Abstract
(EN) A liquid crystal display panel, comprising: a color filter substrate (10) and an array substrate (20) that are oppositely arranged, and a liquid crystal layer (30) therebetween. The array substrate (20) comprises a base substrate (201); a thin film transistor, which is arranged on the base substrate (201), and comprises a source electrode (2023) and a drain electrode (2024), wherein the drain electrode (2024) comprises an extension portion (2024a); a pixel electrode (203), which is arranged at the extension portion (2024a) of the drain electrode (2024) and is electrically connected to the drain electrode (2024); and a distributed Bragg reflection film (204), which is arranged on the pixel electrode (203). In this way, the present invention effectively improves the reflectivity to light of a total reflection liquid crystal display panel.
(FR) L'invention concerne un écran d’affichage à cristaux liquides comprenant : un substrat de filtre de couleur (10) et un substrat de réseau (20) qui sont disposés à l'opposé l'un de l'autre, ainsi qu'une couche de cristaux liquides entre eux. Le substrat de réseau (20) comprend un substrat de base (201) ; un transistor en couches minces, qui est disposé sur le substrat de base (201), et comprend une électrode de source (2023) et une électrode de drain (2024), l'électrode de drain (2024) comprenant une partie d'extension (2024a) ; une électrode de pixel (203) qui est disposée au niveau de la partie d'extension (2024a) de l'électrode de drain (2024) et est électriquement connectée à l'électrode de drain (2024) ; et un film de réflexion de Bragg distribué (204) qui est disposé sur l'électrode de pixel (203). De cette manière, la présente invention améliore efficacement la réflectivité de la lumière d'un écran d'affichage à cristaux liquides à réflexion totale.
(ZH) 一种液晶显示面板，包括相对设置的彩膜基板（10）和阵列基板（20），以及位于彩膜基板（10）与阵列基板（20）之间的液晶层（30），阵列基板（20）包括衬底基板（201）；薄膜晶体管，设置于衬底基板（201）上，薄膜晶体管包括源极（2023）和漏极（2024），漏极（2024）包括延伸部（2024a）；像素电极（203），设置于漏极（2024）的延伸部（2024a）上，并与漏极（2024）电连接；分布式布拉格反射膜（204）设置于像素电极（203）上，从而有效地提高全反射液晶显示面板对光的反射率。
