在一种实施例中，所述交叠色阻包括共有色阻和第四色阻，所述共有色阻的颜色与所述第一色阻的颜色相同，所述第四色阻的颜色与所述第二色阻的颜色相同。在设置交叠色阻时，可以在制备对应发光像素的色阻后，在非发光区域，通过形成共有色阻和第四色阻，使共有色阻与第一色阻的颜色相同，第四色阻的颜色与第二色阻的颜色相同，则可以在形成交叠色阻时，先形成第一色阻，并在图案化第一色阻时保留非发光区域的第一色阻，然后在图案化第二色阻时，保留非发光区域的第二色阻，从而形成共有色阻和第四色阻，降低工艺难度，使交叠色阻对非发光区域的光线进行阻挡，避免光线出现串扰，且由于交叠色阻和对应发光像素的色阻分开设置，不会受对应发光像素的色阻的颜色的限制，可以根据需求确定交叠色阻的颜色。
在一种实施例中，所述交叠色阻包括共有色阻和第五色阻，所述共有色阻的颜色与所述第一色阻的颜色相同，所述第五色阻的颜色与所述第三色阻的颜色相同。在设置交叠色阻时，可以在制备对应发光像素的色阻后，在非发光区域，通过形成共有色阻和第五色阻，使共有色阻与第一色阻的颜色相同，第五色阻的颜色与第三色阻的颜色相同，则可以在形成交叠色阻时，先形成第一色阻，并在图案化第一色阻时保留非发光区域的第一色阻，然后在图案化第三色阻时，保留非发光区域的第三色阻，降低工艺难度，使交叠色阻对非发光区域的光线进行阻挡，避免光线出现串扰，且由于交叠色阻和对应发光像素的色阻分开设置，不会受对应发光像素的色阻的颜色的限制，可以根据需求确定交叠色阻的颜色。
在一种实施例中，所述交叠色阻包括共有色阻和第五色阻，所述共有色阻的颜色与所述第二色阻的颜色相同，所述第五色阻的颜色与所述第三色阻的颜色相同。在设置交叠色阻时，可以在制备对应发光像素的色阻后，在非发光区域，通过形成共有色阻和第五色阻，使共有色阻与第二色阻的颜色相同，第五色阻的颜色与第三色阻的颜色相同，则可以在形成交叠色阻时，先形成第二色阻，并在图案化第二色阻时保留非发光区域的第二色阻，然后在图案化第三色阻时，保留非发光区域的第三色阻，降低工艺难度，使交叠色阻对非发光区域的光线进行阻挡，避免光线出现串扰，且由于交叠色阻和对应发光像素的色阻分开设置，不会受对应发光像素的色阻的颜色的限制，可以根据需求确定交叠色阻的颜色。
在一种实施例中，所述交叠色阻包括第一交叠色阻和第二交叠色阻，所述第一交叠色阻包括共有色阻和第六色阻，所述第二交叠色阻包括共有色阻和第七色阻，所述共有色阻的颜色与所述第一色阻的颜色相同，所述第六色阻的颜色与所述第二色阻的颜色相同，所述第七色阻的颜色与所述第三色阻的颜色相同。在设置交叠色阻时，使第六色阻和第七色阻的颜色分别与第二色阻和第三色阻的颜色相同，使第一交叠色阻可以设置在与第二色阻相邻的非发光区域，使第二交叠色阻设置在与第三色阻相邻的非发光区域从而对非发光区域进行遮光，减少工艺步骤。
在一种实施例中，所述第一色阻为蓝色色阻、所述第二色阻为绿色色阻、所述第三色阻为红色色阻，通过使蓝色色阻为共有色阻，通过蓝色色阻和绿色色阻交叠设置、蓝色色阻与红色色阻交叠设置，从而对非发光区域进行遮光，避免出现混光导致显示效果较差，且无需设置黑色矩阵，减少工艺步骤。
针对色阻和交叠分开设置时，会导致工艺步骤较多，显示面板的制备效率较低的技术问题。在一种实施例中，所述第二色阻延伸至所述非发光区域形成第六色阻，所述第三色阻延伸至所述非发光区域形成第七色阻，所述共有色阻包括第一色阻延伸至所述非发光区域的部分和与所述第一色阻不连接的部分。通过在形成第一色阻、第二色阻时，使第一色阻和第二色阻延伸至非发光区域，则减少形成第一色阻、第二色阻、第六色阻和第七色阻的步骤，降低工艺难度，且在形成共有色阻和第三色阻时，可以通过图案化第一色阻得到对应发光像素的部分和共有色阻，减少工艺步骤，加快显示面板的制备效率。
在一种实施例中，所述共有色阻设置于所述第六色阻远离所述发光层的一侧，所述共有色阻设置于所述第七色阻远离所述发光层的一侧，即通过将共有色阻设置在外侧，使得在形成交叠色阻时，可以直接整层形成色阻后，图案化形成共有色阻的各个部分，减少工艺步骤。
具体的，在蓝色色阻形成共有色阻、红色色阻形成第六色阻、绿色色阻形成第七色阻时，将蓝色色阻设置于红色色阻远离所述发光层的一侧，且在所述绿色色阻与所述蓝色色阻形成交叠色阻的区域，所述蓝色色阻设置于所述绿色色阻远离所述发光层的一侧。在非发光区域将色阻交叠设置形成交叠色阻时，由于蓝色色阻的反射率相较于红色色阻的反射率和绿色色阻的反射率更低，通过将蓝色色阻设置在靠近入光的一侧，使光线在照射到蓝色色阻上时被吸收，从而降低显示面板的反射率。
针对非发光区域的色阻为交叠色阻，会导致非发光区域的厚度大于发光区域的厚度。在一种实施例中，在对应所述第二发光像素的区域，所述第二色阻上设有填充材料，在对应所述第三发光像素的区域，所述第三色阻上设有填充材料。通过在第二色阻上和第三色阻上设置填充材料，使得填充材料可以填平发光区域和非发光区域的高度差，便于后续膜层的设置。
具体的，如图2所示，以第一色阻251为红色色阻、第二色阻252为绿色色阻、第三色阻253为蓝色色阻、共有色阻的颜色与第三色阻的颜色相同为例，在第一发光区域281a，所述第一色阻251远离所述发光层23的一侧设有填充材料261，在所述第二发光区域281b，所述第二色阻252远离所述发光层23的一侧设有填充材料261。通过在第一发光区域和第二发光区域上设置填充材料，使得填充材料与蓝色色阻超出红色色阻和绿色色阻的厚度一致，从而使得彩膜层表面平坦，避免后续的膜层形成。
具体的，填充材料设置于所述红色色阻中与所述蓝色色阻未交叠的部分的一侧，且填充材料设置于所述绿色色阻中与所述蓝色色阻未交重叠的部分的一侧，通过在红色色阻和蓝色色阻未交叠的部分、绿色色阻和蓝色色阻未交叠的部分上设置填充材料，使得在低于蓝色色阻的厚度的区域对彩膜层进行填充，保证彩膜层能够平整，便于后续的膜层设置。
在一种实施例中，所述显示面板还包括光学胶层，所述光学胶层包括所述填充材料。由于光学胶具有较好的透光性，在对红色色阻和蓝色色阻未重叠的部分、绿色色阻和蓝色色阻未重叠的部分进行填充时，可以直接在形成光学胶时对红色色阻和蓝色色阻未重叠的部分、绿色色阻和蓝色色阻未重叠的部分进行填充，形成填充材料，减少了工艺流程，且光学胶的透光率较高，提高了显示面板的透光率。
在一种实施例中，所述第一色阻为绿色色阻、所述第二色阻为蓝色色阻、所述第三色阻为红色色阻，通过使绿色色阻为共有色阻，通过绿色色阻和蓝色色阻交叠设置、绿色色阻与红色色阻交叠设置，从而对非发光区域进行遮光，避免出现混光导致显示效果较差，且无需设置黑色矩阵，减少工艺步骤。
在一种实施例中，所述第一色阻为红色色阻、所述第二色阻为绿色色阻、所述第三色阻为蓝色色阻，通过使红色色阻为共有色阻，通过红色色阻和绿色色阻交叠设置、红色色阻与蓝色色阻交叠设置，从而对非发光区域进行遮光，避免出现混光导致显示效果较差，且无需设置黑色矩阵，减少工艺步骤。
针对红色色阻、绿色色阻和蓝色色阻交叠设置时，会出现非发光区域的厚度较大所导致的显示面板厚度较大的问题。在一种实施例中，在所述非发光区域，所述交叠色阻之间设有单色色阻，所述单色色阻与所述交叠色阻中的共有色阻的颜色相同。通过将交叠色阻分开设置，在交叠色阻之间设置单色色阻，且单色色阻的颜色与共有色阻的颜色相同，从而对非发光区域进行遮光的同时，降低显示面板的厚度。
具体的，如图2所示，以第一色阻251为红色色阻、第二色阻252为绿色色阻、第三色阻253为蓝色色阻、共有色阻的颜色与第三色阻的颜色相同为例，所述第一色阻251延伸至非发光区域的部分与第三色阻253形成第一交叠色阻，第二色阻252延伸至非发光区域的部分与第三色阻253形成第二交叠色阻，在第一交叠色阻和第二交叠色阻之间设有单色色阻，该单色色阻的颜色与共有色阻的颜色相同。通过将红色色阻和绿色色阻不接触设置，而通过将红色色阻和绿色色阻设置在同一层的不同部分，通过蓝色色阻填充至相邻交叠色阻之间，降低了显示面板的厚度，且由于蓝色色阻具有较低的反射率，进一步降低了显示面板的光线反射率。
具体的，如图2所示，所述单色色阻和共有色阻一体成型，即在形成单色色阻和共有色阻时，直接在第一色阻251和第二色阻252上形成第三色阻253，在图案化第三色阻253时，保留单色色阻和共有色阻，无需分别形成单色色阻和共有色阻，减少显示面板的工艺步骤。
上述实施例以共有色阻的颜色与第三色阻的颜色相同为例说明了单色色阻和交叠色阻的设置方式，在共有色阻的颜色与第一色阻的颜色相同、或者共有色阻的颜色与第二色阻的颜色相同时，也可采用上述设置方式，降低显示面板的厚度，并降低显示面板的光线反射率。
在一种实施例中，在所述非发光区域，所述交叠色阻相邻设置。即在设置交叠色阻时，例如交叠色阻中共有色阻为蓝色色阻，则可以将红色色阻和蓝色色阻设置在同一层，并使红色色阻和绿色色阻接触，然后在红色色阻和绿色色阻上形成蓝色色阻，则分别形成包括红色色阻和蓝色色阻的交叠色阻、包括绿色色阻和蓝色色阻的交叠色阻，使两个交叠色阻相邻设置，对非发光区域进行遮光，无需设置黑色矩阵，减少工艺步骤。
针对发光区域的各发光像素发出的光线的视角较大，仅将色阻设置在发光区域会导致部分光线损失的问题。如图2、图3所示，以第一色阻251为红色色阻、第二色阻252为绿色色阻、第三色阻253为蓝色色阻、共有色阻的颜色与第三色阻的颜色相同为例，所述第一色阻251设置于所述第一发光区域281a且延伸至所述非发光区域282，所述第三色阻253包括对应第三发光像素232c的蓝色偏光部分253a，所述蓝色偏光部分253a设置于所述第三发光区域281c且延伸至所述非发光区域282，所述第二色阻252设置于所述第一色阻251对应的区域、所述蓝色偏光部分253a对应的区域和所述单色色阻外的所有区域。通过将红色色阻从第一发光区域延伸至非发光区域，将蓝色色阻从第三发光区域延伸至非发光区域，将绿色色阻设置在红色色阻对应的区域、蓝色偏光部分对应的区域和单色色阻外的所有区域，使得各颜色的光线在大视角发射出去时，即使发射到非发光区域，由于非发光区域存在色阻，使得光线仍然能够以纯色发射出去，而通过将绿色色阻整面设置，降低了工艺难度，且在形成交叠色阻时，可以直接与对应发光像素的色阻同时形成，减少工艺步骤。
具体的，如图2所示，设置于非发光区域282的第一色阻251存在部分与所述第三色阻253不交叠，设置于非发光区域282的绿色色阻252存在部分与所述蓝色色阻253不交叠，在将红色色阻、绿色色阻和蓝色色阻设置在非显示区，以使大视角的光线能够通过对应颜色的色阻射出时，为了避免出现混光，使红色色阻、绿色色阻和蓝色色阻在非发光区域存在不交叠的部分，从而使各发光材料发出的光线保持纯色，提高显示效果。
具体的，如图2、图3所示，第一色阻251包括设置在红色无交叠区291a的第一部分251a和设置在红色有交叠区291b的第二部分，第三色阻253包括设置在蓝色无交叠区293a的蓝色偏光部分253a、设置在第一色阻251和第二色阻252之间的间隙对应的区域293b的单色色阻253b、设置在红色有交叠区291b的第一蓝色交叠部分和设置在绿色有交叠区292b的第二蓝色交叠部分（第一蓝色交叠部分和第二蓝色交叠部分为共有色阻的两个部分），第二色阻252包括设置在绿色无交叠区292a的第一部分252a和设置在绿色有交叠区292b的第二部分，在图3中，以标号31表示交叠设置的第一色阻的第二部分和第一蓝色交叠部分，以标号32表示交叠设置的第二色阻的第二部分和第二蓝色交叠部分。从图2、图3中可以看到，各个颜色的色阻均超出发光区域延伸至非发光区域，以使大视角射出的光线能够穿过对应颜色的色阻，且由于红色色阻和蓝色色阻之间的距离较大，将绿色色阻整面设置降低工艺难度，而通过在非发光区域使两层色阻交叠设置，降低了显示面板的厚度。
在一种实施例中，如图3所示，所述第一色阻的第一部分251a的宽度a为33.70微米，所述第一色阻的第二部分的宽度d为3.0微米，间隙中的单色色阻253b的宽度c为5.7微米，所述第二色阻的实轴长g为35.50、虚轴长f为26.70，所述第三色阻的蓝色偏光部分253a的宽度b为45.70微米，所述第一色阻的第一部分251a与第三色阻的蓝色偏光部分253a的距离e为24.7微米。
在一种实施例中，所述第一色阻的形状与所述第一发光像素的形状相同，且所述第一色阻在所述衬底上的投影围绕所述第一发光像素的投影对称设置。在设置红色色阻时，使红色色阻的形状与红色发光像素的形状相同，且使红色色阻的投影围绕红色发光像素的投影对称设置，使得红色色阻设置在非发光区域的部分环绕发光区域设置，则红色发光像素的大视角发出的光均能从红色色阻发射出去，且由于红色色阻的投影关于红色发光像素的投影对称设置，使得红色发光像素发出的光均匀发射出去，避免在某一侧的光线的强度大于其他方向的光线的强度，导致显示不均。
在一种实施例中，所述单色色阻的宽度大于所述发光像素的宽度，所述交叠色阻的宽度小于所述发光像素的宽度。通过使得单色色阻的宽度大于发光像素的宽度，使交叠色阻的宽度大于发光像素的宽度，则可以避免不同的发光区域出现混光，提高显示面板的显示效果。
