 附图说明
为了更清楚地说明实施例或现有技术中的技术方案，下面将对实施例或现有技术描述中所需要使用的附图作简单介绍，显而易见地，下面描述中的附图仅仅是申请的一些实施例，对于本领域普通技术人员来讲，在不付出创造性劳动的前提下，还可以根据这些附图获得其他的附图。
图1为本申请实施例提供液晶显示面板的结构示意图。
图2为图1所示的液晶显示面板沿A-B方向的截面示意图。
 本发明的实施方式
下面详细描述本申请的实施方式，所述实施方式的示例在附图中示出，其中自始至终相同或类似的标号表示相同或类似的元件或具有相同或类似功能的元件。下面通过参考附图描述的实施方式是示例性的，仅用于解释本申请，而不能理解为对本申请的限制。
在本申请的描述中，需要理解的是，术语“中心”、“纵向”、“横向”、“长度”、“宽度”、“厚度”、“上”、“下”、“前”、“后”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”、“顺时针”、“逆时针”等指示的方位或位置关系为基于附图所示的方位或位置关系，仅是为了便于描述本申请和简化描述，而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。此外，术语“第一”、“第二”仅用于描述目的，而不能理解为指示或暗示相对重要性或者隐含指明所指示的技术特征的数量。由此，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个所述特征。在本申请的描述中，“多个”的含义是两个或两个以上，除非另有明确具体的限定。
请参阅图1、图2，图1为本申请实施例提供液晶显示面板的平面示意图；图2为图1所示的液晶显示面板沿A-B方向的截面示意图。如图1、图2所示，该液晶显示面板100，包括：阵列基板10、彩膜基板20、液晶层（图中未标示）以及多个衬垫结构30。其中，液晶层设置在阵列基板10和彩膜基板20之间。多个衬底结构30设置在阵列基板和彩膜基板之间。
该液晶显示面板100具有一显示区域101和以及透光功能区域102，多个衬垫结构30对应设置在显示区域101上。也即，本申请实施例的液晶显示面板100仅在对应显示区域101的位置上设置衬垫结构30，而在对应透光功能区域102的位置上则不设置衬垫结构30。在一种实施例方式中，多个衬垫结构30可间隔设在显示区域101上，从而可以保证液晶显示面板100各个位置上都均匀设置有衬垫结构30。
需要说明的是，本申请实施例中的透光功能区域102是在对应阵列基板10和彩膜基板20处形成一盲孔。也即，在该透光功能区域102上的阵列基板10和彩膜基板20仅仅保留玻璃基板。
其中，在一种实施方式中，该透光功能区域102上设置有摄像头、光传感器或者光发射器，该透光功能区域102用于供设置于该处下方的摄像头、光传感器或者光发射器采集光线。当然，其并不限于此。
其中，液晶层可对应设置在显示区域101处.当然，可以理解地，在一种实施方式中，透光功能区域102也可设置液晶层，在需要采光时，该透光功能区域102处的液晶层透明，不需要采光时，该透光功能区域102处的液晶层不透明。
在本申请实施例的液晶显示面板100中，该显示区域101包括设置在透光功能区域102周缘的预设区域1011。其中，设置在预设区域1011上的衬垫结构30的厚度沿着预设区域1011至透光功能区域102的方向逐渐减小。也即，本申请实施例的液晶显示面板100，通过将透光功能区,102附近的衬垫结构30的厚度逐渐降低，从而避免在透光功能区域102处产生干涉条纹，进而提高显示质量。
在一种实施方式中，在预设区域1011上，衬垫结构30的厚度沿着预设区域1011至透光功能区域102的方向均匀减小。在另一种实施方式中，在预设区域1011上，衬垫结构30的厚度沿着预设区域1011至透光功能区域102的方向按照预设值逐渐减小，其中，该预设值可以根据具体需要进行设置，在此不做限制。也即，本申请实施的液晶显示面板100可以提高透光功能区域102附近的平滑度，避免出现干涉条纹。
可以理解地，该透光功能区域102可以呈圆形状，对应地，该预设区域1011呈圆环状。也即，该预设区域1011与该透光功能区域102共圆设置，且预设区域1011的半径大于透光功能区域102的半径。具体地，该预设区域1011的半径与透光功能区域102的半径之差大于相邻两个衬垫结构30的间距值的3倍以上，可以为5倍或者6倍，以提高其间厚度渐变的衬垫结构30的数量，进而增强其平滑度。
需要说明的是，在一些实施例中，该透光功能区域102也可以呈椭圆形、矩形或者跑道形，对应的预设区域1011的形状与透光功能区域102的形状相同，且二者的中心重合。当然，其并不限于此。
具体的，请继续参阅图2，每一衬垫结构30的两端分别与阵列基板10和彩膜基板20连接。其中，每一衬垫结构30均包括黑色矩阵层31、光阻层32以及衬垫支撑层33。光阻层32设置在黑色矩阵层31上，衬垫支撑层33设置在光阻层32上，且黑色矩阵层31与彩膜基板20连接，衬垫支撑层33与阵列基板10连接。
进一步的，黑色矩阵层31上的光阻层32均呈扁平的柱状，该衬垫支撑层33呈上大下小的圆台状。其中，每一衬垫结构30的黑色矩阵层31、光阻层32以及衬垫支撑层33同轴设置。也即，每一衬垫结构30的黑色矩阵层31的宽度、光阻层32的宽度以及衬垫支撑层33的宽度依次减小。
在一种实施方式中，该黑色矩阵层31的厚度为0.08mm-0.11mm，该光阻层32的厚度为0.05mm-0.10mm，该衬垫支撑层33的厚度为0.23mm-0.25mm。当然，其并不限于此，也可以为采用其他更优的厚度组合。
在本申请实施例的液晶显示面板100中，每一衬垫结构30的黑色矩阵层31的厚度相同，每一衬垫结构30的光阻层32厚度相同，在预设区域1011上，衬垫支撑层33的厚度沿着预设区域1011至透光功能区域102的方向逐渐减小。也即，本申请实施例的液晶显示面板100，通过将透光功能区,102附近的衬垫结构30中的衬垫支撑层33的厚度逐渐降低，从而避免在透光功能区域102处产生干涉条纹，进而提高显示质量。
在一种实施方式中，在预设区域1011上，衬垫结构30中的衬垫支撑层33的厚度沿着预设区域1011至透光功能区域102的方向均匀减小。在另一种实施方式中，在预设区域1011上，衬垫结构30中的衬垫支撑层33的厚度沿着预设区域1011至透光功能区域102的方向按照预设值逐渐减小，其中，该预设值可以根据具体需要进行设置，在此不做限制。也即，本申请实施的液晶显示面板100可以提高透光功能区域102附近的平滑度，避免出现干涉条纹。
另外，需要说明的是，显示区域101还包括设置在预设区域外的第一显示区域1012，在第一显示区域1012上，每一衬垫结构30的厚度均相等。也即，设置在第一显示区域上的衬垫结构中，每一衬垫结构30的黑色矩阵层31的厚度相同，每一衬垫结构30的光阻层32厚度相同，每一衬垫结构30的衬垫支撑层的厚度相同。
本申请还提供了一种液晶显示装置，包括上述所述的液晶显示面板。本申请实施例提供的液晶显示装置，通过将透光功能区域附近的衬垫结构的厚度逐渐降低，从而在透光的盲孔处产生干涉条纹，进而可以提高显示质量。
在本说明书的描述中，参考术语“一个实施方式”、“某些实施方式”、“示意性实施方式”、“示例”、“具体示例”、或“一些示例”等的描述意指结合所述实施方式或示例描述的具体特征、结构、材料或者特点包含于本实用新型的至少一个实施方式或示例中。在本说明书中，对上述术语的示意性表述不一定指的是相同的实施方式或示例。而且，描述的具体特征、结构、材料或者特点可以在任何的一个或多个实施方式或示例中以合适的方式结合。
虽然本申请已以优选实施例揭露如上，但上述优选实施例并非用以限制本申请，本领域的普通技术人员，在不脱离本申请的精神和范围内，均可作各种更动与润饰，因此本申请的保护范围以权利要求界定的范围为准。
