相比于现有技术的阵列基板， 本发明的该第一实施例所示的 TFT-LCD 滤色器 /阵列基板具有用于实现滤色器功能的黑矩阵和蓝相液晶混合材料，这 样在包括该阵列基板 LCD 的制作工艺中， 省去了制作传统滤色器的工艺， 大大加快了 TFT-LCD的制作工艺过程， 且由于 TFT-LCD滤色器 /阵列基板 本身可以实现滤色器功能， 在与其它基板（如公共基板）对盒时， 减少和 / 或防止了传统的对盒工艺中的对盒偏差， 提高了图像质量。
在本发明的第二实施例中， 包括上述第一实施例所示结构的基础上， 所 述像素电极 19的电压为可调节的电压， 这样可以使涂覆于该像素电极 19上 的蓝相液晶混合材料中的蓝相液晶在该调节后的不同电压的驱动下， 呈现不 同角度的扭曲从而显示不同的颜色， 从而使阵列基板本身具有滤色器功能。
其中，在该第二实施例中， 所述像素电极 19所在的像素区域包括： 红色 像素区域、 蓝色像素区域以及绿色像素区域； 其中， 所述红色像素区域对应的像素电极的电压为第一电压， 所述蓝色 像素区域对应的像素电极的电压为第二电压， 所述绿色像素区域对应的像素 电极的电压为第三电压； 所述第一电压、 所述第二电压和所述第三电压各不 相同， 使所述红色像素区域的蓝相液晶混合材料显示红色， 所述蓝色像素区 域的蓝相液晶混合材料显示蓝色， 所述绿色像素区域的蓝相液晶混合材料显 示绿色， 从而使该阵列基板具有滤色器的三基色。
例如，在上述第一实施例和第二实施例中，所述蓝相液晶混合材料包括： 蓝相液晶 （BP-LC )和反应单体（RM ) 。
本发明的上述 TFT-LCD滤色器 /阵列基板实施例中， 用蓝相液晶混合材 料替代树脂材料， 利用 TFT驱动电压不同使得蓝相液晶完成不同程度的扭 曲， 得到 R, G, B子像素， 整个工艺过程只需进行一次曝光工艺， 大大加 快了工艺进程， 对整个面板制造工艺来说， 减少了传统工艺对盒精度偏差； 因为黑矩阵的良好对位， 提高了开口率； 亮度得到提高， 增强了图像的显示 质量。
如图 7所示， 本发明的第三实施例中， 还提供一种包括如上述图 1至图
6所示的 TFT-LCD滤色器 /阵列基板的液晶显示装置， 其中， 该液晶显示装 置还包括： 与所述 TFT-LCD滤色器 /阵列基板对盒的公共基板 24; 所述公共 基板 24的面对所述第一基板 11的表面上具有一公共电极 25; 所述蓝相液晶 混合材料 21、 22和 23中的蓝相液晶在所述像素电极 19和所述公共电极 25 之间的电场作用下发生扭曲。 又由于三种像素区域的蓝相液晶混合材料所在 的像素区域的驱动电压不同， 蓝相液晶呈现不同的颜色， 所以如果釆用相关 的控制单元控制驱动电压， 则可以使蓝相液晶分别呈现红、 蓝和绿三基色， 从而使阵列基板实现滤色器功能。
在本发明的该液晶显示装置的实施例中， TFT-LCD 滤色器 /阵列基板本 身具有滤色器功能， 从而在整个液晶显示装置的制作工艺中， 不再需要滤色 器的制作工艺， 节省了液晶显示装置的制作工艺流程， 减少了传统的对盒工 艺中的对盒偏差， 提高了图像质量； 又由于阵列基板本身的黑矩阵的良好对 位， 提高了开口率； 亮度得到提高， 增强了图像的显示质量。
例如，在该液晶显示装置中， 所述 TFT-LCD滤色器 /阵列基板为上基板。 再如图 1至图 6所示， 本发明的第四实施例还提供一种 TFT-LCD滤色 器 /阵列基板的制作方法， 包括：
步骤 1 : 如图 1所示， 在第一基板 11的一表面上形成阵列结构（图 1中 虚线所指示的部分）和像素电极 19;
步骤 2: 如图 2所示， 在所述阵列结构上形成黑矩阵 20;
步骤 3: 如图 3所示， 在所述像素电极上涂覆蓝相液晶混合材料 21、 22 和 23 , 并形成滤色器； 其中， 所述黑矩阵 20与所述像素电极 19间隔设置。
其中， 形成滤色器的过程包括：
如图 4所示， 调节所述像素电极 19的电压， 使所述像素电极 19对应的 像素区域的蓝相液晶混合材料呈现不同的颜色，即使得像素电极 19对应的像 素区域涂覆的蓝相液晶混合材料中的蓝相液晶呈现不同角度的扭曲， 从而使 不同的像素区域呈现不同的颜色。
具体来讲， 所述像素电极所在的像素区域包括： 红色像素区域、 蓝色像 素区域以及绿色像素区域； 其中， 所述红色像素区域对应的像素电极的电压 为第一电压， 所述蓝色像素区域对应的像素电极的电压为第二电压， 所述绿 色像素区域对应的像素电极的电压为第三电压； 调节所述第一电压、 所述第 二电压和所述第三电压，使所述红色像素区域的蓝相液晶混合材料显示红色 , 所述蓝色像素区域的蓝相液晶混合材料显示蓝色， 所述绿色像素区域的蓝相 液晶混合材料显示绿色。 其中， 所述蓝相液晶混合材料包括： 蓝相液晶和反 应单体。
例如， 本发明的该方法实施列还可进一步包括：
步骤 4: 如图 5所示， 利用汞（Hg )灯对像素区域 21、 22和 23进行照 射， 使得像素区域反射波长固定；
步骤 5: 如图 6所示， 利用紫外线（UV )灯对像素区域 21、 22和 23进 行照射， 使得反应单体聚合以固定像素区域的颜色；
步骤 6: 清洗步骤 5所得的本发明的实施例所述的 TFT-LCD滤色器 /阵 列基板， 由此得到具有滤色器的阵列基板， 该阵列基板的由蓝相液晶混合材 料形成的滤色器是反射型滤色器。
本发明实施例的该方法， 使用蓝相液晶混合材料为滤色器替代滤色器树 脂材料，利用 TFT驱动电压不同使得蓝相液晶呈现不同角度的扭曲而显示不 同的颜色， 再进行汞灯照射、 紫外照射以完成固色和聚合， 工艺过程简单， 仅需要一次曝光工艺， 对整个面板工艺来说， 在阵列基板上制作工艺简单的 滤色器， 大大提高了开口率， 同时， 也提高对盒精度， 提高良率。
以上所述仅是本发明的示范性实施方式， 而非用于限制本发明的保护范 围， 本发明的保护范围由所附的权利要求确定。
