具体实施方式
下面将结合本申请实施例中的附图，对本申请实施例中的技术方案进行清楚、完整地描述，显然，所描述的实施例仅仅是本申请的一部分实施例，而不是全部的实施例。基于本申请中的实施例，本领域普通技术人员在没有作出创造性劳动前提下所获得的所有其他实施例，都属于本申请保护的范围。
需要说明，本申请实施例中所有方向性指示（诸如上、下、左、右、前、后……）仅用于解释在某一特定姿态（如附图所示）下各部件之间的相对位置关系、运动情况等，如果该特定姿态发生改变时，则该方向性指示也相应地随之改变。
在本申请中，除非另有明确的规定和限定，术语“连接”、“固定”等应做广义理解，例如，“固定”可以是固定连接，也可以是可拆卸连接，或成一体；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通或两个元件的相互作用关系，除非另有明确的限定。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
另外，在本申请中如涉及“第一”、“第二”等的描述仅用于描述目的，而不能理解为指示或暗示其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至少一个该特征。另外，各个实施例之间的技术方案可以相互结合，但是必须是以本领域普通技术人员能够实现为基础，当技术方案的结合出现相互矛盾或无法实现时应当认为这种技术方案的结合不存在，也不在本申请要求的保护范围之内。
本申请提出一种彩色滤光片100。请结合参照图1至图3，在液晶显示器的液晶面板中彩色滤光片100与阵列基板200相对设置，阵列基板200包括玻璃基板210和覆盖在玻璃基板210上的导电膜220，遮光隔垫物125位于彩色滤光片100与阵列基板200之间，用以对彩色滤光片100和阵列基板200进行支撑以确保彩色滤光片100和阵列基板200之间具有合适的间距。该遮光隔垫物125能对彩色滤光片100与阵列基板200之间的流动的液晶层起到均匀的作用，且能保证液晶的填充量，防止液晶滴下量误差对产品造成的不良影响。
本申请的彩色滤光片100，包括基板100、黑色矩阵120、彩色滤光层130，黑色矩阵120设置于基板100的一表面，黑色矩阵120围出间隔设置的多个子像素区，子像素区包括第一子像素区121、第二子像素区122、及第三子像素区123；彩色滤光层130包括第一色阻层131、第二色阻层132、以及第三色阻层133，其中部分第一色阻层131、部分第二色阻层132、及所述第三色阻层133分别位于第一子像素区121、第二子像素区122、及第三子像素区123；另一部分第一色阻层131、另一部分第二色阻层132、及另一部分第三色阻层133于对应黑色矩阵120的边框位置堆叠以形成遮光隔垫物125，且遮光隔垫物125至少部分嵌入黑色矩阵120。
基板100可以为塑料、树脂、玻璃等材质。在彩色滤光片100制作过程中，首先对基板100进行清洗，然后提供黑色光阻材料，在基板100上涂布黑色光阻材料，黑色光阻材料可以是Cr金属，也可以是掺入黑色颜料（主要是碳）的丙烯树脂，如在光刻胶中掺入碳、Ti、Ni等原料形成黑色树脂。利用光罩对黑色光阻材料进行曝光、显影，制得黑色矩阵120。本申请的第一色阻层131为红色色阻层，第二色阻层132为绿色色阻层，第三色阻层133为蓝色色阻层。采用半色调光照对第一色阻层131、第二色阻层132、以及第三色阻层133分别进行曝光、显影，依次制得位于第一子像素区121内的红色色阻层、位于第二子像素区122内的绿色色阻层、以及位于第三子像素区123内的蓝色色阻层，在此制备彩色滤光层130的制程中，部分红色色阻层、部分绿色色阻层、以及部分蓝色色阻层在黑色矩阵120上堆叠形成遮光隔垫物125。本申请是在制备彩色滤光层130的同时形成遮光隔垫物125，可以理解的，基于三基色原理，红色色阻层、绿色色阻层、以及蓝色色阻层层叠后具有不透光的属性，因此能够有效的在黑色矩阵120处进行遮光。在其他实施例中，遮光隔垫物125还可以是在上述三个色阻层进行堆叠的基础上，再在相邻两个色阻层之间夹持一个遮光材料制作的遮光层来形成。
本申请技术方案通过在制作彩色滤光层130的过程中通过多个色阻层的堆叠的方式制得遮光隔垫物125，使得隔垫物与彩色滤光层130能够在同一制程中形成，从而能够节省一道单独制作隔垫物的工艺制程，节省了制作隔垫物的光阻材料与光罩，从而降低了生产成本，并提高了生产效率和生产产能。进一步地，本申请在制作遮光隔垫物125过程中，将遮光隔垫物125至少部分嵌入到黑色矩阵120中，如此在色阻层材料较厚的基础上，也可以有效控制具有本申请彩色滤光片100的显示面板300的间隙（盒厚），使得显示面板300的品质得到保障。
本申请将遮光隔垫物125嵌入到黑色矩阵120内可以有效的调节遮光隔垫物125的高度，确保显示面板300中彩色滤光片100和阵列基板200之间的间隙，具体的，请继续参照图1至图3，在一些实施例中，黑色矩阵120开设有连通两相邻子像素区的缺口124，缺口124在黑色矩阵120的厚度方向上延伸至基板100，遮光隔垫物125嵌入缺口124内。其中缺口124可以在黑色矩阵120制程过程中形成，由于本申请的遮光隔垫物125是由红色色阻层、绿色色阻层、以及蓝色色阻层三种色阻堆叠而成具有不透光的属性，缺口124延伸至基板100的情况下遮光隔垫物125也可以对黑色矩阵120处进行遮光，从而不会影响整个显示面板300的品质，通过缺口124的设计可以有效控制显示面板300的盒厚。并且有利于整个彩色滤光片100的制作完成。
进一步地，本申请通过在黑色矩阵120上设置缺口124来嵌设遮光隔垫物125的基础上，遮光隔垫物125可以设置有多个，遮光隔垫物125可以在黑色矩阵120上均匀间隔分布并且可以设置在红色色阻层、绿色色阻层，或者蓝色色阻层的之前其中之一对应黑色矩阵120的边框处，如附图1至3所展示的方案即为遮光隔垫物125在蓝色色阻层（BLUE，附图中对应B）位置的黑色矩阵120的边框处进行堆叠。如附图4至6所展现的方案为遮光隔垫物125在绿色色阻层（GREED，附图中对应G）位置处进行堆叠，如附图7至图9所展现的方案为遮光隔垫物125在红色色阻层（RED，附图中对应R）位置处进行堆叠，其具体过程可以为，在制作黑色矩阵120的光刻和显影的制程中，形成缺口124，然后对制作红色色阻层、绿色色阻层，以及蓝色色阻层的光刻和显影的过程中，部分红色色阻层、绿色色阻层，以及蓝色色阻层的材料在缺口124处进行依次堆叠形成遮光隔垫物125，当遮光隔垫物125在蓝色色阻层位置的黑色矩阵120的边框处进行堆叠时，蓝色色阻层位于缺口124处的部分连通两个相邻第三子像素区123内的蓝色色阻层，而缺口124内的部分红色色阻层和部分绿色色阻层则单独以缺口124的面积大小存在，当遮光隔垫物125在其他色阻层位置堆叠时刻参照在蓝色色阻层堆叠的结构，在此不再赘述。
请参照图10，在本申请另一些实施例中，黑色矩阵120还可以凹设形成有凹槽124a，遮光隔垫物125嵌入凹槽124a内，在本实施例中凹槽124a和基板100之间有部分黑色矩阵120的材料作为凹槽124a的底壁进行隔开。其中凹槽124a的形成可以是在黑色矩阵120制程过程中，在光刻过程改变光刻的光照强度以在厚度方向上保留部分黑色矩阵120的材料，通过设置凹槽124a，有利于增加遮光隔垫物125的高度，满足显示面板300的盒厚需求。
进一步地，所述遮光隔垫物125于基板100上的正投影位于黑色矩阵120位于基板100上的正投影范围内。通过这样的设置，可以避免遮光隔垫物125影响像素的开口率。
本申请遮光隔垫物125的剖面形状为梯形或矩形。本申请可选择将遮光隔垫物125的剖面形状设计为梯形，这样的设计使得遮光隔垫物125在支撑彩色滤光片100和阵列基板200时能够支撑更稳定。
本申请在制作彩色滤光层130过程中同时形成通过红色色阻层、绿色色阻层、以及蓝色色阻层依次层叠形成的遮光隔垫物125，接下来进行在彩色滤光层130上形成电极层，并且遮光隔垫物125上也覆盖有电极层。
请再次参照图1至图10，本申请还提出一种显示面板300，显示面板300包括对盒设置的彩色滤光片100和矩阵基板100，该彩色滤光片100的具体结构参照上述实施例，由于本显示面板300采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上所述仅为本申请的可选实施例，并非因此限制本申请的专利范围，凡是在本申请的发明构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
