Abstract:
(EN) A display panel and a manufacturing method therefor, and a display apparatus. The display panel comprises: a first substrate (100) and a reflective second substrate (200) arranged opposite each other; a liquid crystal layer (300) located between the first substrate (100) and the second substrate (200); a first polarizing layer (400) arranged at one side, away from the second substrate (200), of the liquid crystal layer (300); and a second polarizing layer (500) arranged between the liquid crystal layer (300) and the second substrate (200), wherein the second polarizing layer (500) is configured to make transmitted light have a first polarization direction; in the case where no voltage is applied to the liquid crystal layer (300), light transmitted through the liquid crystal layer (300) and the first polarizing layer (400) has a second polarization direction; and the first polarization direction is substantially perpendicular to the second polarization direction. The display panel can realize a normally black state, improve the contrast of a displayed image, and improve a display effect.
(FR) La présente invention concerne un panneau d’affichage et un procédé pour sa fabrication, et un appareil d’affichage. Le panneau d’affichage comporte: un premier substrat (100) et un second substrat (200) réfléchissant disposés l'un en face de l'autre; une couche (300) de cristaux liquides située entre le premier substrat (100) et le second substrat (200); une première couche polarisante (400) disposée d'un côté, à l'écart du second substrat (200), de la couche (300) de cristaux liquides; et une seconde couche polarisante (500) disposée entre la couche (300) de cristaux liquides et le second substrat (200), la seconde couche polarisante (500) étant configurée pour conférer à une lumière transmise une première direction de polarisation; dans le cas où aucune tension n'est appliquée à la couche (300) de cristaux liquides, une lumière transmise à travers la couche (300) de cristaux liquides et la première couche polarisante (400) présentant une seconde direction de polarisation; et la première direction de polarisation étant sensiblement perpendiculaire à la seconde direction de polarisation. Le panneau d’affichage peut réaliser un état normalement noir, améliorer le contraste d'une image affichée, et améliorer un effet d’affichage.
(ZH) 一种显示面板及其制备方法、显示装置。该显示面板包括:相对设置的第一基板(100)和反射式的第二基板(200);位于第一基板(100)和第二基板(200)之间的液晶层(300);设置在液晶层(300)的远离第二基板(200)一侧的第一偏光层(400);设置在液晶层(300)和第二基板(200)之间的第二偏光层(500),第二偏光层(500)配置为使得透过光具有第一偏振方向;在液晶层(300)未施加电压的情况下,透过液晶层(300)和第一偏光层(400)的光具有第二偏振方向,并且第一偏振方向和第二偏振方向基本垂直。该显示面板可以实现常黑态,提高显示图像的对比度,提高显示效果。
