具体实施方式
为更进一步阐述本发明为达成预订发明目的所采取的技术手段及功效，以下结合附图及较佳实施例，对依据本发明提出的彩色滤光片整合晶体管式液晶面板及其制造方法其具体实施方式、结构、特征及其功效，详细说明如后。
请参照图1，其为本发明一实施例中彩色滤光片整合晶体管式液晶面板1的构造示意图。所述彩色滤光片整合晶体管式液晶面板1包含一第一基板10、一第二基板20、一液晶层30及若干间隙柱40。所述第一基板10与第二基板20相对设置，且所述液晶层30夹设于所述第一基板10与第二基板20之间。所述第一基板10的内表面上具有一第一配向膜(图中未示出)，所述第二基板20的内表面上具有一第二配向膜(图中未示出)。所述液晶层30接触所述第一配向膜及所述第二配向膜。
所述第一基板10包括一第一透明基板101、一薄膜晶体管阵列层102、一第一保护层103、一彩色滤光层104、一第二保护层105及若干第一透明导电膜106。所述薄膜晶体管阵列层102是设置于所述第一透明基板101的内表面上。所述第一保护层103是设置于所述薄膜晶体管阵列层102上。所述彩色滤光层104是设置于所述第一保护层103上。所述第二保护层105是设置于所述彩色滤光层104上。所述若干第一透明导电膜106是设置于所述第二保护层105上。
所述第二基板20包括一第二透明基板201、一黑色矩阵层202及一第二透明导电膜203。所述黑色矩阵层202是设置于所述第二透明基板201的内表面上。所述第二透明导电膜203是设置于所述黑色矩阵层202上。所述若干间隙柱40是设置于所述彩色滤光层104及所述黑色矩阵层202之间。
所述液晶层30包含至少一种极性液晶单体和至少一种非极性液晶单体。所述液晶层30的液晶分子为负性液晶，并且所述液晶层30的液晶分子的介电常数(△ε)在20℃下是介于-2.1～-2.5之间。
由一偏振光敏感材料构成的所述第一及第二配向膜是通过紫外线诱导多区域垂直配向(UV2A)的光配向技术而形成的。所述偏振光敏感材料是一反应波长为313nm的聚酰亚胺材料，且所述聚酰亚胺材料的配向基团包含肉桂酸、香豆素。
请参照图2，其为本发明一实施例中彩色滤光片整合晶体管式液晶面板1的制造方法的步骤流程图，该制造方法包括下述步骤S11至S14。
在步骤S11中，提供一第一基板10。所述第一基板10包含一透明基板101、一设置于所述透明基板101上的薄膜晶体管阵列层102及一设置于所述薄膜晶体管阵列层102上的彩色滤光层104。
在步骤S12中，提供一第二基板20。
在步骤S13中，分别涂布一偏振光敏感材料在所述第一基板10及所述第二基板20上，而后通过紫外线诱导多区域垂直配向(UV2A)的光配向技术来相应地形成一第一配向膜及一第二配向膜(图中未示出)。所述偏振光敏感材料是一反应波长为313nm的聚酰亚胺材料，且所述聚酰亚胺材料的配向基团包含肉桂酸、香豆素。所述紫外线诱导多区域垂直配向(UV2A)的光配向技术的具体特征为，紫外偏振光为倾斜入射至一配向膜，然后所述配向膜会沿着所述紫外偏振光的入射方向而倾倒，亦即，可以通过控制不同的入射光的方向，来控制配向膜的配向方向，从而控制液晶的倒向，如图3所示。
在步骤S14中，提供至少一种极性液晶单体和至少一种非极性液晶单体，且混合所述极性液晶单体及所述非极性液晶单体，而后填充在所述第一基板10及所述第二基板20之间，形成一液晶层30。所述液晶层30接触所述第一配向膜和所述第二配向膜。所述液晶层30的液晶分子为负性液晶，且所述液晶层的液晶分子的介电常数(△ε)在20℃下是介于-2.1～-2.5之间。
通过执行上述步骤S11至S14，即可制作出本发明的彩色滤光片整合晶体管式液晶面板。
请参照表1，其是本发明的具体实例中不同液晶配方的介电常数(△ε)。具有单体A～C和单体a～d的液晶混合物LC-1的介电常数(△ε)为-3.5。具有单体A～E和单体a～b的液晶混合物LC-2的介电常数(△ε)为-2.7。具有单体A～C及E和单体a～b及d的液晶混合物LC-3的介电常数(△ε)为-2.1。因此，可以得知，通过液晶配方的调整(亦即，不同的极性液晶单体和不同的非极性液晶单体的选取)，可以获得不同的介电常数(△ε)。另外，也可通过调整单体的含量来控制其介电常数(△ε)。
[表1]
接着，请参照图4，其是表4的不同液晶配方的影像残留表现。在此，以不同时间的JND表示。JND无时以1.7表示，其是最佳。JND数值越大，影像残留表现越差。从图4中可以看出随着介电常数(△ε)变大，影像残留表现越来越好。因此，可以得知，通过控制液晶的介电常数(△ε)可以改善液晶的影像残留表现。
如上所述，本发明的彩色滤光片整合晶体管式液晶面板及其制造方法是通过以紫外线诱导多区域垂直配向(UV2A)的光配向技术形成所述彩色滤光片整合晶体管式液晶面板中的配向膜，以及通过控制所述彩色滤光片整合晶体管式液晶面板中液晶层的液晶分子的介电常数(△ε)，来改进现有彩色滤光片整合晶体管式液晶显示器的影像残留的问题。
本发明已由上述相关实施例加以描述，然而上述实施例仅为实施本发明的范例。必需指出的是，已公开的实施例并未限制本发明的范围。相反地，包含于权利要求书的精神及范围的修改及均等设置均包括于本发明的范围内。
