例如，如图1至图3所示，像素限定层200的开口210在衬底基板10上的正投影位于相应的发光层1300在衬底基板10上的正投影内，即发光层1300覆盖了像素限定层200的开口210。例如，发光层1300的面积大于对应的像素限定层200的开口210的面积，即发光层1300除位于像素限定层200的开口210内部的部分，至少还包括覆盖像素限定层200的实体结构上的部分。通常在像素限定层200的开口210的各个边界处的像素限定层200的实体结构上均覆盖发光层1300。
如图1至图3所示，多个隔垫物300分布在像素限定层200的相邻开口210之间的间隔处。例如，上述间隔指相邻开口210之间的像素限定层200的实体结构，例如，隔垫物300位于像素限定层200的实体结构上。
例如，如图1至图3所示，本公开实施例以像素限定层200与隔垫物300为两个彼此独立的结构，但不限于此，隔垫物与像素限定层可以为一体结构，例如在同一步图案化工艺中一体形成，无明显界限。例如，隔垫物和像素限定层可以以坡度角曲线出现拐点的位置作为界限。例如对于像素限定层本身，从位于其延伸方向中心线两侧的一开口边缘到靠近像素限定层延伸方向中心线的方向，坡度角可以是从大到小的趋势，到像素限定层接近平坦的表面，坡度角可以大致为0°到5°；在像素限定层接近平坦的表面上，到隔垫物的边界处，坡度角又呈现上升的趋势，例如隔垫物边界处，坡度角可以大致为从接近0°上升到10°左右(例如为5°～10°)，或10°以上。上述坡度角可以为测量点位置做外切线，与最靠近的第二电极(例如为阳极)远离衬底基板的表面所在的平面之间的夹角。例如，未设置隔垫物的像素限定层部分的厚度为第一厚度(例如接近平坦的部分的平均厚度)，设置有隔垫物的像素限定层部分的最大厚度为第二厚度，隔垫物和像素限定层的边界，可以按照从像素限定层靠近衬底基板一侧的表面起到第一厚度之间的部分为像素限定层本身，超过第一厚度到第二厚度的部分为隔垫物的部分。例如，第一厚度(例如接近平坦的部分的平均厚度)可以为0.8-1.8μm。例如，第一厚度可以大于等于1.1μm。例如，第一厚度可以小于3μm。因为像素限定层作为封装有机层阻挡坝的一部分，厚度太小，可能容易出现有机层溢流影响封装效果。像素限定层的第一厚度太厚，容易对出光角度造成比较大的限制，影响出光效率。
例如，像素限定层200的靠近开口210的部分的坡度角可以为15°-25°。 例如，像素限定层200的靠近开口210的部分的坡度角可以为17°-21°。例如，像素限定层200的靠近开口210的部分的坡度角可以为18°-20°。
例如，图3示意性的示出隔垫物设置在像素限定层上，但不限于此，隔垫物还可以设置在其他膜层上，例如隔垫物可以设置在对置基板上。
图4A为图2所示一个开口的形状示意图。如图1至图4A所示，至少一个开口210的形状为多边形400截去至少一个顶角401后的形状，开口210的角部包括第一角部1011，第一角部1011为多边形400被截去由两条边410所夹的一顶角401后形成的第一角部1011。例如，用于截去多边形400的顶角401的截线402可以包括曲线、直线等具有规则形状的线段，也可以为不规则形状的线段。
例如，各个开口210的每条边或其延长线依次连接形成多边形400，且至少部分多边形400的多个顶角存在与对应的开口的多个角部不交叠的区域；至少一个开口210的多个角部中，至少包括第一角部1011，所述第一角部1011和与其对应的所述多边形400的顶角不交叠的区域的面积大于其他角部的至少部分角部中各角部和与该角部对应的多边形400的顶角不交叠的区域的面积。
例如，本公开实施例示意性的示出多边形400为四边形，例如，对应于至少一个开口210的多边形400的形状可以为菱形、矩形或者正方形，但不限于此，多边形400还可以为三角形、五边形或者六边形等，本公开实施例对此不作限制。例如，多边形的各角部的角度可以相等，也可以不等。
例如，如图4A所示，第一角部1011包括一顶点P，该顶点可以在连线403上，与第一角部1011的两端连接的两条边向其顶点P延伸交汇的部分形成的一段曲线(即角部的外侧边缘)以使得该第一角部1011成为圆倒角，此时，该第一角部1011可为从该顶点P为中心沿轮廓x微米的范围，x微米的值可以为2～7微米。例如，所述开口210的角部还包括第二角部1012，连接所述第一角部1011的两端点的两条边或其延长线的交点到该开口210的几何中心的距离大于构成所述第二角部1012的两条边或其延长线的交点到该开口210的几何中心的距离。例如，在第一角部为圆倒角，开口的形状中与第一角部相对的角部(例如第二角部)为直角或锐角时，与第一角部的两端连接的两条直边的延长线的交点到该开口210的几何中心O的距离大于构成与第一角部相对的角部的两条直边的延长线的交点到该几何中心O的距离。
上述“圆倒角”为一段曲线形成的角部，该曲线可以为圆弧，也可以为非 规则的曲线，例如椭圆形中截取的曲线、波浪线等。本公开实施例示意性的示出该曲线具有相对于开口210的几何中心O向外凸的形状，但不限于此，该曲线也可以具有相对于开口210的几何中心O向内凹的形状。例如，曲线为向外凸的圆弧时，该圆弧的圆心角的范围可以为10°～150°。例如，该圆弧的圆心角的范围可以为60°～120°。例如，该圆弧的圆心角的范围可以为90°。例如，第一角部1011包括的圆倒角的曲线长度可以为10～60微米。
例如，第一角部1011为圆倒角时，其曲率半径可以为5～20微米。
例如，图4B为另一种发光区形状的示意图。如图4B所示，上述第一角部也可以为构成某一顶角的两条边向其顶点P延伸交汇的部分形成的线段(即角部的外侧边缘)以使得该第一角部成为平倒角，例如第一角部1011包括平倒角，该第一角部的顶点可以在连线403上，例如为连线403与平倒角的交点。
如图1至图4A所示，至少一个隔垫物300设置在第一角部1011和与其相邻的开口210之间的间隔处，且该第一角部1011位于其所在开口210的几何中心靠近该相邻的开口210的一侧以使该第一角部1011朝向该相邻的开口210。上述第一角部1011的外侧边缘为向外凸的曲线时，第一角部1011朝向该相邻的开口指第一角部1011的外侧边缘向该相邻的开口凸出。
如图1至图4A所示，所述第一角部1011所在开201口的几何中心与该相邻的开口210的几何中心的连线C01经过所述第一角部1011和所述隔垫物300。
本公开实施例通过在第一角部对应的像素限定层的开口的间隔位置处设置隔垫物，有利于提升工艺良率或者提升隔垫物的支撑作用。上述“第一角部对应的像素限定层的开口的间隔位置”指与角部的外侧边缘相接的间隔。
本公开实施例在第一角部对应的间隔处设置隔垫物，可以增加隔垫物与开口之间的距离，和/或，增加隔垫物的尺寸，可以降低隔垫物脱落的几率，从而有利于提升产品的工艺良率。
在蒸镀形成子像素的发光层等膜层时，隔垫物可以起到支撑用于蒸镀发光层的精细金属掩模板(FMM)的作用，FMM具有多个通孔，通孔可为刻蚀方式形成的孔，蒸镀材料由下至上通过通孔沉积在像素限定层上。因FMM是金属材质，与衬底基板接触时，易损伤衬底基板上沉积的材料。为了避免FMM破坏显示基板中的膜层，在像素限定层上设置隔垫物以在蒸镀时支撑FMM，防止FMM划伤像素限定层等膜层的表面。蒸镀时，将衬底基板置于的上方， 隔垫物与FMM贴合。本公开实施例在角部对应的间隔处设置隔垫物，可以增加隔垫物与开口之间的距离，和/或，增加隔垫物的尺寸，有利于提升隔垫物对精细金属掩模板的支撑作用。
例如，如图1至图4A所示，一开口210中的第一角部1011朝向下(图2所示与Y方向的箭头所指方向相反的方向)，则该开口210的下侧的间隔处设置有隔垫物300。本公开实施例不限于此，一开口中的第一角部朝向上(图2所示与Y方向的箭头所指方向)，则该开口的上侧的间隔处设置有隔垫物；一开口中的第一角部朝向右(图2所示与X方向的箭头所指方向)，则该开口的右侧的间隔处设置有隔垫物；一开口中的第一角部朝向左(图2所示与X方向的箭头所指方向相反的方向)，则该开口的左侧的间隔处设置有隔垫物。本公开实施例中，一开口的第一角部的朝向不限于上述向上、向下、向左或者向右(这些朝向均与行方向和列方向大致平行)，还可以朝向倾斜的方向，该倾斜方向为与行方向和列方行均相交的方向，例如，倾斜方向与行方向之间的夹角可以为20～80度，或者30～70度，或者45～60度等。例如，开口的第一角部的朝向还可以斜向上(如斜向左上，或者斜向右上)、斜向下(如斜向左下，或者斜向右下)。
例如，如图1至图4A所示，隔垫物300在一方向上的两侧设置有两个彼此相邻的开口210，至少一个开口210设置有第一角部1011，且该第一角部1011位于该隔垫物300与该至少一个开口210的几何中心之间。
例如，如图1至图4A所示，与隔垫物300紧邻的至少一个开口210设置有第一角部1011，则该第一角部1011为该开口210的所有角部中最靠近该隔垫物300的一个角部。
例如，如图1至图4A所示，多边形400的两条边(例如第一边410)的至少之一被截去的部分的长度L1与该边410的长度之比为0.2～0.8。多边形400的第一边410被截去第一线段L1后剩余部分L2形成连接第一角部1011的开口210的边，例如第一角部1011的两端分别与开口210的两条直边连接，这两条直边的至少一条直边为多边形400的第一边410截去第一线段L1后剩余的直线边。
例如，多边形400可以被截去至少一个第一顶角401以形成至少一个第一角部1011。例如，一个多边形400包括的多个第一顶角401度数相等，且该多个第一顶角401被截去后形成的多个第一角部1011的形状和尺寸等参数均相 等。
例如，如图1和图4A所示，第一线段L1的长度与第一边410的长度之比为0.3～0.7。例如，第一线段L1的长度与第一边410的长度之比为0.4～0.6。例如，第一线段L1的长度与第一边410的长度之比为0.5。
例如，如图1和图4A所示，第一线段L1的长度与剩余部分L2的长度之比为0.25～4。例如，第一线段L1的长度与剩余部分L2的长度之比为1～3。第一线段L1的长度与剩余部分L2的长度之比为0.5～2。
例如，如图1至图4A所示，各隔垫物300设置在第一角部1011和与该第一角部1011相邻的开口210之间的间隔处。例如，所有隔垫物300均设置在靠近第一角部1011的间隔处，以进一步提高工艺良率以及隔垫物的支撑作用。
例如，如图1至图4A所示，具有第一角部1011的开口210的数量不小于多个隔垫物300的数量。例如，具有第一角部1011的开口210的数量大于多个隔垫物300的数量，具有第一角部1011的开口210中的部分开口210附近设置了隔垫物300，其他开口210的附近没有设置隔垫物300。当然本公开实施例不限于此，隔垫物也可以设置比较大的密度，例如隔垫物的数量可以与具有第一角部的开口的数量大致相等，例如设置有第一角部的开口的第一角部对应的间隔处均设置隔垫物。
例如，在相邻的开口210的中心连线的方向上，隔垫物300的尺寸与开口210之间的间隔的尺寸的比值可以为0.8-1.2。
例如，至少一个隔垫物300在平行于所述第一角部1011所在开口210的几何中心与该相邻的开口210的几何中心的所述连线C0的方向的最大尺寸为第一尺寸SZ1，在垂直于所述连线C0的方向的最大尺寸为第二尺寸SZ2，所述第一尺寸SZ1小于所述第二尺寸SZ2。
例如，至少一个隔垫物300的在衬底基板10上的正投影的形状为长条形，且所述长条形的短轴大致平行于所述第一角部1011所在开口的几何中心与该相邻的开口的几何中心的连线C0。
图2示意性的以隔垫物300在衬底基板10上的正投影的形状以矩形为例，矩形的长边为与开口210的第一角部1011相邻的边。
本公开实施例不限于隔垫物在衬底基板上的正投影的形状为矩形，例如，隔垫物在衬底基板上的正投影的形状还可以选自圆角矩形、椭圆形、圆形中的至少一种。例如，隔垫物在衬底基板上的正投影可以为轴对称图形。例如，隔 垫物位于像素限定层不同延伸方向的部分的交点处(例如覆盖像素限定层不同延伸方向的部分的交点)，且具有两个对称轴，该两个对称轴分别大致平行其所在处的像素限定层的两个延伸方向。例如，隔垫物在衬底基板上的正投影在其长轴方向尺寸范围可以为20-50μm。例如，隔垫物在衬底基板上的正投影在其短轴方向尺寸范围可以为12-30μm。例如，隔垫物在衬底基板上的正投影的范围小于48μm*26μm。例如，隔垫物在衬底基板上的正投影的范围小于41μm*25μm。例如，隔垫物在衬底基板上的正投影的范围小于33μm*20μm。例如，隔垫物在衬底基板上的正投影的范围小于25μm*15μm。
例如，如图1至图4A所示，具有第一角部1011的开口210被配置为限定至少一种颜色子像素100的发光区101。例如，至少一种颜色子像素100包括蓝色子像素、绿色子像素以及红色子像素的至少之一。图1至图4A示意性的示出被配置为限定一种颜色子像素的发光区的开口包括第一角部，但不限于此，被配置为限定其他颜色子像素的发光区的开口也可以包括第一角部，可以根据实际产品需要进行设置。
图5A为一种像素限定层以及隔垫物的平面结构示意图。如图5A所示，一种像素限定层020包括的各个开口021的形状均为多边形，且该多边形没有顶角被截去，隔垫物030位于相邻两个开口021的彼此相对的顶角0211和顶角0212之间的间隔处，且这两个顶角0211和0212均为非圆倒角或者非平倒角，例如可以为锐角或者直角等。如图5A所示，隔垫物030与两个顶角0211和0212之间的两个距离可以相等，例如均为S0。图5A示意性的示出隔垫物030与顶角0211(或顶角0212)之间的距离指隔垫物030靠近该顶角0211(或顶角0212)的边缘与该顶角0211(或顶角0212)的距离S0，但不限于此，隔垫物与顶角之间的距离还可以指隔垫物的几何中心与顶角之间的距离。如图5A所示，位于上述两个顶角0211和0212之间的隔垫物030在Y方向(包括上述两个顶角0211和0212的两个开口的排列方向)上的尺寸，如宽度为W0。
图5B为图2所示像素限定层以及隔垫物的一示例中部分平面结构示意图。如图5B所示，隔垫物300与位于其一侧的第一角部1011之间的距离为第一距离S1，隔垫物300与位于其另一侧的开口210的角部1013的最短距离为第二距离S2，第一距离S1不小于第二距离S2。例如，第一距离S1可以大于第二距离S2。例如，第一距离S1可以等于第二距离S2。
例如，图5B所示的具有角部1013的开口210的形状以及其与隔垫物300 的位置关系可以与图5A所示的具有顶角0212的开口021的形状以及其与隔垫物030的位置关系相同，则第二距离S2可以与距离S0相等。图5B所示的隔垫物300在两个开口210的排列方向(Y方向)上的尺寸W1与图5A所示的隔垫物030在两个开口021的排列方向(Y方向)上的尺寸W0可以大致相等。图5B所示的与隔垫物300紧邻的第一角部1011可以为图5A所示的与隔垫物030紧邻的顶角0211被截去后形成的第一角部1011(该顶角0211所在开口021可以为形成第一角部1011所在开口210的多边形)，则图5B所示的第一角部1011与隔垫物300之间的第一距离S1可以大于图5A所示的顶角0211与隔垫物030之间的距离S0，则第一距离S1大于第二距离S2，以增加隔垫物与一个开口之间的距离，有利于提高工艺良率。
例如，图5B所示位于隔垫物300在X方向的两侧的开口212的形状以及相对位置关系可以与图5A所示位于隔垫物030在X方向的两侧的开口的形状以及相对位置关系相同。例如，如图5B所示，位于隔垫物300在X方向的两侧的开口212相对于连线C0对称分布时，隔垫物300与在X方向上位于其两侧的两个开口212之间的两个距离相等。例如，位于隔垫物300在X方向的两侧的开口212可以均包括第一角部，也可以均不包括第一角部，本公开实施例对此不作限制。
例如，如图5B所示，围绕隔垫物300的开口210包括在行方向排列的两个开口和在列方向上排列的两个开口，上述四个开口210的至少之一包括第一角部1011，例如上述四个开口之一包括朝向隔垫物300的第一角部1011，隔垫物300与第一角部1011之间的距离为第一距离，隔垫物300和与第一角部1011所在开口在行或列方向排列的另一个开口210之间的距离为第二距离，隔垫物300与剩下的在列或行方向排列的两个开口210之间的距离分别为第三距离和第四距离。例如，位于隔垫物300在X方向的两侧的开口212与隔垫物300之间的距离可以分别为第三距离和第四距离，第三距离与第四距离可以相等，也可以不等。例如，第一距离可以大于第三距离，且第二距离、第三距离和第四距离可以均相等。例如，第一距离和第二距离相等，第三距离和第四距离相等，第一距离大于第三距离。
例如，在图5A中隔垫物030的尺寸W0与图5B中隔垫物300的尺寸W1相等时，可以通过调节图5B中隔垫物300与在Y方向上位于其两侧且紧邻的两个开口210之间的距离使得第一距离S1和第二距离S2基本相等，则第一距 离S1和第二距离S2均大于图5A所示的距离S0。本公开实施例可以通过调节隔垫物与开口之间的距离以增加隔垫物与位于其两侧的两个开口之间的距离，有利于降低隔垫物脱落的几率，以提高工艺良率。
图5C为图2所示像素限定层以及隔垫物的另一示例中部分平面结构示意图。如图5A所示，在X方向上位于隔垫物030两侧且与隔垫物030紧邻的两个开口021的彼此相对的角部0213和0214的连线L0经过隔垫物030的几何中心031。如图5C所示，隔垫物300与在X方向上位于其两侧的两个开口210之间的第一距离S1和第二距离S2可以均与图5A所示的距离S0相等，且图5C所示的隔垫物300在Y方向上的尺寸W1(如宽度)大于图5A所示的隔垫物030在Y方向上的尺寸W0，则本公开实施例在没有降低隔垫物与开口之间距离的基础上，通过增加隔垫物的尺寸，在保证工艺良率的基础上可以提高隔垫物的支撑作用。
图5C所示示例中，位于隔垫物300在Y方向(或X方向)上的一侧的开口210具有第一角部1011，该隔垫物300在Y方向(或X方向)上的另一侧的开口210不具有第一角部1011，而位于隔垫物300在X方向(或Y方向)上的两侧的开口210是对称分布的，可以均不具有第一角部1011，也可以均具有第一角部1011，且两个开口210中的第一角部1011是对称分布的。
例如，如图5C所示，在行方向和列方向至少之一上位于隔垫物300的两侧且与隔垫物300紧邻的两个开口210的彼此相对的角部1014和1015的连线L01位于该隔垫物300的几何中心301远离第一角部1011的一侧。
例如，第一距离、第二距离、第三距离以及第四距离可以均相等。
当然本公开实施例不限于上述隔垫物的尺寸以及隔垫物与开口之间的距离的设置。例如，还可以图5B所示的隔垫物300的尺寸W1大于图5A所示的隔垫物030的尺寸W0，且隔垫物300与至少一个开口之间的距离(第一距离和第二距离的至少之一)也大于图5A所示的隔垫物030与开口之间的距离S0，通过同时增加隔垫物的尺寸以及隔垫物与开口之间的距离，既有利于降低隔垫物脱落的几率，又有利于提升产品的工艺良率与隔垫物的支撑作用。
参考图5A至图5C，由于至少一个开口设置了第一角部，则该角部与位于相邻开口且与该第一角部相对的角部之间的距离增加了，此时，既可以仅增加隔垫物的尺寸，又可以仅增加隔垫物与开口之间的距离，还可以隔垫物的尺寸以及隔垫物与开口之间的距离均增加，从而，可以降低隔垫物脱落的几率，有 利于提升产品的工艺良率与隔垫物的支撑作用。
例如，图6为根据本公开实施例的另一示例提供的像素限定层以及隔垫物的平面结构示意图。如图6所示，例如，具有所述第一角部1011的所述开口210包括同一种类型的开口，例如，具有第一角部1011的开口210可以均包括一个第一角部1011，且各开口210中的第一角部1011的朝向均相同，例如，各开口210中的第一角部1011均朝向上，或者均朝向下，或均朝向右，或者均朝向左，或者均朝向(斜向)左上，或者均朝向(斜向)左下，或者均朝向(斜向)右上，或者均朝向(斜向)右下，则多个隔垫物300均分布在同一朝向的第一角部1011对应的间隔处。上述“同一种类型的开口”指角部的朝向相同的开口，该同一种类型的开口可以仅包括被配置为限定同一种颜色子像素的发光区的开口，也可以包括被配置为限定不同颜色子像素的发光区的开口。例如，同一种类型的开口可以仅包括限定蓝色子像素的发光区的开口、或者限定绿色子像素的发光区的开口，或者限定红色子像素的发光区的开口；也可以包括限定蓝色子像素的发光区的开口和限定绿色子像素的发光区的开口，或者限定蓝色子像素的发光区的开口和限定红色子像素的发光区的开口，或者限定绿色子像素的发光区的开口和限定红色子像素的发光区的开口；还可以包括限定蓝色子像素的发光区的开口、限定红色子像素的发光区的开口以及限定绿色子像素的发光区的开口。
图6示意性的示出被配置为限定一种颜色子像素的发光区的开口包括第一角部，但不限于此，被配置为限定其他颜色子像素的发光区的开口也可以包括第一角部，可以根据实际产品需要进行设置。
例如，如图1至图4A所示，具有第一角部1011且被配置为限定同一种颜色子像素100的发光区101的开口210包括至少两种类型开口，不同类型开口210中，第一角部1011的顶点指向与其相对的角部的顶点的方向不同。
本公开实施例中不同类型开口指角部的顶点指向与其相对的角部的顶点的方向不同的开口。例如，上述开口可以包括四个角部，此时，开口可以包括一个第一角部，三个其他角部之一与一个第一角部相对；上述开口还可以包括两个第一角部和两个其他角部，每个第一角部和一个相应的其他角部相对，此时两个角部为相邻的角部，根据该两个角部的相对位置关系而将其中一个角部作为判定不同类型开口的基准角部，以该基准角部指向与其相对的角部的方向作为基准方向；上述开口还可以包括三个角部和一个其他角部，以与该其他角 部相对的角部为基准角部来判定不同类型开口，并以该基准角部指向与其相对的角部的方向作为基准方向。
例如，图7为图2所示一个开口的放大图。如图2和图7所示，在至少一个开口210中，除上述基准第一角部1011和与其相对的角部外的其他两个角部的顶点的连线L将该开口210分为两个部分，一个部分为第一角部1011所在的部分，另一个部分为与第一角部1011相对的角部1012(例如为第二角部1012)所在的部分。例如，第一角部1011所在部分的面积与第二角部1012所在部分的面积之比可以为0.1～0.99。例如，第一角部1011所在部分的面积与第二角部1012所在部分的面积之比可以为0.2～0.9。例如，第一角部1011所在部分的面积与第二角部1012所在部分的面积之比可以为0.3～0.8。例如，第一角部1011所在部分的面积与第二角部1012所在部分的面积之比可以为0.4～0.7。
例如，如图7所示，第一角部1011的顶点与连线L之间的距离d1小于第二角部1012的顶点与连线L之间的距离d2。例如第一角部1011的顶点和连线L之间的距离d1与第二角部1012的顶点与连线L之间的距离d2之比d1/d2的范围可以为0.1～0.9。例如，d1/d2的范围可以为0.2～0.8。例如，d1/d2的范围可以为0.4～0.6。例如，d1与d2之比的范围可以为0.7～0.9。
例如，如图7所示，第一角部1011的顶点与第二角部1012的顶点之间的连线的长度可以为a(即上述距离d1与距离d2之和)，连线L的长度可以为b，a与b之比的范围可以为0.6～0.9。例如，a与b之比的范围可以为0.7～0.8。
例如，如图2所示，由于第一角部1011的朝向可以包括向上、向下、向左、向右、斜向左上，斜向左下，斜向右上，或者斜向右下，第一角部1011的顶点指向与其相对的角部的顶点的方向也可以包括多个方向，例如至少两种类型开口210中，第一角部1011的顶点指向与其相对的角部的顶点的方向可以包括方向D1、方向D2、方向D3和方向D4的至少两个，且各个方向不同。例如，两种类型开口210的第一角部1011的顶点指向与其相对的角部的顶点的方向可以平行且相反，也可以相交。
例如，如图1至图4A所示，多个隔垫物300中的至少部分分布在同一类型开口对应的间隔处。例如，分布在同一类型开口对应的间隔处的隔垫物300均匀分布，有利于降低隔垫物的制作工艺难度。
例如，如图2所示，至少两种类型开口210包括第一类型开口1001、第二类型开口1002、第三类型开口1003和第四类型开口1004的至少两种。例如， 如图2所示，第一类型开口1001中第一角部1011的顶点指向与其相对的角部的顶点的方向可以为方向D2，第二类型开口1002中第一角部1011的顶点指向与其相对的角部的顶点的方向可以为方向D3，第三类型开口1003中第一角部1011的顶点指向与其相对的角部的顶点的方向可以为方向D4，第四类型开口1004中第一角部1011的顶点指向与其相对的角部的顶点的方向可以为方向D1。例如，多个隔垫物300中的至少部分可以均匀的分布在第一类型开口1001对应的间隔处；或者，多个隔垫物300中的至少部分可以均匀的分布在第二类型开口1002对应的间隔处；或者，多个隔垫物300中的至少部分可以均匀的分布在第三类型开口1003对应的间隔处；或者，多个隔垫物300中的至少部分可以均匀的分布在第四类型开口1004对应的间隔处。
例如，如图2所示，第一类型开口1001、第二类型开口1002、第三类型开口1003以及第四类型开口1004中的两种类型开口中的第一角部1011的朝向相反，另外两种类型开口中的第一角部1011的朝向相反。例如，第四类型开口1004的方向D1与第三类型开口1003的方向D4相反，则第四类型开口1004的第一角部1011的朝向与第三类型开口1003的第一角部1011的朝向相反。例如，第一类型开口1001的方向D2与第二类型开口1002的方向D3相反，则第一类型开口1001的第一角部1011的朝向与第二类型开口1002的第一角部1011的朝向相反。本公开实施例对上述四种类型开口的名称不作限制，上述“第一类型开口”、“第二类型开口”、“第三类型开口”以及“第四类型开口”的名称可以互换。
例如，图8A为根据本公开实施例的另一示例提供的像素限定层以及隔垫物的平面结构示意图。如图8A所示，多个隔垫物300包括多个第一隔垫物310，多个第一隔垫物310分布在同一类型开口的第一角部1011对应的间隔处，且多个第一隔垫物310均匀分布。
例如，图8A示意性的示出多个第一隔垫物310分布在至少部分第一类型开口1001的第一角部1011对应的间隔处，但不限于此，还可以分布在其他类型开口(如第二类型开口1002、第三类型开口1003或者第四类型开口1004)的第一角部1011对应的间隔处。当然，本公开实施例不限于第一隔垫物分布在同一类型开口的角部对应的间隔处，例如第一隔垫物的一部分可以分布在一种类型开口的角部对应的间隔处，第一隔垫物的另一部分可以分布在其他类型开口中的至少一种开口的角部对应的间隔处，第一隔垫物可以规律设置即可。
例如，如图8A所示，多个隔垫物300还包括多个第二隔垫物320，多个第二隔垫物320分布在至少部分第二类型开口1002的第一角部1011对应的间隔处，且多个第二隔垫物320均匀分布。本公开实施例示意性的示出第二类型开口1002为第一角部1011朝向左的开口，但不限于此，第二类型开口还可以为角部朝向上、向下或者向右中的一种类型开口，本公开实施例对此不作限制。
例如，如图8A所示，第一隔垫物310和第二隔垫物320可以均为长条形，则两者的长条形的长边可以平行，也可以相交，本公开实施例对此不作限制。
例如，第一隔垫物310与第二隔垫物320的数量可以相同，也可以不同。例如，两者的数量比(可以指第一隔垫物310的数量与第二隔垫物320的数量的比值，也可以指第二隔垫物320的数量与第一隔垫物310的数量的比值)可以为0.1～1，或者0.2～0.9，或者0.3～0.8，或者0.4～0.7，或者0.5～0.6。
例如，如图2和图8A所示，与一个开口210相邻的隔垫物300的数量可以为一个，也可以为两个。例如，在与一个开口210相邻的隔垫物300的数量为两个时，这两个隔垫物300可以位于开口210的相邻的两个角部对应的间隔处，也可以位于开口210的相对的两个角部对应的间隔处，本公开实施例对此不作限制。
本公开实施例不限于此，例如，与一个开口相邻的隔垫物的数量还可以为三个或者四个，可以根据实际产品需求进行设置。
本公开实施例不限于隔垫物仅包括第一隔垫物和第二隔垫物，例如，隔垫物还可以包括第三隔垫物，第三隔垫物可以分布在第三类型开口或第四类型开口的第一角部对应的间隔处，例如第三隔垫物可以均匀分布；例如，隔垫物还可以包括第四隔垫物，第四隔垫物可以分布在剩下的一种类型开口的第一角部对应的间隔处，例如第四隔垫物可以均匀分布。
例如，隔垫物可以任意分布在设置第一角部对应的间隔处，且规律性的分布。这里规律性的分布可以指隔垫物在行方向上基本等间距的分布，例如任意相邻两个隔垫物之间设置有四个开口(不限于四个开口，还可以是两个、六个等)；隔垫物在列方向上也是基本等间距的分布，例如任意相邻两个隔垫物之间设置有四个开口(不限于四个开口，还可以是两个、六个等)。
例如，第一隔垫物310和第二隔垫物320的形状和大小可以相同，也可以不同。图8A示意性的示出第一隔垫物310的形状与第二隔垫物320的形状和大小均相同，即所有隔垫物300的形状和大小均相同。本公开实施例中，隔垫 物的形状可以指隔垫物在衬底基板上的正投影的形状，隔垫物的大小可以指隔垫物在衬底基板上的正投影的面积。
例如，图8B为根据本公开实施例的另一示例提供的像素限定层以及隔垫物的平面结构示意图。图8B所示示例与图8A所示示例不同之处在于至少部分隔垫物的大小不同。例如，第一隔垫物310和第二隔垫物320的形状不同，大小也不同。例如，第一隔垫物310和第二隔垫物320的形状相同，大小不同。
例如，隔垫物300可以包括沿任一方向上的最大尺寸，该最大尺寸的延伸方向不同的隔垫物的面积不同。例如，位于第一角部1011对应的间隔处的隔垫物300的面积不同于位于非第一角部对应的间隔处的隔垫物的面积。
本公开实施例对第一隔垫物和第二隔垫物的形状不作限制，例如第一隔垫物和第二隔垫物的形状还可以为圆形、椭圆形、菱形、正方形等规则形状，也可以为不规则形状，可以根据实际产品需要进行设置。
图8C为显示基板的平面示意图。如图2、图8A至图8C所示，所述显示基板包括显示区AA以及围绕显示区AA的非显示区NA。图2和图3示出了显示区的部分区域。例如，所述多个子像素100位于显示区AA，所述多个隔垫物300的至少部分位于所述显示区AA。例如，显示区AA内的隔垫物300可以包括位于所述第一角部1011和与该第一角部1011相邻的开口210之间的间隔处的所述隔垫物以及位于其他位置的隔垫物，位于所述第一角部1011和与该第一角部1011相邻的开口210之间的间隔处的所述隔垫物300的数量与位于所述显示区AA的所述隔垫物300的数量比例不小于50％。
例如，位于所述第一角部1011和与该第一角部1011相邻的开口210之间的间隔处的所述隔垫物300的数量与位于所述显示区AA的所述隔垫物300的数量比例不小于60％。例如，位于所述第一角部1011和与该第一角部1011相邻的开口210之间的间隔处的所述隔垫物300的数量与位于所述显示区AA的所述隔垫物300的数量比例不小于70％。例如，位于所述第一角部1011和与该第一角部1011相邻的开口210之间的间隔处的所述隔垫物300的数量与位于所述显示区AA的所述隔垫物300的数量比例不小于80％。例如，位于所述第一角部1011和与该第一角部1011相邻的开口210之间的间隔处的所述隔垫物300的数量与位于所述显示区AA的所述隔垫物300的数量比例不小于90％。
例如，如图2和图8A所示，开口210包括被配置为限定不同颜色子像素的开口，例如在行方向、列方向或者斜向方向的至少之一的方向上，相邻的两 个开口210被配置为限定不同颜色子像素的发光区。例如，被配置为限定不同颜色子像素的开口可以包括第一开口211、第二开口212和第三开口213，第一开口211、第二开口212和第三开口213之一用于限定红色子像素的发光区，另一个用于限定蓝色子像素的发光区，剩余的开口用于限定绿色子像素的发光区。
例如，如图2和图8A所示，至少部分隔垫物300分布在被配置为限定不同颜色子像素的开口210的第一角部1011和与该第一角部1011相邻的开口210之间的间隔处。例如，隔垫物300可以分布在第三开口213的第一角部1011和第一开口211之间的间隔处。
例如，隔垫物300也可以分布在限定同一种颜色子像素的两个开口210之间，例如，隔垫物300分布在两个第二开口211之间，第二开口211朝向隔垫物300的角部可以为第一角部，也可以不是，本公开实施例对此不作限制。
例如，图9为根据本公开实施例的另一示例提供的像素限定层以及隔垫物的平面结构示意图。如图9所示，与至少一个隔垫物300紧邻的至少两个开口210均包括第一角部1011，且至少两个开口210的第一角部1011均朝向该隔垫物300。
例如，如图9所示，第一开口211和第三开口213均包括第一角部1011，且两个开口210的第一角部1011均朝向位于两个开口210之间的隔垫物300，以进一步增加位于隔垫物两侧的两个开口的彼此相对的角部之间的距离，从而，既可以仅增加隔垫物的尺寸，又可以仅增加隔垫物与开口之间的距离，还可以隔垫物的尺寸以及隔垫物与开口之间的距离均增加，可以降低隔垫物脱落的几率，有利于提升产品的工艺良率与隔垫物的支撑作用。
本公开实施例不限于与隔垫物300紧邻的至少两个开口210(图9所示的第一开口211和第三开口213)均包括第一角部1011，且两个开口210的第一角部1011均朝向该隔垫物300。例如，与隔垫物300紧邻的三个开口，例如包括第一开口211、第三开口213以及一个第二开口212，均包括第一角部1011，且三个开口210的第一角部1011均朝向该隔垫物300。例如，与隔垫物300紧邻的三个开口210，例如包括两个第二开口212以及一个第一开口211或者一个第三开口213，均包括角部，且三个开口210的第一角部1011均朝向该隔垫物400。例如，与隔垫物300紧邻的四个开口，例如包括第一开口211、第三开口213以及两个第二开口212，均包括第一角部1011，且四个开口210的 第一角部1011均朝向该隔垫物300。
例如，如图1至图9所示，显示基板包括多个子像素100。如图1所示，多个子像素100包括多个第一颜色子像素110、多个第二颜色子像素120以及多个第三颜色子像素130。多个第一颜色子像素110和多个第三颜色子像素130沿行方向(如图1所示的X方向)交替设置以形成第一像素行01，多个第二颜色子像素120沿行方向排列以形成第二像素行02，第一像素行01和第二像素行02沿与行方向交叉的列方向(如图1所示的Y方向)交替设置且在行方向上彼此错开。例如，相邻的第一颜色子像素110和第二颜色子像素120沿第一方向排列，第一方向与行方向和列方向均相交。如图1所示，多个第一颜色子像素110和多个第三颜色子像素130沿列方向交替设置以形成多个第一像素列03，多个第二颜色子像素120沿行方向和列方向均阵列排布以形成多个第二像素行02和多个第二像素列04，多个第一像素列03和多个第二像素列04沿行方向交替设置且在列方向上彼此错开，即一个第二颜色子像素120所在第二像素行02位于相邻两个第一像素行01之间，且该第二颜色子像素120所在第二像素列04位于相邻两个第一像素列03之间。
本公开实施例中，行方向和列方向均指第一颜色子像素和第三颜色子像素的排列方向，该方向可能与相邻两个子像素的发光区的几何中心连线方向平行，也可能不平行。例如，行方向与列方向相交。例如，行方向与列方向之间的夹角可以为80-100度。例如，行方向与列方向之间的夹角可以为85-95度。例如，行方向和列方向可以垂直，但不限于此，也可以不垂直。本公开实施例中，行方向和列方向可以互换。
本公开实施例中的子像素指发光器件结构，第一颜色子像素、第二颜色子像素和第三颜色子像素为发出不同颜色光的子像素。本公开实施例以第一颜色子像素为红色子像素，第二颜色子像素为绿色子像素，第三颜色子像素为蓝色子像素为例进行说明。但第一颜色子像素为红色子像素，第二颜色子像素为绿色子像素以及第三颜色子像素为蓝色子像素并不构成对本公开实施例保护范围的限制。
例如，至少一个蓝色子像素的发光区的面积大于至少一个红色子像素的发光区的面积，至少一个红色子像素的发光区的面积大于至少一个绿色子像素的发光区的面积，以延长显示基板的使用寿命。例如，相同颜色子像素的发光区的面积基本相等。
例如，如图1至图9所示，像素限定层200的多个开口210包括多个第一开口211、多个第二开口212以及多个第三开口213，多个第一开口211被配置为限定多个第一颜色子像素110的发光区101，多个第二开口212被配置限定多个第二颜色子像素120的发光区101，多个第三开口213被配置为限定多个第三颜色子像素130的发光区101。
例如，如图1至图9所示，第一开口211、第二开口212和第三开口213的至少一种开口210包括第一角部1011。
例如，图2示意性的示出仅第三开口213包括第一角部1011，图9示意性的示出第一开口211和第三开口213均包括第一角部1011，本公开实施例不限于此。例如，第一开口、第二开口以及第三开口均包括第一角部，或者第一开口和第二开口包括第一角部，或者第二开口和第三开口包括第一角部，或者仅第一开口包括第一角部，或者仅第二开口包括第一角部。
例如，如图2、图6以及图8A所示，多个隔垫物300的至少部分分布在沿列方向和行方向的至少之一排布的相邻两个开口210之间的间隔处。
例如，隔垫物300可以分布在行方向排列的两个第二开口212之间，且分布在列方向排列的第一开口211和第三开口213之间。例如，隔垫物300可以分布在列方向排列的两个第二开口212之间，且分布在行方向排列的第一开口211和第三开口213之间。例如，围绕隔垫物300的开口210可以包括一个第一开口211、一个第三开口213以及两个第二开口212，第一开口211和第三开口213可以沿行方向和列方向之一排列，两个第二开口212可以沿行方向和列方向的另一个方向排列。同理，围绕隔垫物300的子像素100可以包括一个第一颜色子像素110、一个第三颜色子像素130以及两个第二颜色子像素120，第一颜色子像素110和第三颜色子像素130可以沿行方向和列方向之一排列，两个第二颜色子像素120可以沿行方向和列方向的另一个方向排列。
例如，如图1和图2所示，沿行方向和列方向之一，相邻隔垫物300之间设置有四个第二颜色子像素120，沿行方向和列方向的另一个，相邻隔垫物300之间设置有两个第一颜色子像素110以及两个第三颜色子像素130。例如，沿行方向和列方向之一，相邻隔垫物300之间设置有四个第二开口212，沿行方向和列方向的另一个，相邻隔垫物300之间设置有两个第一开口211以及两个第三开口213。
例如，图10A为根据本公开实施例的另一示例提供的像素限定层以及隔垫 物的平面结构示意图。如图1和图10A所示，沿行方向和列方向之一，相邻隔垫物300之间设置有六个第二颜色子像素120，沿行方向和列方向的另一个，相邻隔垫物300之间设置有三个第一颜色子像素110以及三个第三颜色子像素130。例如，沿行方向和列方向之一，相邻隔垫物300之间设置有六个第二开口212，沿行方向和列方向的另一个，相邻隔垫物300之间设置有三个第一开口211以及三个第三开口213。图中示意性的示出，部分隔垫物300位于第一角部1011对应的间隔处，部分隔垫物300没有位于第一角部1011对应的间隔处，本公开实施例不限于此。例如，可以通过调整开口的第一角部的朝向，使得所有隔垫物均位于第一角部对应的间隔处，例如，将所有第三开口213的第一角部1011的朝向均调整为朝下，以使的所有隔垫物均位于第一角部1011对应的间隔处。例如，还可以将所有第一开口211的第一角部1011的朝向均调整为朝上，以使的所有隔垫物均位于第一角部1011对应的间隔处。例如，还可以在第二开口212中设置朝向右或者朝向左的第一角部1011，以使的所有隔垫物均位于第一角部1011对应的间隔处。
例如，图10B为根据本公开实施例的另一示例提供的像素限定层以及隔垫物的平面结构示意图。如图1和图10B所示，沿行方向和列方向之一，相邻隔垫物300之间设置有六个第二颜色子像素120，沿行方向和列方向的另一个，相邻隔垫物300之间设置有两个第一颜色子像素110以及两个第三颜色子像素130。例如，沿行方向和列方向之一，相邻隔垫物300之间设置有六个第二开口212，沿行方向和列方向的另一个，相邻隔垫物300之间设置有两个第一开口211以及两个第三开口213。图中示意性的示出，部分隔垫物300位于第一角部1011对应的间隔处，部分隔垫物300没有位于第一角部1011对应的间隔处，本公开实施例不限于此。例如，可以通过调整开口的第一角部的朝向，使得所有隔垫物均位于第一角部对应的间隔处，例如，将所有第三开口213的第一角部1011的朝向均调整为朝下，以使的所有隔垫物300均位于第一角部1011对应的间隔处。例如，还可以将所有第一开口211的第一角部1011的朝向均调整为朝上，以使的所有隔垫物300均位于第一角部1011对应的间隔处。例如，还可以在第二开口212中设置朝向右或者朝向左的第一角部1011，以使的所有隔垫物300均位于第一角部1011对应的间隔处。
例如，图10C为根据本公开实施例的另一示例提供的像素限定层以及隔垫物的平面结构示意图。如图1和图10C所示，沿行方向和列方向之一，相邻隔 垫物300之间设置有四个第二颜色子像素120，沿行方向和列方向的另一个，相邻隔垫物300之间设置有三个第一颜色子像素110以及三个第三颜色子像素130。例如，沿行方向和列方向之一，相邻隔垫物300之间设置有四个第二开口212，沿行方向和列方向的另一个，相邻隔垫物300之间设置有三个第一开口211以及三个第三开口213。图中示意性的示出，部分隔垫物300位于第一角部1011对应的间隔处，部分隔垫物300没有位于第一角部1011对应的间隔处，本公开实施例不限于此。例如，可以通过调整开口的第一角部的朝向，使得所有隔垫物均位于第一角部对应的间隔处，例如，将所有第三开口213的第一角部1011的朝向均调整为朝下，以使的所有隔垫物300均位于第一角部1011对应的间隔处。例如，还可以将所有第一开口211的第一角部1011的朝向均调整为朝上，以使的所有隔垫物300均位于第一角部1011对应的间隔处。例如，还可以在第二开口212中设置朝向右或者朝向左的第一角部1011，以使的所有隔垫物300均位于第一角部1011对应的间隔处。
例如，如图1和图8A所示，具有第一角部1011且被配置为限定同一种颜色子像素100的发光区101的开口210包括至少两种类型开口，不同类型开口中，第一角部1011的顶点指向与其相对的角部的顶点的方向不同，多个隔垫物300包括多个第一隔垫物310和多个第二隔垫物320，第一隔垫物310和第二隔垫物320分布在不同类型开口的第一角部1011对应的间隔处。
例如，如图1和图8A所示，沿行方向和列方向之一，相邻第一隔垫物310之间设置有四个第二颜色子像素120，沿行方向和列方向的另一个，相邻第一隔垫物310之间设置有两个第一颜色子像素110以及两个第三颜色子像素130；沿行方向和列方向之一，相邻第二隔垫物320之间设置有四个第二颜色子像素120，沿行方向和列方向的另一个，相邻第二隔垫物320之间设置有两个第一颜色子像素110以及两个第三颜色子像素130。例如，沿行方向和列方向之一，相邻第一隔垫物310之间设置有四个第二开口212，沿行方向和列方向的另一个，相邻第一隔垫物310之间设置有两个第一开口211以及两个第三开口213；沿行方向和列方向之一，相邻第二隔垫物320之间设置有四个第二开口212，沿行方向和列方向的另一个，相邻第二隔垫物320之间设置有两个第一开口211以及两个第三开口213。
例如，如图1和图2所示，至少部分第三开口213包括第一角部1011，各隔垫物300设置在第三开口213的第一角部1011和与其相邻的第一开口211 之间的间隔处。
例如，如图5B所示，隔垫物300与位于其一侧第三开口213中的第一角部1011之间的距离为第一距离S1，隔垫物300与位于其另一侧的第一开口211的角部的最短距离为第二距离S2，第一距离S1不小于第二距离S2。这里第一距离S1与第二距离S2之间的关系，以及与图5C所示的距离S0之间的大小关系如前文所述，在此不再赘述。
例如，图5B仅示意性的示出第三开口213包括第一角部1011时，隔垫物300与开口210之间距离的关系与图5A所示没有设置第一角部时隔垫物030与开口021之间距离关系的比较，本公开实施例不限于此。例如，还可以如图9所示第一开口211和第三开口213的彼此相对的角部均为第一角部1011，隔垫物300位于这两个第一角部1011之间。例如，还可以第一开口和第三开口除彼此相对的角部外的其他至少部分角部也设置成第一角部。例如，还可以行方向或列方向排列的相邻两个第二开口彼此相对的角部的至少之一设置为第一角部1011，隔垫物300位于这两个第一角部之间。
在除图5B、图5C以及图9所示示例以外的其他示例中，通过在至少一个开口(可以为第一开口、第二开口以及第三开口的任一、任两个以及三个)设置第一角部，调节隔垫物与开口的第一角部之间的距离以增加隔垫物与位于其两侧的两个开口之间的距离，有利于降低隔垫物脱落的几率，以提高工艺良率。
例如，如图9所示，沿行方向和列方向至少之一的方向彼此相邻的两个开口210均包括第一角部1011，且两个开口210中的第一角部1011彼此相对。本公开实施例示意性的示出这两个开口可以为第一开口211和第三开口213，但是不限于此，这两个开口也可以为两个第二开口212。
例如，如图1和图2所示，被配置为限定沿行方向(或列方向)排列的相同颜色的子像素100的发光区101的开口210中第一角部1011的朝向不同，则位于同一行(或同一列)的相同颜色子像素100的发光区101的几何中心连线C1不是直线，例如为一条折线。
例如，被配置为限定第三颜色子像素130的发光区101的开口210包括第一角部1011，被配置为限定第一颜色子像素110的发光区101的开口210不包括第一角部，则位于同一行(或同一列)的多个第一颜色子像素110和多个第三颜色子像素130的发光区的几何中心的连线不是直线，例如为一条折线。
例如，图11A为根据本公开实施例的另一示例提供的像素限定层以及隔垫 物的平面结构示意图。如图11A所示，至少部分开口210包括至少两个第一角部1011。例如，第一开口211包括四个第一角部1011，第二开口212包括两个第一角部1011，第三开口213包括一个第一角部1011。本公开实施例不限于此，还可以第一开口包括至少两个第一角部。
例如，如图11A所示，围绕隔垫物300的四个开口210均包括第一角部1011，且各开口210中最靠近隔垫物300的角部均为第一角部1011，从而可以在两个方向上均增加隔垫物的尺寸，和/或，在两个方向上均增加隔垫物与开口之间的距离，有利于降低隔垫物脱落的几率，提升产品的工艺良率与隔垫物的支撑作用。
例如，如图11A所示，第一开口211、第二开口212和第三开口213均包括第一角部1011，且第一开口211、第二开口212和第三开口213的至少两种开口210包括的第一角部1011的数量不同。
例如，至少部分开口210包括四个角部，第一开口211、第二开口212以及第三开口210的四个角部包括两个、三个或四个第一角部1011，第一开口211、第二开口212以及第三开口213的另外两个开口210的至少之一的四个角部包括一个第一角部1011。
例如，在各开口的角部的数量为四个时，本公开实施例对被配置为限定不同颜色子像素的发光区的开口包括的第一角部的数量不作限制，可以被配置为限定三种颜色子像素的发光区的开口包括的第一角部的数量均不相同，该数量可以从1-4中选择3个；也可以是被配置为限定两种颜色子像素的发光区的两种开口包括的第一角部的数量相同，第三种开口包括的角部的数量不同，则两种开口包括的第一角部的数量可以从1-4中选择1个，第三种开口包括的第一角部的数量可以从1-4中选择另一个；也可以是被配置为限定仅两种颜色子像素的发光区的两个开口包括第一角部，则不同开口包括的第一角部的数量可以从1-4中选择2个，本公开实施例可以根据产品的需要进行设置。
当然，本公开实施例不限于各开口的第一角部的数量为四个，还可以为三个或大于四个，此时，开口中的第一角部的数量可以按照上述规律进行设置。
需要说明的是，本公开实施例的示意性的示出像素限定层的开口包括的角部中除了第一角部1011以外的其他角部均为两条直边相交形成的直角或者锐角，但是不限于此，除了第一角部1011以外的其他角部的至少部分还可以为圆倒角(第二角部)，该第二角部可以为多边形被截去由两条边所夹的角部后 形成的角部，两条边至少之一被截去的部分与该边之比为0.05～0.2。这里第二角部的定义方式可以与第一角部1011的定义方式相同，但是第二角部的曲率(或圆弧弧度或长度)小于第一角部1011的曲率(或圆弧弧度或长度)。
图11B为部分子像素的发光层与相应开口对应关系示意图。如图11B所示，同一种颜色的子像素的发光层1300的形状和尺寸相同，图中示意性的示出第三颜色子像素的发光层，第三颜色子像素的发光层的形状和尺寸均相同。例如，其他颜色子像素，如第一颜色子像素的发光层的形状和尺寸均相同，如第一颜色子像素的发光层的形状和尺寸均相同。
例如，如图11B所示，所述发光层1300包括位于开口210内的部分以及位于像素限定层2000上的另一部分，发光层1300在所述像素限定层200上的部分具有边界，该边界和与该发光层1300对应的所述第一角部1011的距离S5不同于该边界和与该发光层1300对应的其他角部之间的距离S6。
例如，发光层1300的边界与该发光层1300对应的开口210的第一角部的距离S5大于该边界和与该发光层1300对应的其他角部之间的距离S6。例如，该边界和与该发光层1300对应的其他角部之间的距离S6可以均相等。例如，距离S5与距离S6的比值范围可以为1.1～10。例如，距离S5与距离S6的比值范围可以为1.2～7。例如，距离S5与距离S6的比值范围可以为1.3～5。例如，距离S5与距离S6的比值范围可以为1.4～3。例如，距离S5与距离S6的比值范围可以为1.5～2。例如，距离S5与距离S6的比值范围可以为1.6～1.8。
例如，如图11B所示，被配置为限定同种颜色子像素的发光区的开口210的第一角部1011的朝向不同，但形成在限定同种颜色子像素的发光区的开口210内发光层1300可以具有基本相同的形状和尺寸。
例如，各子像素还包括像素电路，像素电路被配置为与发光元件连接以驱动发光元件发光。例如，图12为像素电路的等效图。如图12所示，像素电路2000包括第二复位晶体管T1、第二发光控制晶体管T5、第一发光控制晶体管T6、数据写入晶体管T4、驱动晶体管T3、阈值补偿晶体管T2、第一复位控制晶体管T7以及存储电容C。例如，显示基板还包括复位电源信号线、扫描信号线、电源信号线、复位控制信号线、发光控制信号线以及数据线。

例如，如图13所示，有源半导体层3100可采用半导体材料图案化形成。有源半导体层3100可用于制作上述的第二复位晶体管T1、阈值补偿晶体管T2、驱动晶体管T3、数据写入晶体管T4、第二发光控制晶体管T5、第一发光控制晶体管T6和第一复位控制晶体管T7的有源层。有源半导体层3100包括各子像素的各晶体管的有源层图案(沟道区)和掺杂区图案(源漏掺杂区)，且同一像素电路中的各晶体管的有源层图案和掺杂区图案一体设置。
需要说明的是，有源层可以包括一体形成的低温多晶硅层，源极区域和漏极区域可以通过掺杂等进行导体化以实现各结构的电连接。也就是每个子像素的各晶体管的有源半导体层为由p-硅形成的整体图案，且同一像素电路中的各晶体管包括掺杂区图案(即源极区域和漏极区域)和有源层图案，不同晶体管的有源层之间由掺杂结构隔开。
例如，有源半导体层3100可采用非晶硅、多晶硅、氧化物半导体材料等制作。需要说明的是，上述的源极区域和漏极区域可为掺杂有n型杂质或p型杂质的区域。
图13中各虚线矩形框示出了第一导电层3200与有源半导体层3100交叠的各个部分。作为各个晶体管的沟道区(即上述有源层图案)，在每个沟道区两侧的有源半导体层通过离子掺杂等工艺导体化作为各个晶体管的第一极和第二极(即上述掺杂区图案)。晶体管的源极、漏极在结构上可以是对称的，所以其源极、漏极在物理结构上可以是没有区别的。在本公开的实施例中，为了区分晶体管，除作为控制极的栅极，直接描述了其中一极为第一极，另一极为第二极，所以本公开的实施例中全部或部分晶体管的第一极和第二极根据需要是可以互换的。
例如，显示基板包括位于有源半导体层远离衬底基板一侧的栅极绝缘层，用于将上述的有源半导体层3100与后续形成的第一导电层3200(即栅极金属层)绝缘。图14示出了该显示基板包括的第一导电层3200，第一导电层3200设置在栅极绝缘层上，从而与有源半导体层3100绝缘。第一导电层3200可以包括电容C的第二极CC2、沿X方向延伸的多条扫描信号线043、多条复位控制信号线044、多条发光控制信号线045以及第二复位晶体管T1、阈值补偿晶体管T2、驱动晶体管T3、数据写入晶体管T4、第二发光控制晶体管T5、第一发光控制晶体管T6和第一复位控制晶体管T7的栅极。

例如，在上述的第一导电层3200上形成有第一绝缘层，用于将上述的第一导电层3200与后续形成的第二导电层3300绝缘。
例如，如图13至图15所示，第二导电层3300包括电容C的第一极CC1以及沿X方向延伸多条复位电源信号线041。电容C的第一极CC1与电容C的第二极CC2至少部分重叠以形成电容C。

例如，在上述的第而导电层3300上形成有第二绝缘层，用于将上述的第二导电层3300与后续形成的源漏金属层3400绝缘。
例如，如图16所示，源漏金属层3400包括沿Y方向延伸的数据线910以及电源信号线920。数据线910通过贯穿栅极绝缘层、第一绝缘层和第二绝缘层的过孔与数据写入晶体管T2的第二极电连接。电源信号线920通过贯穿栅极绝缘层、第一绝缘层和第二绝缘层的过孔与第二发光控制晶体管T5的第一极电连接。电源信号线920和数据线910沿X方向交替设置。电源信号线920通过贯穿第二绝缘层的过孔与电容C的第一极CC1电连接。

例如，如图16所示，各像素电路还包括：与数据线910同层设置的连接部052和连接部053，连接部052被配置为连接阈值补偿晶体管T2的第二极和驱动晶体管T3的栅极，连接部053被配置为连接第一复位控制晶体管T7的第一极和复位电源信号线041。例如，连接部052的一端通过贯穿栅极绝缘层、第一绝缘层和第二绝缘层中的过孔与阈值补偿晶体管T2的第二极电连接，连接部052的另一端通过贯穿第一绝缘层和第二绝缘层中的过孔与驱动晶体管T3的栅极(即电容C的第二极CC2)电连接。连接部053的一端通过贯穿第二绝缘层中的过孔与复位电源信号线041电连接，第三连接部053的另一端通 过贯穿栅极绝缘层、第一绝缘层和第二绝缘层中的过孔与第一复位控制晶体管T7的第一极电连接。
例如，如图16所示，各像素电路还包括与数据线910同层设置的连接部055，连接部055用于连接发光元件的第二电极与第一复位控制晶体管T7的第二极。
例如，如图2-3和图17所示，各子像素100的第二电极1200包括主体电极1201，至少部分第二电极1200的主体电极1201的形状可以与其发光区101或者其对应开口210的形状相同。例如，第一颜色子像素110的发光区101的形状为矩形，则其第二电极1210的主体电极的形状可以为矩形。
例如，主体电极1201的几何中心可以与其对应的发光区101的几何中心大致重合，或者两个几何中心之间的距离很小。
例如，像素限定层200的开口210在衬底基板10上的正投影位于相应的发光元件1000的第二电极1200的主体电极1201在衬底基板10上的正投影内。
例如，至少部分具有第一角部1011的开口210内对应的子像素100的主体电极1201具有与该开口210大致相同的形状。例如，被配置为限定第三颜色子像素130的发光区101的第三开口213包括第一角部1011，第三颜色子像素130的第二电极1230的主体电极1201也包括与第一角部1011的形状对应的角部2101。本公开实施例通过将具有第一角部的开口内对应的子像素的主体电极设置为具有与该开口大致相同的形状，可以在保证显示效果的同时，有利于提升第二电极所在显示区域的透过率，进而有利于屏下指纹识别或屏下摄像头技术的应用集成。
例如，如图17所示，各第二电极1200还包括连接电极1202。例如，连接电极1202可以与主体电极1201为一体结构，例如连接电极1202被配置为通过过孔与像素电路的晶体管连接。
