请参考图1，图1是本申请一种显示面板第一实施方式的结构示意图，所述显示面板包括：
彩膜基板10；阵列基板20，与所述彩膜基板10对应设置，且包括两个金属层21；液晶层30，夹设在所述彩膜基板10和所述阵列基板20之间；其中，靠近观看者40的所述金属层21上设置反射阻挡层22，以降低所述阵列基板20对环境光的反射率。
本实施方式在对环境光反射强烈的金属层21上覆盖一反射阻挡层22，能够有效减少朝向观看者40的金属层21对环境光的反射，进而提高显示对比度，有利于提高所述观看者40的观看体验。
具体的，所述显示面板可以是所述彩膜基板10侧朝向观看者40(也即所述彩膜基板10朝外，环境光从所述彩膜基板10一侧入射)，也可以是所述阵列基板20侧朝向观看者40(也即所述阵列基板20朝外，环境光从所述阵列基板20一侧入射)。所述反射阻挡层22为黑色，能够减少所述金属层21对环境光的反射。进一步的，所述反射阻挡层22可以设置在所述两个金属层21上，也可以根据所述阵列基板20是否朝向观看者40，所述反射阻挡层22仅设置在某一所述金属层21上。为了进一步简化生产工艺并降低成本，所述反射阻挡层22设置在朝向观看者40的所述金属层21上。
在一个实施方式中，请参考图2，图2是本申请一种显示面板第二实施方式的结构示意图，所述阵列基板200朝向观看者400，此时，所述阵列基板200包括：支撑基板210；依次设置在所述支撑基板210上的第一金属层220、第一绝缘层230、有源层240及第二金属层260；所述反射阻挡层270设置在所述支撑基板210与所述第一金属层220之间。

由于所述阵列基板200朝向观看者400，则所述第一金属层220反射的环境光对观看者400的观看体验影响较大，则将所述反射阻挡层270设置在所述支撑基板210与所述第一金属层220之间，能够有效减少所述第一金属层220对环境光的反射，进而有效提升观看体验。进一步的，为获得较好的效果，所述反射阻挡层270的尺寸至少覆盖所述第一金属层220。更进一步的，为进一步降低成本，所述反射阻挡层270的尺寸恰好覆盖所述第一金属层220，以使所述第一金属层220基本不反射环境光。
在另一个实施例中，请参考图3，区别于图2中的实施例，所述反射阻挡层270还设置在所述第二金属层260与所述有源层240之间，本实施方式在两个位置对反射光进行阻挡，能够获得更好的显示效果。
进一步的，请参考图4，图4是本申请一种显示面板第四实施方式的结构示意图，所述显示面板还包括：第一中间层280，设置在所述反射阻挡层270与所述第一金属层220之间，以提高所述反射阻挡层270与所述第一金属层220之间的附着力。具体的，所述中间层280可以为氮化硅和/或氧化硅等。进一步的，所述显示面板还包括：第二中间层250，设置在所述反射阻挡层270与所述第二金属层260之间，以提高所述反射阻挡层270与所述第二金属层260之间的附着力。具体的，所述第二中间层250可以为氮化硅和/或氧化硅等。
在另一个实施方式中，请参考图5，图5是本申请一种显示面板第五实施方式的结构示意图，所述阵列基板200远离观看者400，此时，所述阵列基板200包括：支撑基板210；依次设置在所述支撑基板210上的第一金属层220、第一绝缘层230、有源层240及第二金 属层260；所述反射阻挡层270设置在所述第二金属层260上。
在本实施方式中，所述阵列基板200远离观看者400，则所述第二金属层260反射的环境光对观看者400的观看体验影响较大，则将所述反射阻挡层270设置在所述第二金属层260上，能够有效减少所述第二金属层260对环境光的反射，进而有效提升观看体验。进一步的，为获得较好的效果，所述反射阻挡层270的尺寸至少覆盖所述第二金属层260。更进一步的，为进一步降低成本，所述反射阻挡层270的尺寸恰好覆盖所述第二金属层260，以使所述第二金属层260基本不反射环境光。
在另一个实施例中，请参考图6，区别于图5中的实施例，所述反射阻挡层270还设置在所述第一金属层220上，具体的，设置在所述第一金属层220于所述第一绝缘层230之间。本实施方式在两个位置对反射光进行阻挡，能够获得更好的显示效果。
进一步的，所述显示面板200还包括：钝化层(图未示)，设置在所述反射阻挡层270与所述第二金属层260之间，以简化制备工艺。在本实施方式中，所述钝化层可以提高显示效果并延长所述显示面板200的使用寿命，可采用涂敷等方式形成，其材质可以为有机材料或无机材料。当所述钝化的材料为无机材料时，其具体可以为氮化硅或氧化硅，也可以是二者的复合物。当所述钝化层的材料为有机材料时，其可以为树脂系列绝缘膜或亚克力系列绝缘膜等。更近一步的，在所述钝化层上设置所述反射阻挡层270则不需在所述钝化层上设置黑矩阵(设置在所述钝化层上的所述反射阻挡层270起到黑矩阵的作用)，则通过一次黄光制程就可制备所有的遮光层，有利于进一步简化工序和降低成本。
具体的，所述反射阻挡层270包括：树脂和染料，所述染料包括苝二聚体染料或者该染料与炭黑的混合物；

Figure PCTCN2019125940-appb-000004
在本实施方式中，所述反射阻挡层270为黑色阻挡层，能够有效减少所述金属层对环境光的反射。具体的，所述反射阻挡层270的材质可以是黑色光刻胶，其包括树脂和染料。所述树脂须具有耐热性，避免在制备所述反射阻挡层270的过程中因高温烘烤破坏其结构，进而影响使用效果。如，所述树脂可以为聚酰亚胺树脂。为简化工艺并获得较好的效果，所述染料需在常用的溶剂(如，单甲基醚丙二醇乙酸酯(PGMEA))中具有较好的溶解性、耐热性及吸光度性质。相应的，所述染料可以为苝二聚体染料或者该染料与炭黑的混合物，其中，所述苝二聚体的耐热性优异，其耐受温度可达到320摄氏度。更进一步的，所述苝二聚体的结构式中的两个R可以是相同的结构或不同的结构。当二者结构不同时，其至少包括a与d、a与e、b与d、c与d及c与e中的一组，且采用上述任意组合能够进一步提高所述反射阻挡层的效果。
