在一种实施例中，请参照图1所示，1示出了本申请实施例提供的液晶显示面板的一种剖面结构示意图。如图所示，本申请实施例提供的液晶显示面板包括第一基板100、第二基板200、以及填充于第一基板100和第二基板200之间的液晶层300，第二基板200包括位于液晶层300侧的支撑柱250，在支撑柱250对应的位置，第一基板100靠近液晶层300的表面设有滑动阻尼结构101。
本申请实施例提供了一种液晶显示面板，该液晶显示面板通过在第一基板靠近液晶层的表面设置滑动阻尼结构，增大了支撑柱在受到外部压力时沿第一基板表面发生滑移的阻力，减小了支撑柱侧滑的滑移量，缓解了支撑柱滑移损伤像素透光区内的配向层的风险，提高了液晶显示面板的抗按压能力及产品良率。
具体的，请参照图1，第一基板100为阵列基板，包括从下到上依次层叠设置的第一衬底110，第一阵列层120、有机层130、第二阵列层140和第一配向层150。
其中，第一衬底110通常为透明的刚性衬底，如透明玻璃。
第一阵列层120通常包括从下到上依次层叠设置的半导体有源层、第一绝缘层、第一栅极层、第二绝缘层、第二栅极层、第三绝缘层和源漏极层，其中，半导体有源层、第一栅极层、第二栅极层和源漏极层共同形成液晶显示面板的薄膜晶体管和电容等元器件。半导体有源层图案化形成薄膜晶体管的有源区，有源区又包括沟道区和位于沟道区两侧的掺杂区，半导体有源层的材料可以是氧化物半导体材料，也可以是多晶硅材料或单晶硅材料，在此不做限定；第一栅极层图案化形成薄膜晶体管的第一栅极和电容的第一电极板，第二栅极层图案化形成薄膜晶体管的第二栅极和电容的第二电极板，第一栅极和第二栅极同时对应于有源层的沟道区；源漏极层图案化形成薄膜晶体管的源极和漏极，源极和漏极分别通过贯穿第一绝缘层、第二绝缘层和第三绝缘层的过孔与沟道区两侧的掺杂区连接。薄膜晶体管和电容等元器件、以及阵列基板100中的信号线共同构成显示面板的驱动电路，用于驱动液晶层300中的液晶发生偏转。第一绝缘层设置于半导体有源层和第一栅极层之间，第二绝缘层设置于第一栅极层和第二栅极层之间，第三绝缘层设置于第二栅极层和源漏极层之间，第一绝缘层、第二绝缘层和第三绝缘层分别用于隔绝与其相邻的两导电层。在本申请实施例提供的液晶显示面板中，第一阵列层120也可以是本领域技术人员所熟知的其他结构，以上第一阵列层120的结构仅在于解释说明本申请实施例提供的显示面板的结构，不用于限定。
有机层130为平坦层，形成于源漏极层上，用于平坦化第一阵列层120，为有机层130上的第二阵列层140的制备提供平坦的基底。平坦层的材料主要包括丙烯酸系列有机材料和硅氧烷系列有机材料，具体包括但不限于亚克力、聚酰亚胺或苯并环丁烯等的有机材料。有机层130的厚度范围为2-3微米。
第二阵列层140，形成于有机层130上，通常为电极层。当液晶显示面板为扭曲向列型（Twisted Nematic，TN）液晶显示面板或垂直配向型（Vertical Alignment，VA）液晶显示面板时，第二阵列层140为第一电极层，第一电极层图案化形成间隔设置且相互独立的第一电极，第一电极通过贯穿平坦层130的过孔与下方薄膜晶体管的源极或漏极连接，从而与液晶显示面板的驱动电路进行连接；第二基板200包括对应于第一电极层的第二电极层。当液晶显示面板为面内转换型（In-Plane Switching，IPS）液晶显示面板时，第二阵列层140为一层电极层，该电极层包括同层设置的第一电极和第二电极，同样的，第一电极通过贯穿平坦层130的过孔与下方薄膜晶体管的源极或漏极连接，从而与液晶显示面板的驱动电路进行连接。当液晶显示面板为面内开关型（Fringe Field Switching，FFS）液晶显示面板时，第二阵列层140包括第一层电极层、第二电极层和位于第一电极层和第二电极层之间的绝缘层，同样的，第一电极层图案化形成间隔设置且相互独立的第一电极，第一电极通过贯穿平坦层130的过孔与下方薄膜晶体管的源极或漏极连接，从而与液晶显示面板的驱动电路进行连接。第二阵列层140的厚度通常控制在0.3微米左右。
第一配向层150，形成于第二阵列层140上，用于对液晶层300内的液晶分子进行配向，控制液晶分子的排列。第一配向层150的材料为有机高分子材料，通常为聚酰亚胺（Polyimide，PI）。第一配向层150的厚度范围通常为500-800埃米。
第二基板200为彩膜基板，包括从上到下依次层叠设置的第二衬底210、黑矩阵层220、彩膜层230、平坦层240、支撑柱250和第二配向层260。
其中，第二衬底210与第一衬底110相类似，通常为透明的刚性衬底，如透明玻璃。
黑矩阵层220，形成于第二基板下，图案化形成相互间隔的色阻开口，色阻开口对应于液晶显示面板的像素透光区PA，图案化后黑矩阵层220所在的位置对应于液晶显示面板的遮光区BA。黑矩阵层220的材料一般为参入黑色颜料的黑色树脂，用于遮挡相邻像素之间的光线，避免相连彩膜层混色，提高液晶显示面板的对比度，同时减少外界光线的反射，降低低蓝光效应，另外防止外界光线照射薄膜晶体管的沟道而增加漏电流。
彩膜层230，形成于黑矩阵层220下，包括同层设置的红色色阻层、蓝色色阻层和绿色色阻层，红色色阻层、蓝色色阻层和绿色色阻层分别覆盖不同的色阻开口，用于透过与其色阻层颜色相同的光，阻挡与其颜色不同的光线。色阻层的材料一般包括与其颜色相对应的颜料、光固化树脂、碱性可溶性树脂、光引发剂等材料。
平坦层240，形成于彩膜层230下，用于保护彩膜层230，同时实现第二基板200表面的平坦化。平坦层240的材料主要包括丙烯酸系列有机材料和硅氧烷系列有机材料，具体包括但不限于亚克力、聚酰亚胺或苯并环丁烯等的有机材料。
支撑柱250，形成于平坦层240下，且位于遮光区BA内，用于支撑第一基板100和第二基板200，保持液晶显示面板的盒厚均一性。支撑柱250的主要材料为丙烯树脂。通常情况下，支撑柱250的一端位于第二基板200上，另一端与第一基板100接触，即与第一基板100的第一配向层150接触。
第二配向层260，形成于平坦层240下，用于对液晶层300内的液晶分子进行配向，控制液晶分子的排列。第二配向层260的材料为有机高分子材料，通常为聚酰亚胺。第二配向层260和第一配向层150对液晶分子的配向方向交叉垂直。
在一种实施例中，如图1所示，滑动阻尼结构101形成于第一基板100靠近液晶层300的表面，滑动阻尼结构101位于遮光区BA内且对应于支撑柱250，进一步，滑动阻尼结构101的边缘可与遮光区BA的边缘不重合。滑动阻尼结构101在增加支撑柱250在第一基板100上的滑移阻力的同时，避免了滑动阻尼结构101对像素透光区PA内液晶分子配向的影响。另外，支撑柱250滑移量的减小，有助于减小黑矩阵层220对支撑柱250的遮光量，即黑矩阵层220的宽度范围可以进行相对应的缩小设置，色阻开口可以进行相应的扩大设置，从而有助于提高液晶显示面板的开口率和穿透率，降低液晶显示面板的背光成本。
在一种实施例中，如图1至4所示，滑动阻尼结构101为在第一基板100靠近支撑柱250的表面，支撑柱250受力滑动方向上设置的凹凸结构。在一种实施例中，如图1所示，该凹凸结构由第一基板100上的三个膜层结构构成，具体由有机层130、第二阵列层140和第一配向层150构成。具体的，在遮光区BA内，支撑柱250对应的位置，有机层130靠近液晶层300的表面设置凹槽，凹槽的深度H范围为0.4-0.6微米，凹槽的宽度W范围为0.7-2.5微米，相邻凹槽之间的凸起的宽度S范围为0.7-2.5微米。由于有机层130的厚度在2-3微米范围内，因此该凹槽的设置在不影响有机层130绝缘效果的情况下，使有机层130的表面具有了凹凸不平的结构。有机层130上的凹槽可以通过图案化处理得到，该图案化处理方法可以通过在现有工艺的基础上改变有机层制程中的掩膜版实现，无需额外增加光罩次数或改变工艺制程，节省了制作步骤，降低了生产成本。具体的图案化处理方法可以借鉴本领域技术人员所熟知的处理手段，在此不再赘述。由于有机层130靠近液晶层300的表面设置凹槽结构，当第二阵列层140形成于有机层130上时，在有机层130凹槽的位置也会形成相对应的凹槽结构，如图1所示，又由于有机层凹槽的深度H范围为0.4-0.6微米，凹槽的宽度W范围为0.7-2.5微米，相邻凹槽之间的凸起的宽度S范围为0.7-2.5微米，而第二阵列层140的厚度在0.3微米左右，因此第二阵列层140同样会形成形状和尺寸等同的凹槽结构。同理，当第一配向层150形成于第二阵列层140上时，第一配向层150同样会形成形状和尺寸等同的凹槽结构。这样，依次层叠设置的有机层130、第二阵列层140和第一配向层150共同构成凹凸结构，即形成第一基板100靠近支撑柱250的滑动阻尼结构101。
在一种实施例中，如图2至图4所示，滑动阻尼结构101所在的区域比支撑柱250与第一基板100接触的区域102（图中虚线所在围成的区域）或支撑柱250在第一基板100上的投影区域102（图中虚线所在围成的区域）大，且滑动阻尼结构101所在的区域包括支撑柱250在第一基板100上的投影区域。更进一步，在区域102之外，滑动阻尼结构101还包括至少一组凹槽和凸起，以保证支撑柱250在受到外力发生滑移时，在滑移方向上有足够多的滑动阻尼结构提供滑动阻力。在本申请实施例提供的液晶显示面板中，支撑柱250为柱状支撑结构，且通常为规则的柱状结构，可以是圆柱状，也可以是多棱柱状，本申请实施例以六棱柱状为例，以具体的实施例结合附图对本申请实施例提供的显示面板进行详细说明。
在一种实施例中，如图2所示，滑动阻尼结构101的凹槽112为环形凹槽。优选的，环形凹槽112以支撑柱250的中心线为中心对称设置，环形凹槽112包括间隔设置的多个同心环形凹槽，各个环形凹槽的内外周形状均与支撑柱250的外周形状相同，为正六边形，各个环形凹槽的内外直径均不相同，环形凹槽112的宽度范围为0.7-2.5微米，相邻两个环形凹槽112之间的凸起111的宽度范围为0.7-2.5微米。本实施例通过在第一基板100靠近支撑柱250的表面设置环形滑动阻尼结构，保证了支撑柱250在受到外部压力产生相对第一基板100表面的滑移动作时，支撑柱250与第一基板100接触的表面的各个位置都会受到环形滑动阻尼结构的阻挡，从而使支撑柱250相对于第一基板100任何方向的滑移动作都会受到较大的阻力，从而阻碍了支撑柱250相对于第一基板100表面的滑移动作，减小了支撑柱250在第一基板100表面的滑移量，缓解了支撑柱250滑移至像素透光区PA损伤像素透光区PA内的第一配向层150的风险，提高了液晶显示面板的抗按压能力及产品良率。如图2所示，环形凹槽112不仅包括支撑柱250对应区域102内的环形凹槽，还包括支撑柱250对应区域102外的环形凹槽，这样保证了更大范围的凹凸结构设置，更大程度的提高了支撑柱250相对于第一基板100表面的滑移阻力，能更加有效的减小了支撑柱250相对于第一基板100表面的滑移量，缓解支了撑柱滑移损伤像素透光区PA内的第一配向层150的风险，提高了液晶显示面板的抗按压能力及产品良率。在本实施例提供的液晶显示面板中，环形凹槽112还可以是圆环、四边形、十二边形等形状的环形凹槽，在此不做限定。在本实施例提供的液晶显示面板中，环形凹槽112也可以关于支撑柱250的中心线呈非对称设置，在此也不做限定。
在另一种实施例中，如图3所示，滑动阻尼结构101的凹槽112为网格线型凹槽。优选的，网格线型凹槽112以支撑柱250的中心线为中心对称设置，网格线型凹槽112所在的区域包括且大于支撑柱250对应的区域102，网格线型凹槽112围成的区域形成凸起111。各凸起111的形状可以是如支撑柱250相同的六边形，也可以是圆形或其他多边形，所有凸起111的尺寸可以相同，也可以存在至少两个凸起111的形状或尺寸不相同。凸起111的宽度范围为0.7-2.5微米，网格线型凹槽112的宽度范围为0.7-2.5微米。本实施例通过在第一基板100靠近支撑柱250的表面设置网格型滑动阻尼结构，保证了支撑柱250在受到外部压力产生相对第一基板100表面的滑移动作时，受到网格型滑动阻尼结构的阻挡，从而使支撑柱250相对于第一基板100的滑移动作受到较大的阻力，从而阻碍了支撑柱250相对于第一基板100表面的滑移动作，减小了支撑柱250在第一基板100表面的滑移量，缓解了支撑柱250滑移至像素透光区PA损伤像素透光区PA内的第一配向层150的风险，提高了液晶显示面板的抗按压能力及产品良率。
在又一种实施例中，滑动阻尼结构101的凹槽112为相互间隔的圆形或多边形凹槽，如图4所示，凹槽112的平面形状为与支撑柱250形状相同的六边形。优选的，六边形凹槽112关于支撑柱250的中心线中心对称设置，六边形凹槽112所占据的区域包括且大于支撑柱250对应的区域102，相邻六边形凹槽112之间的区域形成凸起111。在一种实施方案中，所有六边形凹槽112的尺寸均相同；在另一种实施方案中，存在至少两个六边形凹槽112的尺寸不同。在一种实施方案中，任意两个相邻的六边形凹槽112之间的距离相等；在另一种实施方案中，存在至少两个相邻的六边形凹槽112，该相邻两个六边形凹槽112之间的距离不相等。六边形凹槽112的宽度范围为0.7-2.5微米，凸起111的宽度范围为0.7-2.5微米。在本实施例提供的液晶显示面板中，还可以存在至少两个不同的凹槽，所述两个凹槽的形状不同，在此不做限定。本实施例通过在第一基板100靠近支撑柱250的表面设置包括独立凹槽的滑动阻尼结构，保证了支撑柱250在受到外部压力产生相对第一基板100表面的滑移动作时，受到滑动阻尼结构的阻挡，从而使支撑柱250相对于第一基板100的滑移动作受到较大的阻力，从而阻碍了支撑柱250相对于第一基板100表面的滑移动作，减小了支撑柱250在第一基板100表面的滑移量，缓解了支撑柱250滑移至像素透光区PA损伤像素透光区PA内的第一配向层150的风险，提高了液晶显示面板的抗按压能力及产品良率。
在其他实施例中，滑动阻尼结构101的凹槽112还可以包括环形凹槽、网格线型凹槽、以及多边形/圆形凹槽中的至少两种。
相应的，本申请实施例还提供一种显示装置，该显示装置包括本申请实施例提供的任意一种液晶显示面板，具备本申请实施例提供的任意一种液晶显示面板的技术特征和技术效果，具体实施方式及工作原理请参照上述具体实施例，在此不再赘述。
综上所述，本申请实施例提供一种液晶显示面板及显示装置，该液晶显示面板包括第一基板、第二基板、以及填充于第一基板和第二基板之间的液晶层，第二基板包括位于液晶层侧的支撑柱，在支撑柱对应的位置，第一基板靠近液晶层的表面设有滑动阻尼结构。该液晶显示面板通过在第一基板靠近液晶层的表面设置滑动阻尼结构，增大了支撑柱在受到外部压力时沿第一基板表面发生滑移的阻力，减小了支撑柱侧滑的滑移量，缓解了支撑柱滑移损伤像素透光区内的配向层的风险，提高了液晶显示面板的抗按压能力及产品良率。同时，支撑柱滑移量的减小，有助于减小黑矩阵层对支撑柱的遮光量，提高液晶显示面板的开口率和穿透率，降低液晶显示面板的背光成本。另外，滑动阻尼结构的制备无需额外增加光罩次数或改变工艺制程，节省了制作步骤，降低了生产成本。
以上对本申请实施例所提供的液晶显示面板及显示装置进行了详细介绍，本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的方法及其核心思想；同时，对于本领域的技术人员，依据本申请的思想，在具体实施方式及应用范围上均会有改变之处，综上所述，本说明书内容不应理解为对本申请的限制。
