Abstract
(EN)
A liquid crystal display panel (200), comprising an antireflection film (21), an upper polarizer (22), an array substrate (23), a liquid crystal layer (24), a color film substrate (25), and a lower polarizer (26) which are successively stacked. A metallic wire (231) is provided on the array substrate (23); and the antireflection film (21) completely covers the metallic wire (231). The antireflection film (21) is provided on the side of the array substrate (23) distal from the color film substrate (25), so that light destructive interference is applied on reflective light formed on the antireflection film (21) and reflective light formed on the upper polarizer (22), and the reflective light on the liquid crystal display panel (200) is reduced, so that the contrast ratio of the liquid crystal display panel (200) is improved, and the display quality of images can be improved. Therefore, the bezel of a liquid crystal display (500) can be further narrowed, and the contrast ratio is high.

La présente invention concerne un panneau d'affichage à cristaux liquides (200), comprenant un film antireflet (21), un polariseur supérieur (22), un substrat de réseau (23), une couche de cristaux liquides (24), un substrat de film coloré (25) et un polariseur inférieur (26) qui sont successivement empilés. Un fil métallique (231) est disposé sur le substrat de réseau (23) ; et le film antireflet (21) recouvre complètement le fil métallique (231). Le film antireflet (21) est disposé sur le côté du substrat de réseau (23) de façon distale par rapport au substrat de film coloré (25) de telle sorte qu'une interférence destructrice de lumière soit appliquée sur une lumière réfléchissante formée sur le film antireflet (21) et sur une lumière réfléchissante formée sur le polariseur supérieur (22) et la lumière réfléchissante sur le panneau d'affichage à cristaux liquides (200) est réduite de telle sorte que le rapport de contraste du panneau d'affichage à cristaux liquides (200) soit amélioré et que la qualité d'affichage d'images puisse être améliorée. Par conséquent, l'encadrement d'un dispositif d'affichage à cristaux liquides (500) peut être davantage rétréci et le rapport de contraste est élevé.

一种液晶显示面板(200),其中,包括依次层叠设置的减反射膜(21)、上偏光片(22)、阵列基板(23)、液晶层(24)、彩膜基板(25)和下偏光片(26),阵列基板(23)上设置有金属走线(231),减反射膜(21)完全遮盖金属走线(231)。阵列基板(23)远离彩膜基板(25)的一侧设置有减反射膜(21),从而在减反射膜(21)上形成的反射光与上偏光片(22)上形成的反射光经过光线的干涉相消作用,减小液晶显示面板(200)上的反射光线,从而增大液晶显示面板(200)的对比度,提升画面的显示质量。从而,液晶显示器(500)的边框可以进一步做窄,且具有较高的对比度。
