412) et la ligne de données (443) sont couvertes par une électrode de protection (461), et l'électrode de protection (461) est électriquement connectée à l'électrode de pixel (481) ou la ligne d'électrode commune. Avec le panneau d'affichage à cristaux liquides, le phénomène de fuite de lumière peut être réduit et un rapport d'ouverture élevé dans l'unité de pixel est obtenu.
