Title (EN) COLOR FILTER AND METHOD FOR MANUFACTURE THEREOF
(FR) FILTRE COLORÉ ET SON PROCÉDÉ DE FABRICATION
(ZH) 一种彩色滤光片及其制作方法
Abstract:
(EN) A color filter and a method for manufacture thereof are disclosed. The method comprises: forming a black matrix (20) on a substrate (10); by means of a first mask (100), forming a first color resistor (31) on the substrate (10) and forming a first spacer part (32) on the black matrix (20); by means of a second mask (200), forming a second color resistor (41) arranged with an interval from the first color resistor (31) on the substrate (10) and forming a second spacer part (42) on the first spacer part (32); and by means of a third mask (300), forming a third color resistor (51) arranged with an interval from either of the first color resistor (31) and the second color resistor (41) on the substrate (10). The black matrix (20), the first spacer part (32) and the second spacer part (42) overlap to form a spacer for the color filter, thereby forming the spacer without extra manufacture processes of masks, reducing the manufacture cost, and the spacer not sliding down into light-transmitting areas of pixels to induce the Mura phenomenon when panels are pressed.
(FR) La présente invention concerne un filtre coloré et son procédé de fabrication. Le procédé comprend les étapes consistant à : former une matrice noire (20) sur un substrat (10) ; au moyen d'un premier masque (100), former une première résistance de couleur (31) sur le substrat (10) et former une première partie d'espaceur (32) sur la matrice noire (20) ; au moyen d'un deuxième masque (200), former sur le substrat (10) une deuxième résistance de couleur (41) disposée avec un intervalle à partir de la première résistance de couleur (31) et former une seconde partie d'espaceur (42) sur la première partie d'espaceur (32) ; et, au moyen d'un troisième masque (300), former sur le substrat (10) une troisième résistance de couleur (51) disposée avec un intervalle à partir de la première résistance de couleur (31) et de la deuxième résistance de couleur (41). La matrice noire (20), la première partie d'espaceur (32) et la seconde partie d'espaceur (42) se chevauchent de manière à former un espaceur destiné au filtre coloré, ce qui permet de former l'espaceur sans autre processus de fabrication de masques, de réduire le coût de fabrication et d'empêcher l'espaceur de glisser vers le bas dans des zones de transmission de lumière faisant partie de pixels, ce qui provoque le phénomène de moiré lorsque les panneaux sont comprimés.
(ZH) 公开了一种彩色滤光片及其制作方法,方法包括:在基板(10)上形成黑色矩阵(20);通过第一掩膜板(100)在基板(10)上形成第一色阻(31)以及在黑色矩阵(20)上形成第一间隔部(32);通过第二掩膜板(200)在基板(10)上形成与第一色阻(31)间隔排列的第二色阻(41)以及在第一间隔部(32)上形成第二间隔部(42);通过第三掩膜板(300)在基板(10)上形成与第一色阻(31)、第二色阻(41)间隔排列的第三色阻(51)。黑色矩阵(20)、第一间隔部(32)和第二间隔部(42)重叠后形成彩色滤光片的隔垫物。以这种方式,不需要额外的光罩制程来制造隔垫物,减少了制造成本,且当面板受到挤压时,隔垫物不会滑落入像素的透光区从而造成mura状况。
