液晶显示面板构造及其制作方法 技术领域
本发明涉及一种液晶显示面板构造及其制作方法，特别是涉及一种通过在配向膜表面设置光感反应单体以固定液晶分子的水平取向的一种液晶显示面板构造及其制作方法。
 背景技术
液晶显示器是目前使用最广泛的一种平板显示器，已经逐渐成为各种电子设备如移动电话、个人数字助理(PDA)、数字相机、计算机屏幕或笔记本电脑屏幕所广泛应用具有高分辨率彩色屏幕的显示器。 目前普遍采用的液晶显示器，通常有上下基板和中间液晶层组成，上下基板则由玻璃基板和电极等组成。如果上下基板都有电极，可以形成纵向电场模式的显示器，如TN(Twist Nematic)模式、VA(Vertical Alignment)模式以及为了解决视角过窄而开发的MVA(Multi-Domain Vertical Alignment) 模式。另外一类显示器是将电极只设置于下基板侧，形成横向电场模式的显示器，如IPS(In-Plane Switching)模式及FFS(Fringe Field Switchin；边缘电场切换)模式等。
上述FFS的液晶驱动模式为IPS平面转换型液晶驱动模式所衍伸出来的广视角技术，在其结构设计上，FFS模式是在电极间距下方设置一般电极，施加电压就会产生边界电场使液晶在电极上旋转，藉由边界电场使几乎均质排列的液晶分子在电极表层内部旋转，达到高穿透性与大视角特性。这种电场分布在z方向有较大的分量，可以调变液晶分子的面积也较大，这样的电极分布设计大幅提升了施加驱动电压后液晶平面显示器中液晶分子扭转动力，改善了IPS广视角技术扭转速度慢，且开口率低，需要较多的背光源等缺点，另外FFS面板也是广视角技术中视角最广的技术。
再者，FFS液晶显示器使用的配向方法有很多，摩擦配向是使用最广泛的一种。摩擦配向不但具有优良光学特性，而且在高温条件下的可靠性也很好。然而，由于摩擦配向依靠配向层与毛布的机械摩擦配向，配向膜表面的液晶分子均匀性较差，容易引起暗态漏光，影响液晶显示器的对比度。 例如，请参照图1A至1C所示，其揭示一种现有的液晶显示面板构造的组装示意图。此一现有的液晶显示面板构造10是属于边缘电场切换型(FFS)的液晶显示面板，其主要包含一阵列基板(Array Substrate)、一彩色滤光片基板(Color Filter Substrate)及一液晶层(Liquid Crystal Layer)，其组装制作方式如下：
(a) 请参照图1A：设置一第一基板11，其包含一第一配向膜11a，所述第一配向膜11a形成于所述第一基板11的上表面，并以磨擦轮A对所述第一基板11的第一配向膜11a实施摩擦配向；
(b) 请参照图1B：设置一第二基板12，其包含一第二配向膜12a，所述第二配向膜12a形成于所述第二基板12的上表面，并以磨擦轮A对所述第二基板12的第二配向膜12a实施摩擦配向；
(c) 请参照图1C：对应组装所述第一基板11与所述第二基板12，使所述第一基板11的第一配向膜11a与所述第二基板12的第二配向膜12a分别向内对应，接着灌注一液晶层13于所述第一基板11及所述第二基板12之间(即所述第一配向膜11a及所述第二配向膜12a之间)，其中所述液晶层13包含多个液晶分子13a，然而由于所述第一基板的第一配向膜11a与所述第二基板的第二配向膜12a的配向作用，所述多个液晶分子13a的排列会在水平方向(所述液晶层130的水平方向)上具有一预倾角θ。
综上所述，现有的边缘电场切换型(FFS)的液晶显示面板的组装制作方式会使所述液晶显示面板构造100内的液晶分子13a产生预倾角，从而影响液晶显示器的对比度。
因此，有必要提供一种液晶显示面板构造及其制作方法，以解决现有边缘电场切换型的液晶显示面板所存在的问题。

请参照图4所示，本发明第三实施例的一种液晶显示面板构造的示意图。本发明第三实施例的液晶显示面板构造与本发明第二实施例大致相同，因此沿用相同的标记符号，但本发明第三实施例的液晶显示面板构造30’与第二实施例的液晶显示面板构造30的主要不同之处在于：所述第一基板31’具有两个透明导电层，其中第一透明导电层31a是一像素电极层，另一个透明导电层31c是一公共电极层，所述像素电极层及公共电极层两者之间夹设有一保护层31d。因此，在进行通电程序时，所述液晶显示面板构造30’的所述两个透明导电层31a, 31c(所述像素电极层及所述公共电极层)都会施加同一极性的电压，也就是所述像素电极层及所述公共电极层在电路上形成一并联的关系，从而可进一步提高通电时产生垂直电场效率。

    (g) 对所述第一基板的第一透明导电层及所述第二基板的第二透明导电层进行一通电程序，使在所述第一基板和所述第二基板之间形成一垂直电场;
    (h) 在施加所述垂直电场的同时施加一紫外线照射，使所述第一基板的第一配向膜及所述第二基板的第二配向膜各自的所述多个光感反应单体发生作用，以固定所述液晶层的多个液晶分子的取向，消除所述液晶分子的预倾角，使所述多个液晶分子相对所述液晶层的取向为水平; 及
    (i) 撤除所述垂直电场与所述紫外线照射，所述多个液晶分子的取向仍保持为水平。
  13. 如权利要求12所述的液晶显示面板构造的制作方法，其中所述第一基板是一阵列基板；及所述第二基板是一彩色滤光片基板。
  14. 如权利要求12所述的液晶显示面板构造的制作方法，其中所述第一透明导电层是一像素电极层，所述第一配向膜设于所述像素电极层上。
  15. 如权利要求12所述的液晶显示面板构造的制作方法，其中所述第二透明导电层是一静电屏蔽层，设于所述第二基板的一背面。
  16. 如权利要求12所述的液晶显示面板构造的制作方法，其中所述第一基板具有两个所述第一透明导电层，包含一像素电极层及一公共电极层，所述像素电极层及公共电极层两者之间夹设有一保护层。
  17. 如权利要求12所述的液晶显示面板构造的制作方法，其中所述通电程序是施加直流电或交流电的通电程序。
