【背景技术】
液晶面板是液晶显示装置中的重要组件， 主要包括： 阵列基板、 彩膜基板 以及设置在阵列基板和彩膜基板之间的液晶分子。
如图 1所示， 现有液晶面板的结构中， 液晶电容 CLC (像素电极与共用电 极之间的电容） 由阵列基板 20 ( Array )侧的像素电极 24 ( ITO电极）和彩膜基 板 10 ( CF )侧的共用电极 14 ( ITO电极）共同形成， 间隙粒子 13形成在黑矩 阵 12之上， 黑矩阵 12之间是彩色滤光膜 11 , 其中彩膜基板 10侧的共用电极 14需要与阵列基板 20上的像素电极 24形成电气连接。 目前， 业界之方法一般 为在阵列基板侧 AA区（可视区）外的框胶 ( sealant )区域内制作中转区（ transfer pad ) , 然后在液晶盒制程阶段进行金球（ Au ball )撒布， 以形成像素电极与共用 电极之间的电气连接。 如图 1所示， 所述电气连接通过撒布在框胶 15内的中转 区内的金球 16实现， 也就是说， 金球 16与阵列基板 20上的像素电极 24电气 连接， 同时又与彩膜基板 10上的共用电极 14电气连接。 这就要求在光罩设计 时即需考虑中转区 （transfer pad )之放置， 且金球（ Au ball )亦为液晶盒制程段 材料消耗成本之一。
如图 2所示，现有液晶面板的彩膜基板的一般制程是,在制作完黑矩阵（ BM、 Black Matrix ) 以及彩色滤光膜（R、 G、 B )子像素之后， 制作 ITO薄膜， 再形 成间隙粒子（PS、 Photo Spacer ), 其作用是支撑两层玻璃基板和控制液晶盒的沟 壑。 然后于液晶盒制程段再将金球（Au ball )撒布于彩膜基板上。

一种彩膜基板的制造方法， 包括步骤：
A: 在彩膜基板上形成黑矩阵和彩色滤光膜，
B: 形成间隙粒子，
C: 形成公共电极层。
一种液晶面板， 包括对置的阵列基板和彩膜基板， 所述彩膜基板上形成有 间隙粒子以及公共电极层， 所述间隙粒子与所述阵列基板相对的表面有所述公 共电极层覆盖； 所述间隙粒子上的公共电极层与所述液晶面板上的阵列基板的 像素电极信号连接。
优选的， 所述彩膜基板的框胶设置区也设置有间隙粒子， 其上表面也有所 述公共电极层覆盖。 使得间隙粒子的表面具有电极层， 从而使间隙粒子能够代 替金球进行导电。
优选的， 所述间隙粒子上的公共电极层与所述液晶面板上的阵列基板的像 素电极接触以信号连接。 使得间隙粒子能够将阵列基板的信号传递至彩膜基板。
优选的， 所述电极层为 ITO材料制成。 ITO材料为较优的电极材料， 其材 质透明， 不影响像素的透光性。
一种液晶显示装置， 包括了上述的液晶面板。
本发明由于利用间隙粒子与阵列基板和彩膜基板均有接触的条件， 将间隙 粒子的制程与电极层的制程替换， 使得间隙粒子先形成于彩膜基板上， 再进行 电极层的形成， 使得间隙粒子的与阵列基板相对的表面上也覆盖有电极层， 这 样， 间隙粒子就可以将阵列基板上的像素电极信号传递到彩膜基板， 代替了金 球的作用， 从而在液晶面板的制造工艺中， 可以省去金球的撒布工艺以及中转 区的光罩设计， 更省去了金球的材料需求。
