具体实施方式
为使本发明实施例的目的、 技术方案和优点更加清楚， 下面将结合本发 明实施例的附图，对本发明实施例的技术方案进行清楚、 完整地描述。显然， 所描述的实施例是本发明的一部分实施例， 而不是全部的实施例。 基于所描 述的本发明的实施例， 本领域普通技术人员在无需创造性劳动的前提下所获 得的所有其他实施例， 都属于本发明保护的范围。
本发明实施例提供了一种彩膜基板， 如图 1所示， 该彩膜基板 1包括多 个用于滤光并分别对应一像素的像素滤光膜 2, 像素滤光膜可以有三种， 例 如为红色像素滤光膜、 绿色像素滤光膜或蓝色像素滤光膜， 但不限于所述种 类数量及其色彩组合。 所述彩膜基板 1上设置有遮光隔垫物 8, 所述遮光隔 垫物 8延伸至所有相邻的所述像素滤光膜 2之间的间隙区域并覆盖全部所述 间隙区 i或。
在本发明实施例中，彩膜基板可以是边缘场开关（ Fringe Field Switching, FFS )型的彩膜基板、 扭曲向列 （ Twisted Nematic,TN )型的彩膜基板或者其 他类型的彩膜基板。 例如， 在 FFS型的彩膜基板上， 遮光隔垫物设置在 FFS 型的彩膜基板的平坦保护层上； 在 TN型的彩膜基板上， 遮光隔垫物设置在 TN型的彩膜基板的公共电极上。
相对于现有技术中在彩膜基板中釆用黑矩阵实现对像素滤光膜之间的间 隙 （对应于阵列基板中的栅线和数据线） 的遮光作用， 本发明实施例釆用遮 光隔垫物代替黑矩阵起到遮光作用， 同时遮光隔垫物又能起到对液晶面板盒 的支撑作用， 从而取代了现有技术中的普通隔垫物。
本发明实施例釆用的遮光隔垫物是通过减小相邻像素滤光膜间隙处液晶 的光学延迟量来取代原来黑矩阵的遮光效果。 如图 2所示， 随着光学延迟量 △ n d (图中每一条曲线表示一个光学延迟量数值的光线）的变化， 各个波长 (图中所示 λ )的光的透过率（图中所示 y轴）都产生变化。 图 2表明， 当光 学延迟量 An d较低时， 其光透过率也较低， 随着光学延迟量的增加， 光的透 过率也不断增加。 因此， 本发明实施例利用减小相邻像素滤光膜的间隙区域 的液晶厚度， 来减小该区域的光学延迟量（ An d ) , 进而减小该区域的光线 透过率， 从而起到遮光的作用。
并且， 由于液晶面板的下偏光片为 90度， 上偏光片为 0度， 光在通过液 晶层时， 不会发生光偏振方向的改变， 因此， 通过阵列基板的像素电极（即 对应于彩膜基板上的像素滤光膜 ) 的光不会通过遮光隔垫物从相邻像素滤光 膜的间隙区域穿过， 因此， 本发明实施例在相邻像素滤光膜的间隙区域加入 遮光隔垫物可以有效起到遮光作用。
本发明实施例提供的彩膜基板， 在彩膜基板上设置遮光隔垫物， 通过减 小相邻像素滤光膜间隙区域液晶的光学延迟量来实现对于该区域的遮光效 果， 取代了现有技术中釆用的黑矩阵， 并且同时又能起到对液晶面板盒厚的 支撑作用。 相对于现有技术中具有黑矩阵的液晶显示面板， 本发明实施例提 供的液晶显示面板在制作时， 省去了黑矩阵的光刻掩膜生产步骤， 在制作隔 垫物时即可完成遮光隔垫物的制备， 减少了彩膜基板的制备工序， 降低了液 晶显示面板的生产成本。 由于像素滤光膜直接设置在玻璃基板上， 而不是如 现有技术中那样设置在黑矩阵层上， 因此， 简化了像素滤光膜的制作工序， 进而提高了生产效率。
本发明实施例提供了一种液晶显示面板， 如图 3所示， 该液晶显示面板 包括：
阵列基板 4和彩膜基板 1 , 所述彩膜基板 1包括有多个用于滤光并分别 对应一像素的像素滤光膜 2。 像素滤光膜可以有三种， 例如为红色像素滤光 膜、 绿色像素滤光膜或蓝色像素滤光膜， 但不限于所述种类数量及其色彩组 合。 所述彩膜基板 1上设置有第一遮光隔垫物 3 , 所述第一遮光隔垫物 3延 伸至所有相邻的所述像素滤光膜 2之间的间隙区域并覆盖全部所述间隙区 域，即第一遮光隔垫物 3遮挡在所有相邻的像素滤光膜 2之间的间隙区域上，
所述第一遮光隔垫物 3的一端抵靠于所述阵列基板 4上。
在本发明实施例中， 彩膜基板可以是边缘场开关型的彩膜基板、 扭曲向 列型的彩膜基板或者其他类型的彩膜基板。 例如， 在 FFS型的彩膜基板上， 第一遮光隔垫物 3设置在 FFS型的彩膜基板的平坦保护层上； 在 TN型的彩 膜基板上， 第一遮光隔垫物 3设置在 TN型的彩膜基板的公共电极上。
相对于现有技术中在彩膜基板中釆用黑矩阵实现对像素滤光膜之间的间 隙 （对应于阵列基板中的栅线和数据线） 的遮光作用， 本发明实施例釆用第 一遮光隔垫物代替黑矩阵起到遮光作用， 同时由于第一遮光隔垫物 3的一端 抵靠在阵列基板 4上， 使得第一遮光隔垫物又能起到对液晶面板盒的支撑作 用， 从而取代了现有技术中的普通隔垫物。
本发明实施例釆用的第一遮光隔垫物是通过减小相邻像素滤光膜间隙处 液晶的光学延迟量来取代原来黑矩阵的遮光效果， 当光学延迟量较低时， 光 的透过率也较低， 随着光学延迟量的增加， 光的透过率也不断增加。 因此， 本发明实施例利用减小相邻像素滤光膜的间隙区域的液晶厚度， 来减小该区 域的光学延迟量， 进而减小该区域的光线透过率， 从而起到遮光的作用。
并且， 由于液晶面板的下偏光片为 90度， 上偏光片为 0度， 光在通过液 晶层时， 不会发生光偏振方向的改变， 因此， 通过阵列基板的像素电极（即 对应于彩膜基板上的像素滤光膜 ) 的光不会通过第一遮光隔垫物从相邻像素 滤光膜的间隙区域穿过， 因此， 本发明实施例在相邻像素滤光膜的间隙区域 加入第一遮光隔垫物可以有效起到遮光作用。
本发明实施例提供的液晶显示面板，在彩膜基板上设置第一遮光隔垫物， 并且第一遮光隔垫物的一端抵靠于阵列基板上， 通过减小相邻像素滤光膜间 隙区域液晶的光学延迟量来实现对于该区域的遮光效果， 取代了现有技术中 釆用的黑矩阵， 并且同时又能起到对液晶面板盒厚的支撑作用。 相对于现有 技术中具有黑矩阵的液晶显示面板， 本发明实施例提供的液晶显示面板在制 作时， 省去了黑矩阵的光刻掩膜生产步骤， 在制作隔垫物时即可完成第一遮 光隔垫物的制备， 减少了彩膜基板的制备工序， 降低了液晶显示面板的生产 成本。 由于像素滤光膜直接设置在玻璃基板上， 而不是如现有技术中那样设 置在黑矩阵层上， 因此， 简化了像素滤光膜的制作工序， 进而提高了生产效 率。
进一步的， 在本发明实施例中， 所述第一遮光隔垫物 3的位置与所述阵 列基板 4上所形成的栅线、 数据线和薄膜晶体管正对。 即第一遮光隔垫物 3 的一端覆盖在所有相邻的像素滤光膜 2之间的间隙区域上， 另一端则抵靠在 阵列基板 4上的栅线、 数据线和薄膜晶体管上。
第一遮光隔垫物 3的上端面 (图中所示第一遮光隔垫物 3靠近彩膜基板
1一侧的端面 )设置在所述彩膜基板 1上， 并且该上端面正对于相邻的像素 滤光膜 2之间的间隙区域， 第一遮光隔垫物 3的下端面 （图中所示第一遮光 隔垫物 3靠近阵列基板 4一侧的端面 )分别覆盖在所述阵列基板 4的栅线、 数据线和薄膜晶体管上。 第一遮光隔垫物 3在栅线、 数据线和薄膜晶体管上 都有覆盖， 其整体成方格网状结构。 第一遮光隔垫物 3釆用比普通隔垫物柔 软的树脂材料， 可以保证第一遮光隔垫物 3的下端面可以弹性地紧密覆盖在 所述阵列基板 4上， 在阵列基板和彩膜基板对盒封装后， 栅线、 数据线和薄 膜晶体管对应的区域（即遮光区） 的液晶层厚度为 0 , 从而使得该遮光区的 光学延迟量为 0, 进而达到良好的遮光效果。
可选的， 本发明实施例还提供另一种实施方案， 如图 4和图 5所示， 液 晶显示面板包括： 阵列基板 4和彩膜基板 1 , 所述彩膜基板 1包括有多个用 于滤光并分别对应一像素的像素滤光膜 2。 所述彩膜基板 1上设置有第一遮 光隔垫物 3 , 所述第一遮光隔垫物 3延伸至所有相邻的所述像素滤光膜 2之 间的间隙区域并覆盖全部所述间隙区域， 所述阵列基板 4上形成有第二遮光 隔垫物 5 , 所述第一遮光隔垫物 3的一端 ·ί氏靠于所述第二遮光隔垫物 5上。
进一步的， 所述第二遮光隔垫物 5的位置与所述阵列基板 4上所形成的 栅线、 数据线和薄膜晶体管正对。 在阵列基板 4上设置第二遮光隔垫物 5 , 通过第二遮光隔垫物 5对栅线、 数据线和薄膜晶体管实现全面的覆盖， 通过 第二遮光隔垫物 5和第一遮光隔垫物 3共同的遮挡， 进一步防止遮光区域的 漏光， 提高遮光效果。
第二遮光隔垫物 5和第一遮光隔垫物 3相 ·ί氏靠具体为： 所述第二遮光隔 垫物 5的下端面分别设置在所述阵列基板 4的栅线、数据线和薄膜晶体管上， 所述第一遮光隔垫物 3的上端面设置在所述彩膜基板 1上， 并且该上端面完 全覆盖在彩膜基板 1上所有相邻的所述像素滤光膜 2之间的间隙区域， 所述 第一遮光隔垫物 3的下端面与所述第二遮光隔垫物 5的上端面相 4氏靠。 第一
遮光隔垫物 3和 /或第二遮光隔垫物 5釆用比普通隔垫物柔软的树脂材料，第 一遮光隔垫物 3的下端面可以弹性地紧密贴合第二遮光隔垫物 5的上端面， 两者相抵靠， 对液晶面板盒起到支撑的作用。 在阵列基板和彩膜基板对盒封 装后， 栅线、 数据线和薄膜晶体管对应的区域（即遮光区） 的液晶层厚度为 0, 从而使得该遮光区的光学延迟量为 0, 进而达到良好的遮光效果， 并且由 于第二遮光隔垫物 5对于栅线、 数据线和薄膜晶体管的覆盖， 可以进一步防 止来自阵列基板的漏光， 从而提高遮光效果。
可选的， 在本发明的一个实施例中， 所述第一遮光隔垫物和所述第二遮 光隔垫物为不透光的树脂材料。 釆用不透光的树脂材料可以进一步防止遮光 区域由于遮光隔垫物材料本身所造成的漏光， 从而提高遮光效果。
本发明实施例提供的液晶显示面板，在彩膜基板上设置第一遮光隔垫物， 在阵列基板上设置第二遮光隔垫物， 通过减小相邻像素滤光膜间隙区域液晶 的光学延迟量来实现对于该区域的遮光效果， 并且由于第二遮光隔垫物对于 栅线、 数据线和薄膜晶体管的覆盖， 可以进一步防止来自阵列基板的漏光， 提高了遮光效果， 取代了现有技术中釆用的黑矩阵， 并且同时又能起到对液 晶面板盒厚的支撑作用。 相对于现有技术中具有黑矩阵的液晶显示面板， 本 发明实施例提供的液晶显示面板在制作时， 省去了黑矩阵的光刻掩膜生产步 骤， 在制作隔垫物时即可完成第一遮光隔垫物的制备， 减少了彩膜基板的制 备工序， 降低了液晶显示面板的生产成本。 由于像素滤光膜直接设置在玻璃 基板上， 而不是如现有技术中那样设置在黑矩阵层上， 因此， 简化了像素滤 光膜的制作工序， 进而提高了生产效率。
基于上述实施例， 本发明实施例提供了一种液晶显示面板的制造方法， 所述液晶显示面板包括阵列基板和形成有多个用于滤光并分别对应一像素的 像素滤光膜的彩膜基板， 该方法包括下述步骤：
101、在所述彩膜基板上形成第一遮光隔垫物，所述第一遮光隔垫物延伸 至所有相邻的所述像素滤光膜之间的间隙区域并覆盖全部所述间隙区域， 所 述第一遮光隔垫物围出有多个区域；
102、将液晶注入彩膜基板的第一遮光隔垫物所围出的每一个区域，并将 所述彩膜基板和所述阵列基板封装成盒。
在本发明实施例中， 彩膜基板可以是边缘场开关型的彩膜基板、 扭曲向
列型的彩膜基板或者其他类型的彩膜基板。 例如， 形成 FFS型的彩膜基板具 体为： 如图 6所示， 在玻璃基板 6上形成各种颜色的像素滤光膜 2; 如图 7 所示， 在像素滤光膜 2上形成平坦保护层 7; 如图 8所示， 在平坦保护层 7 上形成第一遮光隔垫物 3 ,使得第一遮光隔垫物 3正对于相邻的像素滤光膜 2 之间的间隙区域。 在 TN型的彩膜基板上， 第一遮光隔垫物 3形成在 TN型 的彩膜基板的公共电极上， 但同样使得第一遮光隔垫物 3正对于相邻的像素 滤光膜 2之间的间隙区域。

进一步的， 在本发明实施例中， 所述第一遮光隔垫物的位置与所述阵列 基板上所形成的栅线、 数据线和薄膜晶体管正对。 所述第一遮光隔垫物的上 端面设置在所述彩膜基板上， 并且该上端面正对于相邻的所述像素滤光膜之 间的间隙区域， 所述第一遮光隔垫物的下端面分别覆盖在所述阵列基板的栅 线、 数据线和薄膜晶体管上。
