Title
(EN) COLOR FILM SUBSTRATE AND LIQUID CRYSTAL DISPLAY PANEL
(FR) SUBSTRAT DE FILM COLORÉ ET ÉCRAN D'AFFICHAGE À CRISTAUX LIQUIDES
(ZH) 彩膜基板及液晶显示面板
Abstract
(EN)
Provided are a color film substrate and a liquid crystal display panel. The color film substrate comprises a plurality of photoresist blocks (10) that is spaced apart, black matrixes (20) provided between adjacent photoresist blocks (10), optically rarer medium films (30) provided on the plurality of photoresist blocks (10) and the black matrixes (20), and a planarization layer (40) covering the plurality of photoresist blocks (10), the black matrixes (20), and the optically rarer medium layers (30). The optically rarer medium films (30) cover junctions between the plurality of photoresist blocks (10) and the black matrixes (20). The refractive index of the optically rarer medium films (30) is smaller than that of the planarization layer (40). After forming a liquid crystal display panel by assembling the color film substrate and a TFT array substrate (9), during large-view observation, total internal reflection of light rays emitted from a pixel unit (91) to a photoresist block (10) adjacent to the photoresist block (10) corresponding to the pixel unit (91) would occur on interfaces between the planarization layer (40) and the optically rarer medium films (30), thereby resolving the problem of large-view color cast without affecting the transmittance of the liquid crystal display panel.

L'invention concerne un substrat de film coloré et un écran d'affichage à cristaux liquides. Le substrat de film coloré comprend une pluralité de blocs de résine photosensible (10) qui sont espacés, des matrices noires (20) disposées entre des blocs de résine photosensible adjacents (10), des films de support optiquement rares (30) disposés sur la pluralité de blocs de résine photosensible (10) et les matrices noires (20), et une couche de planarisation (40) recouvrant la pluralité de blocs de résine photosensible (10), les matrices noires (20) et les couches de support optiquement rares (30). Les films de support optiquement rares (30) couvrent des jonctions entre la pluralité de blocs de résine photosensible (10) et les matrices noires (20). L'indice de réfraction des films de support optiquement rares (30) est inférieur à celui de la couche de planarisation (40). Après la formation d'un écran d'affichage à cristaux liquides par assemblage du substrat de film coloré et d'un substrat de réseau TFT (9), pendant une observation de grand angle, une réflexion interne totale de rayons lumineux émis à partir d'une unité de pixel (91) vers un bloc de résine photosensible (10) adjacent au bloc de résine photosensible (10) correspondant à l'unité de pixel (91) se produirait sur des interfaces entre la couche de planarisation (40) et les films de support optiquement rares (30), ce qui permet de résoudre le problème de dominance de couleur de large vue sans altérer la transmittance de l'écran d'affichage à cristaux liquides.

提供一种彩膜基板及液晶显示面板。彩膜基板包括相间隔的多个光阻块(10)、设于相邻的光阻块(10)之间的黑色矩阵(20)、设于多个光阻块(10)及黑色矩阵(20)上的光疏介质膜(30)以及覆盖多个光阻块(10)、黑色矩阵(20)及光疏介质膜(30)的平坦化层(40),光疏介质膜(30)覆盖多个光阻块(10)与黑色矩阵(20)的交界处,光疏介质膜(30)的折射率小于平坦化层(40)的折射率。利用彩膜基板与TFT阵列基板(9)对组形成液晶显示面板后,大视角观看时,一像素单元(91)射入与像素单元(91)对应的光阻块(10)相邻的光阻块(10)的光线会在平坦化层(40)与光疏介质膜(30)的交界面发生全反射,从而在不影响液晶显示面板的穿透率的基础上解决了大视角色偏的问题。
