 本发明的实施方式
以下各实施例的说明是参考附加的图示，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如[上]、[下]、[前]、[后]、[左]、[右]、[内]、[外]、[侧面]等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。在图中，结构相似的单元是用以相同标号表示。
本发明针对现有的显示面板中，BM下方未设置金属的区域，如显示面板的边缘区域，光线强度较大时，光线会穿透BM，从而产生边缘漏光现象，影响显示品质的技术问题。
一种显示面板，如图1所示，所述显示面板10具有显示区11和位于所述显示区11的侧部的边缘区12；所述显示面板10包括第一基板13、第二基板14以及背光模组15，所述第一基板13与所述第二基板14相对设置，所述第一基板13可以为阵列基板，所述第二基板14可以为彩膜基板。
具体的，所述第一基板13包括第一衬底基板131、设置于所述第一衬底基板131靠近所述第二基板14的一侧的第一配向膜层133，以及，设置于所述第一衬底基板131远离所述第二基板14的一侧的第一偏光片134。
具体的，所述第二基板14包括第二衬底基板141、设置于第二衬底基板141靠近所述第一基板13的一侧上的第二配向膜层142，以及，设置于第二衬底基板141远离第二基板14的一侧的第二偏光片143。
具体的，所述背光模组15包括背框151以及设置于所述第一基板13远离所述第二基板14的一侧的背光源152，背框151通过一胶层161粘结于所述第一基板13远离所述第二基板14的一侧上。
具体的，所述第一基板13或/和所述第二基板14上设置有位于所述边缘区12的遮光层162。
具体的，所述第一基板13或/和所述第二基板14上设置有位于所述显示区11和所述边缘区12的黑色矩阵163，所述黑色矩阵163与遮光层162位于不同膜层。
需要说明的是，通过在边缘区12处设置遮光层162，通过遮光层162与黑色矩阵163结合，对于未设置金属的边缘区12，强度较大的光线即使穿透遮光层162和黑色矩阵163中的一者后，光线也会被遮光层162和黑色矩阵163中的另一者遮挡，从而避免产生边缘漏光影响显示品质。
需要说明的是，图1中仅示意了遮光层162设置于所述第一衬底基板131与所述第一配向膜层133之间的情况，实际实施中，遮光层162还可以设置于第一基板13的其他膜层上，遮光层162也可以设置于第二基板14上。
具体的，所述黑色矩阵163在所述第一基板13上的正投影覆盖所述遮光层162在所述第一基板13上的正投影，以提升遮光效果。
在一实施方式中，所述黑色矩阵163设置于所述第二衬底基板141与所述第二配向膜层142之间。
具体的，所述显示面板10还包括设置于所述第一基板13和所述第二基板14之间的框胶164，所述框胶164与所述第一基板13和所述第二基板14之间形成一容纳腔，所述容纳腔中设置有液晶层165，所述遮光层162位于所述框胶164的内侧，以减小显示面板10的边框宽度。
具体的，所述第一基板13和所述第二基板14的侧部设置有挡光层166，挡光层166覆盖第一基板13与第二基板14之间的间隙，以避免光线穿透框胶164后射出导致边缘漏光，同时可以防止水汽通过间隙进入到显示面板10内。
在一实施方式中，所述第一基板13还包括设置于所述第一衬底基板131靠近所述第二基板14的一侧的色阻层132，所述遮光层162与所述色阻层132同层设置，以减小显示面板10的整体厚度。
其中，所述色阻层132包括多个间隔设置的色阻块，色阻块可以为红色色阻块、蓝色色阻块和绿色色阻块中的一种或多种，所述黑色矩阵163与相邻两所述色阻块之间的间隔区对应设置。
需要说明的是，所述色阻层132可以设置于所述第一衬底基板131与所述第一配向膜层133之间，色阻层132还可以设置于所述第二衬底基板141与所述第二配向膜层142之间。
具体的，所述遮光层162的制备材料与所述色阻层132的制备材料相同，所述遮光层162可以与所述色阻层132通过同一道工序形成，如在第一衬底基板131上使用色阻材料形成一色阻膜层后，对色阻膜层进行图案化，以形成所述色阻层132和所述遮光层162，减少显示面板10的制备工序，降低生产成本。
具体的，所述遮光层162的制备材料包括蓝色色阻。
需要说明的是，不同颜色的光在黑色矩阵163上的穿透率不同，一般长波段的光（如红光）在黑色矩阵163上的穿透率高，因此红光容易穿透黑色矩阵163。
参见图2，图2为不同波长的光线在不同颜色的光阻上的穿透率的示意图，图2中纵坐标为穿透率，横坐标为光线的波长，点画线为蓝色色阻的穿透率曲线，粗实线为绿色色阻的穿透率曲线，细实线为红色色阻的穿透率曲线。由图2可知，长波段的光在蓝色色阻上的穿透率较低，利用蓝色色阻可以对长波段的光起到良好的遮挡作用，从而进一步提升遮光效果，避免产生边缘漏光影响显示品质。
需要说明的是，挡光层166的制备材料与遮光层162的制备材料可以相同，以起到更强的遮光作用。挡光层166的制备材料与遮光层162的制备材料也可以不相同，如挡光层166的制备材料为绿色色阻或红色色阻，短波段的光在绿色色阻和红色色阻上的穿透率低，挡光层166和遮光层162可以起到互补作用。
具体的，如图3和图4所示，所述边缘区12包括第一边缘区121和第二边缘区122，所述显示面板10还包括位于所述第二边缘区122处的信号输入端子167，所述遮光层162位于所述第一边缘区121。
需要说明的是，信号输入端子167由金属材料形成，信号输入端子167可以与显示面板10外部的驱动模块20连接，以接入驱动模块20提供的输入信号，而信号输入端子167为金属块，背光源152发出的光线会在信号输入端子167上发生反射，避免强度较大的光线直射至黑色矩阵163上导致边缘漏光，因此可以仅在第一边缘区121设置遮光层162，无需在设置有信号输入端子167的第二边缘区122处设置遮光层162，降低生产成本，同时防止遮光层162对信号输入端子167与驱动模块20的连接造成阻碍。
具体的，所述第一边缘区121和所述第二边缘区122分别位于所述显示区11的不同侧部。
具体的，所述遮光层162在所述第一基板13上的正投影覆盖所述第一边缘区121在所述第一基板13上的正投影，以起到更好的遮光作用。
在一实施方式中，所述第一基板13上设置有位于所述第一边缘区121远离所述显示区11的一侧的GOA驱动单元168，所述GOA驱动单元168设置有多个且沿纵向间隔排布，GOA驱动单元168为所述显示面板10提供驱动信号。
需要说明的是，可以仅在所述第一基板13的一侧上设置所述GOA驱动单元168，也可以在所述第一基板13的多侧上均设置所述GOA驱动单元168。
需要说明的是，所述遮光层162可以覆盖所述GOA驱动单元168或不覆盖所述GOA驱动单元168。
如图5所示，所述第一基板13还包括设置于所述第一衬底基板131上的有源层135a、覆盖所述有源层135a的栅极绝缘层135b、设置于所述栅极绝缘层135b上的栅极135c、覆盖所述栅极135c的层间介质层135d、设置于所述层间介质层135d上且与所述有源层135a电连接的源漏极135e以及覆盖所述源漏极135e的钝化层135f。
其中，所述色阻层132和所述遮光层162设置于所述钝化层135f上，所述色阻层132上还设置有与所述源漏极135e电连接的像素电极136，所述第一配向膜层133覆盖所述像素电极136。
基于上述显示面板10，本申请还提供一种显示装置，如图6所示，所述显示装置包括驱动模块20以及如上述任一实施方式中所述的显示面板10，所述驱动模块20与所述显示面板10的信号输入端子167电连接，以用于驱动所述显示面板10正常工作。
需要说明的是，所述驱动模块20可以为覆晶薄膜板或其他印刷电路板。
本发明的有益效果为：通过在边缘区12处设置遮光层162，通过遮光层162与黑色矩阵163结合，对于未设置大量金属的边缘区12，强度较大的光线即使穿透遮光层162和黑色矩阵163中的一者后，光线也会被遮光层162和黑色矩阵163中的另一者遮挡，从而避免产生边缘漏光影响显示品质，同时遮光层162与色阻层132可以采用同样的材料并通过同一道工序形成，不会增加生产成本和显示面板10的整体厚度。
在上述实施例中，对各个实施例的描述都各有侧重，某个实施例中没有详述的部分，可以参见其他实施例的相关描述。
本文中应用了具体个例对本申请的原理及实施方式进行了阐述，以上实施例的说明只是用于帮助理解本申请的技术方案及其核心思想；本领域的普通技术人员应当理解：其依然可以对前述各实施例所记载的技术方案进行修改，或者对其中部分技术特征进行等同替换；而这些修改或者替换，并不使相应技术方案的本质脱离本申请各实施例的技术方案的范围。
