Description

液晶显示面板
技术领域
本发明涉及显示领域，尤其涉及一种液晶显示面板。
背景技术
液晶显示面板(Liquid Crystal Display,LCD)主要包括薄膜晶体管(Tin FilmTransistor,TFT)阵列基板、彩色滤光(Color Filter,CF)基板、设置在所述TFT阵列基板及所述CF基板之间且有一定排列方向的液晶层以及形成在TFT阵列基板和CF基板内侧用于分配液晶分子的配向层(Alignment layer)。为了保持液晶显示面板具有均一的盒厚高度(cell gap)，通常在液晶层内部设置一定数量的光学间隙子(Photo Spacer,PS)。
具体地，光学间隙子设置在所述薄膜晶体管阵列基板及所述彩色滤光基板之间，以支撑所述薄膜晶体管阵列基板及所述彩色滤光基板，进而保持液晶显示面板具有均一的盒厚高度。在薄化、抛光、盖板玻璃贴合、运送等制造程序或任何产品可靠度试验当中会发生TFT阵列光学间隙子基板和光学间隙子CF基板的暂时性相对位移，此相对位移会使光学间隙子刮伤TFT阵列基板或者CF基板上的配向层。配向层刮伤后失去液晶配向能力，造成显示屏幕画面出现斑点，造成液晶显示面板品质下降，影响生产良率。
发明内容
针对现有技术中的液晶显示面板存在的上述缺陷，本发明提供一种液晶显示面板，可以有效减少因光学间隙子相对位移而产生的刮伤，可以有效消除因此而产生的屏幕画质降低现象，同时提高了液晶显示面板的生产良率。
一种液晶显示面板，其包括薄膜晶体管阵列基板、液晶层以及光学间隙子，所述光学间隙子位于液晶层中，所述薄膜晶体管阵列基板包括像素电极层及配向层，所述配向层设置于所述薄膜晶体管阵列基板与所述液晶层相邻的一侧，所述像素电极层设置于所述配向层远离所述液晶层一侧，所述配向层包括接触部，所述光学间隙子的底端与所述接触部抵持，所述薄膜晶体管阵列基板还包括与所述接触部相邻的阻挡部，阻挡部为相对于所述接触部朝向彩色滤光基板形成的凸起，以限制光学间隙子在薄膜晶体管阵列基板上的相对位移。
一种液晶显示面板，其包括薄膜晶体管阵列基板、液晶层以及光学间隙子，所述光学间隙子位于液晶层中，所述薄膜晶体管阵列基板包括平坦层，所述薄膜晶体管阵列基板还包括阻挡部，所述阻挡部为所述平坦层靠近所述液晶层一侧形成的可容纳所述光学间隙子至少部分的凹陷区域，所述光学间隙子的底端嵌入所述阻挡部之中。
相比于现有技术，本发明的液晶显示面板的薄膜晶体管阵列基板上设置有阻挡部，所述阻挡部为形成于所述光学间隙子两侧的凸起，或为容置所述光学间隙子底端的凹陷区域，这些结构可以有效限制光学间隙子相对于薄膜晶体管阵列基板发生位移，从而有效避免配向膜被光学间隙子刮伤，且阻挡部可以是与薄膜晶体管阵列基板中的电极电性连接的金属块，该金属块还可以兼具其他的电性功能；另一方面，彩色滤光基板上的黑矩阵分布与光学间隙子所在位置相对设置，从而有效遮蔽小范围损伤而产生的漏光，提高液晶显示面板的品质及良率。

具体实施方式
为了使本申请所揭示的技术内容更加详尽与完备，可以参照附图以及本发明的下述各种具体实施例，附图中相同的标记代表相同或者相似的组件。然而，本领域的普通技术人员应当理解，下文中所提供的实施例并非用来限制本发明所覆盖的范围。此外，附图仅仅用于示意性地加以说明，并未依照其原尺寸进行绘制。
本发明的液晶显示面板的薄膜晶体管阵列基板上设置有阻挡部或阻挡部，这些结构可以有效限制光学间隙子相对于薄膜晶体管阵列基板发生相对位移，从而有效避免配向膜被光学间隙子刮伤，且阻挡部可以是与薄膜晶体管阵列基板中的像素电极电性连接的金属块，该金属块还可以兼具其他的电性功能；另一方面，彩色滤光基板上的黑矩阵分布与光学间隙子所在位置相对设置，从而有效遮蔽小范围损伤而产生的漏光，提高液晶显示面板的品质及良率。
下面参照附图，对本发明的具体实施方式作进一步的详细描述。
第一实施例
如图1、图2及图3所示一种液晶显示面板20，图1为液晶显示面板20的局部俯视示意图，图2为图1沿II-II方向的剖视示意图，图3为图1沿III-III方向的剖视示意图。
所述液晶显示面板20包括彩色滤光基板21、与彩色滤光基板21相对且间隔设置的薄膜晶体管阵列基板25、位于彩色滤光基板21与薄膜晶体管阵列基板25之间的液晶层23以及位于液晶层23中的多个光学间隙子231。
所述彩色滤光基板21包括黑矩阵211、彩色滤光单元213以及防护层215。虽然图未示出，但是彩色滤光基板21还可包括用于承载所述黑矩阵211、彩色滤光单元213的上基板。
所述薄膜晶体管阵列基板25包括配向层251、像素电极层253、平坦层255以及导通孔254。当然，虽然图未示出，但是薄膜晶体管阵列基板25还包括下基板，以及形成于下基板上的薄膜晶体管阵列。
所述液晶层23填充于所述彩色滤光基板21与薄膜晶体管阵列基板25之间。
所述防护层215设置于彩色滤光基板21靠近液晶层23一侧，所述防护层215具备液晶配向功能，其可以由摩擦配向、光配向或其他任一种可行的配向工艺制得。所述彩色滤光单元213以及所述黑矩阵211设置于防护层215远离液晶层23一侧，所述彩色滤光单元213包括三种彩色滤光子单元，即红色(R)滤光子单元、绿色(G)滤光子单元以及蓝色(B)滤光子单元。所述彩色滤光单元213与所述黑矩阵211同层设置，黑矩阵211将彩色滤光单元213的各滤光子单元隔开，使所述彩色滤光单元213的红色滤光子单元、绿色滤光子单元、蓝色滤光子单元间隔设置。所述黑矩阵211为不透光材质，其具有遮蔽光线的作用；所述彩色滤光单元213为透光材质，其仅允许相应颜色的光通过，从而改变光线颜色。
所述光学间隙子231固设于所述彩色滤光基板21之上光学间隙子231有支撑作用，用于保持一定的液晶盒间隙。所述光学间隙子231一端与所述防护层215接触，该端部称之为顶端2311，另一端抵持薄膜晶体管阵列基板25，该端部称之为底端2315。本实施例中，所述顶端2311的尺寸大于底端2315的尺寸。每个光学间隙子231均对应于所述彩色滤光基板21的黑矩阵211设置，即，每个光学间隙子231在彩色滤光基板21上的投影均与黑矩阵211重叠(不超出黑矩阵211的范围)。因所述黑矩阵211具有不透光性，光学间隙子231对应黑矩阵211设置，一方面可以避免所述光学间隙子231对液晶显示面板20透光性的影响，另一方面可以遮蔽因配向层251受光学间隙子231的底端2315摩擦受损而产生的漏光。本实施例中，对应所述光学间隙子231设置的黑矩阵211在所述薄膜晶体管阵列基板25上的投影面积大于所述光学间隙子231在所述薄膜晶体管阵列基板25上的投影面积。
所述配向层251设置于薄膜晶体管阵列基板25靠近液晶层23的一侧，平坦层255设置于薄膜晶体管阵列基板25远离液晶层23的一侧。所述像素电极层253设置于配向层251及平坦层255之间。像素电极层253及配向层251均沿平坦层255表面设置。配向层251包括多个接触部，所述像素电极层253并未设置于所述接触部256对应的区域。所述光学间隙子231的底端2315抵持于配向层251的接触部256。
如图1和图3所示，所述薄膜晶体管阵列基板25还包括阻挡部252，所述阻挡部252紧邻所述接触部256设置，用于限制光学间隙子231在薄膜晶体管阵列基板25上的相对位移。本实施例中，阻挡部252为相对于接触部256朝向彩色滤光基板21形成的凸起，具体地，通过在所述像素电极层253与所述配向层251之间埋设具有一定厚度的块状或者条状的隔垫物2523以使对应部位的配向层251朝向彩色滤光基板21凸起，从而形成所述阻挡部252。所述隔垫物2523的材料可以为金属，具体的可以是金属复合物，如钛铝钛；所述隔垫物2523的材料也可以为无机物或有机物等其他符合要求的导电材料，如石墨或掺杂有导电颗粒的聚合物。所述隔垫物2523位于所述配向层251和所述像素电极层253之间并与所述像素电极层253电性连接。所述阻挡部252高出其周围区域。
对应于薄膜晶体管阵列基板25上的多个光学间隙子231，所述薄膜晶体管阵列基板25上存在多组所述阻挡部252。本实施例中，所述阻挡部252包括第一阻挡部2521和第二阻挡部2522，所述每个接触部256沿第一方向(如图1中III-III方向)两侧分别分布有一个第一阻挡部2521和一个第二阻挡部2522，且所述第一阻挡部2521和第二阻挡部2522均不与导通孔接触。本实施例中，所述第一阻挡部2521为岛状，各第一阻挡部2521相互之间不接触。所述第二阻挡部2522为条状，沿第二方向延伸且在同一条直线上的各相邻的第二阻挡部2522可以相互连接形成一连续的条状。所述第二方向大致垂直于第一方向。
在其它实施例中，第一阻挡部2521和第二阻挡部2522均为岛状，或者均为条状。
所述导通孔254形成于所述平坦层255上，所述每个接触部256沿第二方向(如图1中II-II方向)两侧各分布有一个导通孔254，所述导通孔254是现有技术的薄膜晶体管阵列基板25中常见的一种结构，本实施例中，导通孔254用于像素电极层253的各像素电极与薄膜晶体管阵列基板25上的薄膜晶体管的栅极(图未示)实现电连接。
所述阻挡部252高出其周围区域，因此，所述阻挡部252可以有效限制光学间隙子231相对于薄膜晶体管阵列基板25发生相对位移，可以有效避免因位移剐蹭对配向层251造成损伤而引起的漏光，可以有效提高面板显示效果；同时，所述隔垫物2523与所述像素电极层253电性连接，所述隔垫物2523本身可以是导电材料，所述隔垫物2523还可以作为电极使用，比如作为内嵌式触控感测电极和公共电极，从而进一步简化面板结构。
第二实施例
如图4及图5所示为本发明第二实施例的液晶显示面板50，图4为液晶显示面板50的局部俯视示意图，图5为图4沿V-V方向的剖视示意图。
所述液晶显示面板50包括彩色滤光基板51、与彩色滤光基板51相对且间隔设置的薄膜晶体管阵列基板55、位于彩色滤光基板21与薄膜晶体管阵列基板25之间的液晶层53以及位于液晶层53中的多个光学间隙子531。
所述彩色滤光基板51包括黑矩阵511、彩色滤光单元513以及防护层515。虽然图未示出，但是彩色滤光基板51还可包括用于承载所述黑矩阵511、彩色滤光单元513的上基板。
所述薄膜晶体管阵列基板55包括配向层551、像素电极层553、平坦层555以及导通孔554。当然，虽然图未示出，但是薄膜晶体管阵列基板55还包括下基板，以及形成于下基板上的薄膜晶体管阵列。
所述液晶层53填充于所述彩色滤光基板51与薄膜晶体管阵列基板55之间。
所述防护层515设置于彩色滤光基板51靠近液晶层53一侧，所述防护层515具备液晶配向功能，其可以由摩擦配向、光配向或其他任一种可行的配向工艺制得。所述彩色滤光单元513以及所述黑矩阵511设置于防护层515远离液晶层53一侧，所述彩色滤光单元513包括三种彩色滤光子单元，即红色(R)滤光子单元、绿色(G)滤光子单元以及蓝色(B)滤光子单元。所述彩色滤光单元513与所述黑矩阵511同层设置，黑矩阵511将彩色滤光单元513的各滤光子单元隔开，使所述彩色滤光单元513的红色滤光子单元、绿色滤光子单元、蓝色滤光子单元间隔设置。所述黑矩阵511为不透光材质，其具有遮蔽光线的作用；所述彩色滤光单元513为透光材质，其仅允许相应颜色的光通过，从而改变光线颜色。
所述光学间隙子531固设于所述彩色滤光基板51之上，光学间隙子531有支撑作用，用于保持一定的液晶盒间隙。所述光学间隙子531一端与所述防护层515接触，该端部称之为顶端5311，另一端抵持薄膜晶体管阵列基板55，该端部称之为底端5315。本实施例中，所述顶端5311的尺寸大于底端5315的尺寸。每个光学间隙子531均对应于所述彩色滤光基板51的黑矩阵511设置，即，每个光学间隙子531在彩色滤光基板51上投影均与黑矩阵511重叠(不超出黑矩阵511的范围)。因所述黑矩阵511具有不透光性，光学间隙子531对应黑矩阵511设置，一方面可以避免所述光学间隙子531对液晶显示面板50透光性的影响，另一方面可以遮蔽因配向层551受光学间隙子531的底端5315摩擦受损而产生的漏光。本实施例中，对应所述光学间隙子531设置的黑矩阵511在所述薄膜晶体管阵列基板55上的投影面积大于所述光学间隙子531在所述薄膜晶体管阵列基板55上的投影面积。
所述配向层551设置于薄膜晶体管阵列基板55靠近液晶层53的一侧，平坦层555设置于薄膜晶体管阵列基板55远离液晶层53的一侧。所述像素电极层553置于配向层551及平坦层555之间。像素电极层553及配向层551均沿平坦层555表面设置。
如图4和图5所示，所述薄膜晶体管阵列基板55还包括阻挡部552，在本实施例中，在所述平坦层555靠近所述液晶层53一侧形成一可容纳所述光学间隙子531至少部分的凹陷区域，该凹陷区域即为阻挡部552，所述光学间隙子531远离彩色滤光基板51的底端5315嵌入所述阻挡部552之中。所述像素电极层553并未设置于所阻挡部552对应的区域，所述配向层551延伸至形成该阻挡部552的凹陷区域内。
所述导通孔554形成于所述平坦层555上，所述每个阻挡部552沿第二方向两侧分布有一个导通孔554，所述导通孔554是现有技术的薄膜晶体管阵列基板55中常见的一种结构，本实施例中，导通孔554用于像素电极层553的各像素电极与薄膜晶体管阵列基板55上的薄膜晶体管的栅极(图未示)实现电连接。
上述光学间隙子531一端恰好置于阻挡部552中，因此，上述阻挡部552可以有效限制光学间隙子531相对于薄膜晶体管阵列基板55发生位移，可以有效避免因光学间隙子531的位移剐蹭对配向层551造成损伤而引起的漏光，可以有效提高面板显示效果。
上文中，参照附图描述了本发明的具体实施方式。但是，本领域中的普通技术人员能够理解，在不偏离本发明的精神和范围的情况下，还可以对本发明的具体实施方式作各种变更和替换。这些变更和替换都落在本发明权利要求书所限定的范围内。
