以下将参照相关图式，说明依本申请实施例的液晶显示装置，其中相同的元件将以相同的参照符号加以说明。
图1为本申请一实施例的液晶显示装置2的示意图。如图1所示，本实施例的液晶显示装置2包括一第一基板21、一第一垂直配向层22、一第二基板23、一第二垂直配向层24与一液晶层25。
本实施例的液晶显示装置2以应用多区域垂直配向(Multi-domain Vertical Alignment,MVA)技术的液晶显示面板为例，并且液晶层25的液晶以n型液晶，也就是具有负介电常数异向性的液晶为例，但本申请并不限于此应用。
第一基板21与第二基板23相对设置，且液晶层25设置于第一基板21与第二基板23之间。在本实施例中，第一基板21以彩色滤光基板(CF substrate)为例，第二基板23以薄膜晶体管基板(TFT substrate)为例。
第一基板21例如包括一玻璃基板、一彩色滤光层以及一黑色矩阵层，由于这些构件可由习知技艺者所知悉且并非本申请着重之处，因此不再多作说明。第一基板21背对液晶层25之一侧还设有一偏光层P1，并且第一基板21面向液晶层25之一侧还设有一共同电极层28，并且第一垂直配向层22设置于共同电极层28上并面向液晶层25。
第二基板23例如包括一玻璃基板以及一薄膜晶体管矩阵，由于这些构件可由习知技艺者所知悉且并非本申请着重之处，因此不再多作说明。第二基板22背对液晶层25之一侧还设有一偏光层P2，并且第二基板23面向液晶层25之一侧还设有一画素电极层29，并且第二垂直配向层24设置于画素电极层29上并面向液晶层25。
通过两偏光层P1、P2以及画素电极层29与共同电极层28之间电场的作用，可使各画素对应的液晶分子偏转并对应显示色光而形成影像。需说明的是，虽然图1的共同电极层28与画素电极层29是以一层表示，但习知技艺者了解共同电极层28与画素电极层29可为图案化电极层。另外，第一基板21与第二基板23还可包括其它构件，例如绝缘层、储存电容的电极、平坦化层等等，习知技艺者可视应用需求而增设。
本实施例的液晶显示装置2还包括第一配向控制结构26以及第二配向控制结构27。图2为本实施例之液晶显示装置2的侧视示意图，其显示液晶分 子通过第一配向控制结构26以及第二配向控制结构27的倾倒情形。为清楚说明，图2仅绘示基板、配向控制结构与液晶分子。如图2所示，第一配向控制结构26设置于第一基板21上且朝向所述液晶层25设置，第二配向控制结构27设置于第二基板23上且朝向液晶层25设置。本实施例的配向控制结构以凸体为例，但其也可以是孔隙、或是凸体与孔隙的组合。
如图2所示，液晶分子251由于与第一配向控制结构26及第二配向控制结构27形成相互垂直的关系，以致在第一配向控制结构26及第二配向控制结构27附近的液晶分子251与第一基板21(或第二基板23)的垂直方向呈一夹角。在未施加电场时，在第一配向控制结构26及第二配向控制结构27之间的液晶分子251是与第一基板21(或第二基板23)的垂直方向平行，而在施加电场时，液晶分子251由于受到预倾的液晶分子影响而决定了它们的倾倒方向，如此就使单一画素分成多个区域，并且也可加速液晶分子的反应速率。
图3为本申请一实施例的液晶显示装置2的单一画素P的示意图。如图3所示，单一画素P是由相邻数据线DL与相邻扫描线SL所定义，并且包括薄膜晶体管TFT与画素电极层29的画素电极部291，其中扫描线SL连接薄膜晶体管TFT的栅极，数据线DL连接薄膜晶体管TFT的源极，而薄膜晶体管TFT的漏极连接画素电极部291。由于画素的驱动方法可由习知技艺者所知悉且并非本申请的着重处，因此不再多作说明。
如图3所示，本实施例的第一配向控制结构26例如横设于画素电极部291中间，并与扫描线SL平行。本实施例的第二配向控制结构27例如与相邻扫描线SL重迭设置。第一配向控制结构26与第二配向控制结构27是以线形为例，但在其它实施例中可例如为弯曲形或其它形状。在本实施例的单一画素P中，是以一个第一配向控制结构26与两个第二配向控制结构27为例，但在其它实施例中可以其它数量来配置，例如二个第一配向控制结构26与二个第二配向控制结构27。
图4为本申请另一实施例的第一配向控制结构26与第二配向控制结构27的示意图，其是以第一基板21(或第二基板23)的垂直方向来看。在本实施例中，第一配向控制结构26与第二配向控制结构27是交替设置，且呈弯曲形。第一配向控制结构26与第二配向控制结构27相互平行。藉由此设置， 液晶分子251a、251b相对液晶分子251c、251d旋转90度。如此，同一画素就会产生至少四个不同液晶配向的区域，藉此可进一步达到广视角的效果。需说明的是，图4所示的第一配向控制结构26与第二配向控制结构27的数量可应用于单一画素或多个画素。通过第一配向控制结构26与第二配向控制结构27的交替、弯曲设计，可使液晶分子得到多面的预倾效果。
本实施例的配向控制结构可以是凸体、或孔隙、或凸体与孔隙的组合，以下以图5及图6来例示说明。
图5为本申请一实施例的第二配向控制结构27(或第一配向控制结构26)的示意图，其中第二配向控制结构27以凸体为例。第二基板23上设有画素电极层29，第二配向控制结构27设置于画素电极层29上，而第二垂直配向层24设置于画素电极层29与第二配向控制结构27上。
图6为本申请一实施例的第一配向控制结构26(或第二配向控制结构27)的示意图，其中第一配向控制结构26以孔隙为例。第一基板21上设有共同电极层28，且共同电极层28被图案化而形成孔隙结构，孔隙结构作为第一配向控制结构26。第一垂直配向层22设置于共同电极层28与孔隙结构上。
图7至图9为本申请一实施例的第一配向控制结构26与第二配向控制结构27的示意图，其是以第一基板21的垂直方向来看。
如图7所示，其中实线代表第一配向控制结构26。虚线代表第二配向控制结构27。第一配向控制结构26包括多个六角单元261，第二配向控制结构27包括多个六角单元271。在同一画素内的第一配向控制结构26的六角单元261或第二配向控制结构27的六角单元271彼此至少一部分相连(至少一部分不相连)，在本实施例中是以彼此相连为例作说明，而不相连例如指存在相邻的六角单元271的相邻二边存在一间隔。如图7所示，以第一基板21的垂直方向来看，本实施例的第一配向控制结构26的六角单元261是与第二配向控制结构27的六角单元271完全重迭，也就是第一配向控制结构26的六角单元261与第二配向控制结构27的六角单元271为等位设置。在其它的实施例中，第一配向控制结构26的六角单元261与第二配向控制结构27的六角单元271可为部分重迭或至少部分不重迭。
另外，六角单元261与271可不等位设置，以下以图8及图9举例说明。
如图8所示，以第一基板21的垂直方向来看，同一画素内的第一配向控 制结构26的六角单元261与第二配向控制结构27的六角单元271在左右方上相差一个相位而错位排列。在本实施例中，一个相位等同六角单元261或271的一个边长。
如图9所示，以第一基板21的垂直方向来看，同一画素内的第一配向控制结构26的六角单元261与第二配向控制结构27的六角单元271在上下方向上相差二分之一个相位而错位排列。
在其它实施例中，可视需求而使六角单元261与271在不同方向上以不同值的相位差而错位排列。
另外，对同一个六角单元261或271来说，可以是部分为凸体结构而另一部分为孔隙结构。
本实施例的液晶显示装置利用同时在上下基板设置对齐或错位的六角单元(六边形结构或蜂巢状)的配向控制结构，可以控制液晶分子在通电时的倾倒方向，以降低出现不同穿透率的区域，并降低这些区域的边界移动情况，以改善屏幕亮度与达到更快的反应时间。
图10为本申请另一实施例的第一配向控制结构26与第二配向控制结构27的示意图，其是以第一基板21的垂直方向来看。
如图10所示，其中实线代表第一配向控制结构26，虚线代表第二配向控制结构27。第一配向控制结构26包括多个第一几何单元262，第二配向控制结构27包括多个第二几何单元272。本实施例是以第一几何单元262为六角形(或蜂巢状)，第二几何单元272为三角形为例，但在其它实施例中，第一几何单元262与第二几何单元272可分别为不同的形状。在同一画素内的第一配向控制结构26的第一几何单元262或第二配向控制结构27的第二几何单元272彼此至少一部分相连(至少一部分不相连)，在本实施例中是以彼此相连为例作说明，而不相连例如指存在相邻的第一几何单元262的相邻二边存在一间隔。
如图10所示，以第一基板21的垂直方向来看，本实施例的第一配向控制结构26的第一几何单元262是与第二配向控制结构27的第二几何单元272完全重迭，这里定义这样的重迭等同于第一几何单元262与第二几何单元272为等位设置。在其它的实施例中，第一几何单元262与第二几何单元272可为部分重迭或至少部分不重迭。例如，同一画素内的第一几何单元262与第 二几何单元272在左右方向上相差一个相位或在上下方向上相差半个相位而错位排列，一个相位例如定义为第一几何单元262或第二几何单元272的一个边长。在其它实施例中，可视需求而使第一几何单元262与第二几何单元272在不同方向上以不同值的相位差而错位排列。另外，对同一个第一几何单元262或第二几何单元272来说，可以是部分为凸体结构而另一部分为孔隙结构。
图11为图10的第一几何单元262与第二几何单元272具有的几何特征的示意图。如图11所示，在本实施例中，第一几何单元262为六角形，第二几何单元272为三角形，并且第一几何单元262与第二几何单元272的外接圆为同心，或是具有相同的外接圆。
本实施例的液晶显示装置利用同时在上下基板设置对齐或错位的第一几何单元与第二几何单元的配向控制结构，且第一几何单元不同于第二几何单元，可以控制液晶分子在通电时的倾倒方向，以降低出现不同穿透率的区域，并降低这些区域的边界移动情况，以改善屏幕亮度与达到更快的反应时间。
图12至图14为本申请又一实施例的第一配向控制结构26与第二配向控制结构27的示意图，其是以第一基板21的垂直方向来看。
如图12所示，其中实线代表第一配向控制结构26。虚线代表第二配向控制结构27。第一配向控制结构26包括多个第一波形单元263，第二配向控制结构27包括多个第二波形单元273。在本实施例中，第一波形单元263为正弦波形，第二波形单元273为余弦波形，但在其它实施例中，第一波形单元263与第二波形单元273可为其它波形。另外，正弦波形结构与余弦波形结构的交错或交叉处是间隔201(或断点)。在本实施例中，以第一基板21的垂直方向来看，其中一第一波形单元263与对应的第二波形单元273形成一列，并且同一画素内的同一列的第一波形单元263与第二波形单元273为等位设置，相邻列的第一波形单元263为等位设置。
另外，在其它实施例中，同一列的第一波形单元263与第二波形单元273可错位设置，并且相邻列的第一波形单元263(或第二波形单元273)也可错位设置。
如图13所示，以第一基板21的垂直方向来看，同一画素内的同一列的第一波形单元263与第二波形单元273为等位设置，相邻列的第一波形单元 263为具有四分之一个相位差而错位设置。
如图14所示，以第一基板21的垂直方向来看，同一画素内的同一列的第一波形单元263与第二波形单元273为等位设置，相邻列的第一波形单元263为具有二分之一个相位差而错位设置。
在其它实施例中，可视需求而使第一波形单元263与第二波形单元273以不同值的相位差而错位排列。
另外，对同一个第一波形单元263或第二波形单元273来说，其可以是部分为凸体结构而另一部分为孔隙结构。
本实施例液晶显示装置则利用同时在上下基板设置对齐或错位的第一波形单元与第二波形单元的配向控制结构，且第一波形单元与第二波形单元彼此不相同，可以控制液晶分子在通电时的倾倒方向，以降低出现不同穿透率的区域，并降低这些区域的边界移动情况，以改善屏幕亮度与达到更快的反应时间。
以上内容是结合具体的实施方式对本申请所作的进一步详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本申请的保护范围。
