Description
技术领域 technical field
本发明是有关于一种液晶显示面板及其制作方法,且特别是有关于一种应用聚合物稳定配向技术的液晶显示面板及其制作方法。The present invention relates to a liquid crystal display panel and a manufacturing method thereof, and in particular to a liquid crystal display panel using polymer stable alignment technology and a manufacturing method thereof.
背景技术 Background technique
目前,在液晶显示面板技术中,能够达成广视角要求的技术有扭转向列型(twist nematic,TN)液晶加上广视角膜(wide viewing film)、共平面切换型(in-plane switching,IPS)液晶显示面板、边际场切换型(fringe fieldswitching)液晶显示面板、多域垂直配向式(multi-domain verticallyalignment,MVA)液晶显示面板等方式。在这些技术中,多域垂直配向式液晶显示面板已为广泛应用在各种电子产品当中。At present, in liquid crystal display panel technology, the technologies that can meet the requirements of wide viewing angle include twist nematic (TN) liquid crystal plus wide viewing film (wide viewing film), in-plane switching (IPS) ) liquid crystal display panel, fringe field switching (fringe field switching) liquid crystal display panel, multi-domain vertical alignment (multi-domain vertically aligned, MVA) liquid crystal display panel, etc. Among these technologies, the multi-domain vertical alignment liquid crystal display panel has been widely used in various electronic products.
现有的多域垂直配向式液晶显示面板是利用配向结构(alignmentstructure)的配置以令不同区域内的液晶分子以不同角度倾倒,而达到广视角的功效。然而,多域垂直配向式液晶显示面板的设计仍有显示对比不佳的问题。因此,一种聚合物稳定配向(Polymer-stablized alignment,PSA)式液晶显示面板,其利用聚合物稳定配向制程以形成多领域配向的配向方式被提出。The existing multi-domain vertical alignment type liquid crystal display panel utilizes the configuration of the alignment structure to make the liquid crystal molecules in different regions tilt at different angles, so as to achieve the effect of wide viewing angle. However, the design of the multi-domain vertical alignment liquid crystal display panel still has the problem of poor display contrast. Therefore, a polymer-stablized alignment (PSA) type liquid crystal display panel, which uses a polymer-stabilized alignment process to form a multi-domain alignment alignment method, is proposed.
聚合物稳定配向制程须先将反应性单体掺杂于液晶层中,并施与液晶层特定的电场。在此电场下以一光线或热源照射液晶层,则反应性单体会聚合并固化,以于液晶层两侧的基板上同时形成聚合物稳定配向层(polymerstabilized alignment layer)。其中,聚合物稳定配向层的分子会呈现特定的结构,而有助于使液晶分子以不同的方向倾倒与排列,并达到广视角显示效果。The polymer stabilized alignment process requires doping reactive monomers into the liquid crystal layer and applying a specific electric field to the liquid crystal layer. When the liquid crystal layer is irradiated with a light or a heat source under the electric field, the reactive monomers will be polymerized and solidified to form polymer stabilized alignment layers on the substrates on both sides of the liquid crystal layer. Among them, the polymer stabilizes the molecules of the alignment layer to present a specific structure, which helps to make the liquid crystal molecules tilt and align in different directions, and achieve a wide viewing angle display effect.
此外,为了提高对液晶分子的配向效果,聚合物稳定配向式液晶显示面板还会在像素电极上形成微狭缝或是在基板上制作配向凸起。不过,像素电极上的微狭缝会造成像素显示亮度的损失而影响显示质量。另一方面,配向凸起的配置会使位于配向凸起周边的液晶分子的倾倒方向不连续,而造成漏光的情形。如此,液晶显示面板的显示对比会被降低,而额外制作配向凸起也会造成制程上的负担并影响制程的良率。In addition, in order to improve the alignment effect of liquid crystal molecules, the polymer stabilized alignment type liquid crystal display panel also forms micro slits on the pixel electrodes or makes alignment protrusions on the substrate. However, the micro slits on the pixel electrodes will cause the loss of pixel display brightness and affect the display quality. On the other hand, the disposition of the alignment protrusions will discontinuously tilt the direction of liquid crystal molecules located around the alignment protrusions, resulting in light leakage. In this way, the display contrast of the liquid crystal display panel will be reduced, and the extra fabrication of alignment bumps will also cause a burden on the manufacturing process and affect the yield of the manufacturing process.

The method of polymerizing the
本实施例的制作方式是在照光作用下,聚合液晶层150内的单体材料154,使其形成聚合物层在第一基板110与第二基板130的内侧表面。如此一来,便可以在第一基板110与液晶层150之间形成一第一聚合物稳定配向层162,并在第二基板130与液晶层150之间形成一第二聚合物稳定配向层164,其中图2B仅用以示意表示。然后,移除电场,以完成液晶显示面板100。The manufacturing method of this embodiment is to polymerize the
本实施例的第一基板110中,各像素电极118上方所配置的辅助电极120与各像素电极118分属不同的膜层且配置于不同的平面上。因此,像素电极118被通入第二固化电压Vcur2时,辅助电极120的边缘会产生边际电场效应。此外,围绕辅助电极120的遮蔽电极122也会在像素电极118边缘产生边际电场效应。因此,各像素区域P中,电场E的分布并非均匀一致的。In the
在辅助电极120与遮蔽电极122所提供的边际电场效应之下,液晶分子152将会随着特定的方式排列,例如是如图2B所绘示的状态。换言之,在第一基板100的结构设计下,像素电极118被通入第二固化电压Vcur2时,不同位置上的液晶分子152将会沿不同的预倾角度排列。此时,液晶分子152的排列方式会影响单体材料154的聚合过程。因此,第一聚合物稳定配向层162与第二聚合物稳定配向层164中的聚合物排列方式例如具有特定的结构特征。本发明直接施加第二固化电压Vcur2至像素电极118,甚至比利用共通电极耦合像素电极118的固化电压,更可提供稳定与准确的液晶配向效果。Under the effect of the fringe electric field provided by the
电场E被移除后,第一聚合物稳定配向层162与第二聚合物稳定配向层164的特定结构特征将可提供一定的配向锚定力而有助于提高液晶分子152的响应速率。也就是说,本实施例不需通过微狭缝或是微凸起的设计就可以进行聚合物稳定配向制程以形成多领域配向式的液晶显示面板100,并且提供更稳定的配向效果。因此,依照上述制程所制作出来的液晶显示面板100中,液晶分子152的响应速率良好,且液晶显示100的显示质量不会受到微狭缝或配向凸起的影响而可进一步被提升。After the electric field E is removed, the specific structural features of the first polymer stabilized alignment layer 162 and the second polymer stabilized
在本实施例中,像素电极118完整地配置于像素区域P中,所以液晶显示面板100在显示画面时整个像素区域P中的液晶分子都可以进行显示。相较于现有的微狭缝上方的液晶分子无法进行显示的设计而言,液晶显示面板100具有较佳的显示亮度。除此之外,为了使液晶显示面板100可呈现多彩化的显示效果,第一基板110或第二基板130可以还具有多个彩色滤光单元,其分别位于对应的像素区域P中。亦即,第二基板130可以是彩色滤光基板或是第一基板110可以是彩色滤光层制作于像素数组上(Color filter on Array,COA)或是像素数组制作于彩色滤光层上(Array on Color filter,AOC)的设计。In this embodiment, the
值得一提的是,本实施例的制作方法不被局限于应用在如图1所示的液晶显示面板100中。在其它的实施例中,上述的制作方法也可以应用在不具有辅助电极120与遮蔽电极122设计的液晶显示面板中。另外,由图2B可知,从金属膜层的迭置顺序来看,液晶显示面板100中,数据配线114是以直接配置于基板上的第一层金属层制作而成的,而扫描配线112是以配置于绝缘层上第二层金属层制作而成的。同时,辅助电极120与遮蔽电极122是以第三层金属层制作而成的。不过,本发明并不限于此。在其它的实施方式中,数据配线114与扫描配线112也可分别以第二层金属层以及第一层金属层加以制作。It is worth mentioning that the manufacturing method of this embodiment is not limited to be applied in the liquid
图3A与图3B分别为本发明的另一实施例的液晶显示面板的第一基板俯视示意图及局部剖面示意图,其中图3B所示为沿图3A的剖线D-D’与E-E’的剖面图。请同时参照图3A与图3B,第一基板300具有多条扫描配线310与多条数据配线320,其中图3A分别以两条为例。扫描配线310分别与数据配线320相交,而在第一基板300上划分出多个像素区域P。此外,每一像素区域P内的第一基板300还具有一主动组件330、一像素电极340、两辅助电极350以及一遮蔽电极360。上述各组件的耦接关系例如与先前实施例的第一基板110的各组件的耦接关系相同。此外,两个辅助电极350都被遮蔽电极360所围绕。3A and 3B are respectively a schematic top view and a partial cross-sectional view of the first substrate of a liquid crystal display panel according to another embodiment of the present invention, wherein FIG. 3B is shown along the section lines DD' and EE' in FIG. 3A sectional view. Please refer to FIG. 3A and FIG. 3B at the same time. The
第一基板300中,两个辅助电极350的设计应用于液晶显示面板时有助于使液晶显示面板中的液晶分子沿更多多配向领域排列。也就是说,第一基板300的设计可使液晶显示面板的广视角显示效果更为提升。此外,为了搭配两个辅助电极350的设计,本实施例的遮蔽电极360例如呈现”日”字型的设计。In the
具体而言,由图3B的剖面图来看,扫描配线310在本实施例中是以第一层金属层制作而成,数据配线320是以第二层金属层制作而成,且辅助电极350与遮蔽电极360同为第三层金属层制作而成。换言之,第一基板300的制程顺序与上述的第一基板110的制程顺序不同。Specifically, from the cross-sectional view of FIG. 3B , the
另外,第一基板300中,辅助电极350与像素电极340分属于不同的膜层并位于不同的平面上。所以,像素电极340被输入电压时,辅助电极350与像素电极340之间会产生边际电场效应。同样地,遮蔽电极360与像素电极340之间也会产生对应的边际电场效应。所以,第一基板300应用于前述实施例的液晶显示面板的制作方法时,有助于使液晶显示面板中的液晶层呈现多领域配向排列。也就是说,第一基板300应用在前述的制作方法时,有助于提升液晶显示面板的液晶分子的响应速率并提高液晶显示面板的显示质量。In addition, in the
综上所述,本发明将不同的固化电压分别输入扫描配线与数据配线,直接提供固化电压至像素电极,以对不具有微狭缝与配向凸起的液晶显示面板进行稳定聚合物配向制程。因此,本发明的液晶显示面板具有良好的显示亮度,而且液晶显示面板内的液晶分子也可维持相当优越的响应速率。整体而言,本发明的液晶显示面板的制作方法使液晶显示面板的质量更进一步地提升。To sum up, in the present invention, different curing voltages are respectively input into the scanning wiring and the data wiring, and the curing voltage is directly provided to the pixel electrodes, so as to stabilize the polymer alignment of the liquid crystal display panel without micro-slits and alignment protrusions.
