在所述阻挡区130，所述有机发光层107设于本发明的阻挡机构上，其由于阻挡机构的复杂结构使得所述有机发光层107分布参差不齐，有起有伏，并且在沟道140的有机发光层107是断开的，这可以有效的阻挡水氧在有机发光层107中的传递，进而可以保护显示区的功能器件。
所以说，本发明通过在通孔120周围设置一阻挡区130，在阻挡区130的基板101上形成沟道140以及在无机绝缘层102中形成阻挡块1021，该阻挡结构可以阻挡水氧传递至显示区110的有机发光层107。
其中，在蒸镀有机发光层107的时候，并没有在本发明的沟道内部形成连续的有机发光层107，所述有机发光层107在沟道140是断开的，并且在沟道140底部具有部分有机发光层1071。
所述封装层108设于所述有机发光层107上以及部分的所述沟道140上。具体的讲，所述封装层108正好将沟道140底部的所述有机发光层与所述阻挡块区上的有机发光层之间的断开区域填充，并且覆盖阻挡区域的有机发光层107，进而阻断可有机发光层107之间水氧传递，可以防止水氧从本发明的阻挡130区上方入侵显示区110的有机发光层107。
如图3所示，在阻挡区130与显示区110的连接处，还设有一挡墙109，所述挡墙109与所述显示区110之间设有沟道（图3标记1405），所述挡墙109设于靠近所述显示区110的阻挡块上。所述挡墙109通过曝光显影所述薄膜晶体管层103以及所述像素限定层105形成的挡墙109，可以有效的阻挡通孔的水汽。所述有机发光层107以及封装层109同样覆盖连接处的挡墙以及沟道（图3标记1205）。
所述阻挡块1021的材料包括氧化硅或氮化硅；所述基板101的材料为聚酰亚胺。
所述沟道140包括间断式沟道1402以及连续式沟道1401；所述连续式沟道1301以及所述间断式沟道1302交错分布并围绕所述通孔120。
本发明所述沟道包括三条连续式沟道（1401、1403、1045）以及两条间断式沟道（1402、1404）。
所述间断式沟道包括交替设置的第一部分以及第二部分；相邻的所述间断式沟道的第二部分相互对应，并且远离所述通孔的间断式沟道的第一部分长度大于靠近所述通孔的间断式沟道的第一部分长度。
具体的讲，所述间断式沟道（1402、1404）由多个第一部分（即细小沟道）交替形成，并且相邻的第一部分之间为第二部分（即为细小沟道之间的空隙），所述第二部分为阻挡区的基板未刻蚀的部分。
如图4所示，两条的间断式沟道1402以及1404，中间还设有一连续式沟道1403，其中，间断式沟道1402的第二部分1402a与间断式沟道1404的第二部分1404a相对应，并且间断式沟道1402的第一部分1402b的长度大于间断式沟道1404的第一部分1404b的长度。并且在间断式沟道1401的第一部分1402b与连续式沟道1403之间设有阻挡结构的所述阻挡块102，而在间断式沟道1402的第二部分1402b与所述连续式沟道1403之间并没有阻挡结构。
如图5所示，在另一实施例中，本发明的间断式沟道还可以直接相邻，中间并不设置连续式沟道，具体地，间断式沟道201的设于通孔120的外围，间断式沟道201的第二部分2012与间断式沟道202的第二部分2022相互对应，间断式沟道201的第一部分2011长度大于间断式沟道202的第一部分2021的长度。
本发明通过在所述显示区110与所述通孔120之间设置一阻挡区130，所述阻挡区130具有多条沟道，并在相邻沟道之间设置阻挡块1021形成阻挡结构，这可以有效的阻隔水氧入侵所述显示面板100的显示区110。并且所述沟道交错分布于所述阻挡区130，这更进一步的隔绝水氧，进而保护所述显示区110，最终提高所述显示面板100的稳定性。
如图6所示，在所述显示区110，所述显示面板100还包括第一电极104。
所述薄膜晶体管层103设于所述无机绝缘层102远离所述基板101的一侧。
所述薄膜晶体管层103包括：半导体层1031、第一栅极绝缘层1032、第一栅极1033、第二栅极绝缘层1034、第二栅极1035、层间绝缘层1036、第三金属层1037以及平坦化层1038。
所述半导体层1031设于所述无机绝缘层102远离所述基板101的一侧；所述半导体层1031的材料为多晶硅或单晶硅。
所述第一栅极绝缘层1032设于所述无机绝缘层102以及所述半导体层1031上；所述第一栅极绝缘层1032主要起到将相邻的金属层之间绝缘，防止影响工作。
所述第一栅极1033设于所述第一栅极绝缘层1032远离所述无机绝缘层102的一侧；所述第二栅极绝缘层1034设于所述第一栅极1033以及所述第一栅极绝缘层1032上；所述第二栅极1035设于所述第二栅极绝缘层1034远离所述第一栅极绝缘层1032的一侧。
所述层间绝缘层1036设于所述第二栅极绝缘层1034以及第二栅极1035上；所述第三金属层1037设于所述层间绝缘层1036远离所述第二栅极绝缘层1034的一侧。
所述平坦化层1038设于所述第三金属层1037以及所述层间绝缘层1036上。
所述第一电极104设于所述薄膜晶体管层103远离所述无机绝缘层102的一侧且连接所述薄膜晶体管层103。
所述像素限定层105，设于所述第一电极104以及所述薄膜晶体管层103上，其中，所述像素限定层105具有一开口106，第一电极104部分暴露于所述开槽106中。所述有机发光层107设于所述第一电极104上。
本发明还提供一种显示装置，包括所述显示面板100以及摄像模块，所述摄像模块设于所述显示面板100下且对应所述通孔120。
所述显示装置通过在所述显示区110与所述通孔120之间设置一阻挡区130，所述阻挡区具有多条沟道，并在相邻沟道之间设置阻挡块1021形成阻挡结构，这可以有效的阻隔水氧通过阻挡区130的有机发光层107入侵所述显示面板100的显示区110的有机发光层107。并且所述沟道可以设置成波形，可以增加沟道的面积，这更进一步增加了封装层108,在所述阻挡区130的面积，可以有效的隔绝水氧入侵，进而保护所述显示区110，最终提高所述显示装置的稳定性。
本发明的技术范围不仅仅局限于所述说明中的内容，本领域技术人员可以在不脱离本发明技术思想的前提下，对所述实施例进行多种变形和修改，而这些变形和修改均应当属于本发明的范围内。
