Description

液晶显示面板 技术领域
本发明涉及显示技术领域，尤其涉及一种液晶显示面板。
 背景技术
薄膜晶体管（Thin Film Transistor，TFT）是目前液晶显示装置（Liquid Crystal Display，LCD）和有源矩阵驱动式有机电致发光显示装置（Active Matrix Organic Light-Emitting Diode，AMOLED）中的主要驱动元件，直接关系平板显示装置的显示性能。
现有市场上的液晶显示器大部分为背光型液晶显示器，其包括液晶显示面板及背光模组（backlight module）。液晶显示面板的工作原理是在薄膜晶体管阵列基板（Thin Film Transistor Array Substrate，TFT Array Substrate）与彩色滤光片（Color Filter，CF）基板之间灌入液晶分子，并在两片基板上分别施加像素电压和公共电压，通过像素电压和公共电压之间形成的电场控制液晶分子的旋转方向，以将背光模组的光线透射出来产生画面。液晶显示面板成型工艺一般包括：前段阵列(Array)制程(薄膜、黄光、刻蚀及剥膜)、中段成盒(Cell)制程(TFT基板与CF基板贴合)及后段模组组装制程(驱动IC与印刷电路板压合)。其中，前段Array制程主要是形成TFT基板，以便于控制液晶分子的运动；中段Cell制程主要是在TFT基板与CF基板之间添加液晶；后段模组组装制程主要是驱动IC压合与印刷电路板的整合，进而驱动液晶分子转动，显示图像。
就目前主流市场上的TFT-LCD显示面板而言，可分为三种类型，分别是扭曲向列（Twisted Nematic，TN）或超扭曲向列（Super Twisted Nematic，STN）型，平面转换（In-Plane Switching，IPS）型、及垂直配向（Vertical Alignment，VA）型。其中VA型液晶显示面板相对其它种类的液晶显示面板具有极高的对比度，在大尺寸显示，如液晶电视等方面大量使用。
传统的VA型液晶显示面板包括：上基板、与上基板相对设置的下基板、夹于上基板和下基板之间的液晶层、设于下基板上的像素电极、及设于上基板上与像素电极相对的公共电极。为了使液晶能快速响应电场而倾倒，会对像素电极进行一些处理，如采用制造突起物，或者让PI膜表面液晶形成预倾角。另外，为了使VA型液晶显示面板获得更好的广视角特性，改善色偏问题，通常会将一个子像素划分成多个区域，并使每个区域中的液晶在施加电压后倒伏向不同的方向，从而使各个方向看到的效果趋于平均，一致。例如，一个子像素被“米字形”像素电极70划分成了四个畴，所述“米字形”像素电极70包括“十字形”主干701、及相对于水平方向自该“十字形”主干701分别向45°、135°、-135°、及-45°方向延伸的多个条状像素电极分支702，每两条同向相邻的两条状像素电极分支702之间形成一狭缝，即每个条状像素电极分支702与“十字形”主干701均呈45°，但实际中每个条状像素电极分支702与“十字形”主干701之间的夹角角度存在非45°，因此会损失一部分穿透率，影响显示效果。
 技术问题
本发明的目的在于提供一种液晶显示面板，可以使像素电极与公共电极之间的电场线产生弯曲，从而在对液晶层配向时，使液晶层的液晶快速倾倒形成预倾角，还能提升像素电极的穿透率。

位于所述第一主区域的色阻层的厚度和位于所述第二主区域的色阻层的厚度均最高，且位于所述4个次区域的色阻层的厚度均从靠近所述第一主区域和第二主区域向远离第一主区域和第二主区域的方向逐渐减小。
所述TFT层包括设于所述第二衬底基板上的栅极、覆盖所述第二衬底基板及栅极的栅极绝缘层、设于所述栅极绝缘层上的有源层以及设于所述有源层上并分别与有源层两端接触的源极和漏极。

所述像素电极通过一贯穿所述钝化层及色阻层的过孔与漏极接触。
 有益效果
本发明的有益效果：本发明的液晶显示面板包括相对设置的上基板和下基板以及设于所述上基板和下基板之间的液晶层；所述上基板包括第一衬底基板以及设于所述第一衬底基板上的公共电极；所述下基板包括第二衬底基板、设于所述第二衬底基板上的TFT层、设于所述TFT层上的材料层以及设于所述材料层上的像素电极；所述材料层沿垂直所述第二衬底基板的方向倾斜一预设的角度以使像素电极沿垂直所述第二衬底基板的方向倾斜一预设的角度，可以使像素电极与公共电极之间的电场线产生弯曲，从而在对液晶层配向时，使液晶层的液晶快速倾倒形成预倾角，还能提升像素电极的穿透率。
 附图说明
为了能更进一步了解本发明的特征以及技术内容，请参阅以下有关本发明的详细说明与附图，然而附图仅提供参考与说明用，并非用来对本发明加以限制。
附图中，
图1为现有的液晶显示面板的像素电极的结构示意图；

图3为本发明的液晶显示面板另一实施例的结构示意图；
图4为本发明的液晶显示面板的材料层的厚度减小方向的示意图。
 本发明的实施方式
为更进一步阐述本发明所采取的技术手段及其效果，以下结合本发明的优选实施例及其附图进行详细描述。
请参阅图1至图4，本发明提供一种液晶显示面板，包括：相对设置的上基板10和下基板20以及设于所述上基板10和下基板20之间的液晶层30；
所述上基板10包括第一衬底基板11以及设于所述第一衬底基板11上的公共电极12；

需要说明的是，本发明将材料层23沿垂直所述第二衬底基板21的方向倾斜一预设的角度以使像素电极24沿垂直所述第二衬底基板21的方向倾斜一预设的角度，那么可以使像素电极24与公共电极12之间的电场线产生弯曲，从而在对液晶层30配向时，使液晶层30的液晶快速倾倒形成预倾角。
具体的，所述像素电极24为整面覆盖在材料层23上的电极薄膜，由于本申请的像素电极24是倾斜的，像素电极24与公共电极12之间的电场线是弯曲的，因此不需要如同现有技术将像素电极做成“米字形”，弯曲的电场线的作用等同于“米字形”像素电极的作用，可以提升像素电极24的穿透率。
具体的，所述预设的角度为30°-60°。
具体的，请参阅图4，所述材料层23包括第一主区域231和第二主区域232，所述第一主区域231和第二主区域232垂直相交将所述材料层23分隔为4个次区域233；所述位于所述第一主区域231的材料层23的厚度和位于所述第二主区域232的材料层23的厚度均最高，且位于所述4个次区域233的材料层23的厚度均从靠近所述第一主区域231和第二主区域232向远离第一主区域231和第二主区域232的方向逐渐减小。也就是说本发明的材料层23的第一主区域231和第二主区域232相当于现有技术中的“米字形”像素电极的“十字形”的主干，4个次区域对应子像素的四个畴。
具体的，位于所述4个次区域233的材料层23的厚度逐渐减小的方向分别沿与水平方向呈45°、135°、-135°、及-45°夹角。
具体的，可以利用光罩的透光率的差异，使材料层223形成整面的倾斜结构。
具体的，请参阅图2，所述材料层23包括钝化层25即所述TFT阵列基板为传统的TFT阵列基板。位于所述第一主区域231的钝化层25的厚度和位于所述第二主区域232的钝化层25的厚度均最高，且位于所述4个次区域233的钝化层25的厚度均从靠近所述第一主区域231和第二主区域232向远离第一主区域231和第二主区域232的方向逐渐减小。
具体的，请参阅图3，所述材料层23包括色阻层26及设于所述色阻层26上的钝化层25，即所述TFT阵列基板为COA（Color filter OnArray，彩色滤光片整合于阵列基板）型TFT阵列基板。位于所述第一主区域231的色阻层26的厚度和位于所述第二主区域232的色阻层26的厚度均最高，且位于所述4个次区域233的色阻层26的厚度均从靠近所述第一主区域231和第二主区域232向远离第一主区域231和第二主区域232的方向逐渐减小。
具体的，所述TFT层22包括设于所述第二衬底基板21上的栅极221、覆盖所述第二衬底基板21及栅极221的栅极绝缘层222、设于所述栅极绝缘层222上的有源层223以及设于所述有源层223上并分别与有源层223两端接触的源极224和漏极225。
当所述材料层23包括钝化层25时，所述像素电极24通过一贯穿所述钝化层25的过孔251与漏极225接触。
当所述材料层23包括色阻层26及设于所述色阻层26上的钝化层25时，所述像素电极24通过一贯穿所述钝化层25的过孔251与漏极225接触。
具体的，所述钝化层25的材料为PFA（聚四氟乙烯）。
综上所述，本发明的液晶显示面板包括相对设置的上基板和下基板以及设于所述上基板和下基板之间的液晶层；所述上基板包括第一衬底基板以及设于所述第一衬底基板上的公共电极；所述下基板包括第二衬底基板、设于所述第二衬底基板上的TFT层、设于所述TFT层上的材料层以及设于所述材料层上的像素电极；所述材料层沿垂直所述第二衬底基板的方向倾斜一预设的角度以使像素电极沿垂直所述第二衬底基板的方向倾斜一预设的角度，可以使像素电极与公共电极之间的电场线产生弯曲，从而在对液晶层配向时，使液晶层的液晶快速倾倒形成预倾角，还能提升像素电极的穿透率。
以上所述，对于本领域的普通技术人员来说，可以根据本发明的技术方案和技术构思作出其他各种相应的改变和变形，而所有这些改变和变形都应属于本发明权利要求的保护范围。
