所述第一透光层113为绝缘基板，例如玻璃基板、石英基板等。
所述第一偏光片111设于所述第一透光层113的一表面上。所述遮光层112与所述第一偏光片111同层设置，并且所述遮光层112包围所述第一偏光片111。其中，所述第一偏光片111对应于所述显示面板100的透光区101，所述遮光层112对应于所述显示面板100的遮光区102。所述第一偏光片111用于解析显示面板100中经过液晶电调制后的偏振光，产生明暗对比，从而产生显示画面。所述遮光层112用于为所述显示面板100的边缘遮光，防止光线漏出，影响显示效果。
所述黑色矩阵114设于所述第一透光层113远离所述第一偏光片111的一表面上，并从所述显示面板100的透光区101延伸至所述遮光区102的边缘。所述黑色矩阵114用于分割彩色滤光片中的相邻色阻，遮挡色彩的空隙，防止漏光或者混色，保证三色彩色滤光片的遮光效果。
在本发明的其他实施例中，所述黑色矩阵114还可以如图3所示对应于所述透光区101，其层状结构与本实施例中所提供的显示面板100相似，因此不在此做过多赘述。基于本申请中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所获得的所有其它实施例，都属于本申请保护的范围。
所述导电层115覆于所述黑色矩阵114和所述第一透明层上，所述导电层115为氧化铟锡透明导电膜层。所述导电层115用于在通电后产生电场，通过电场控制改变显示面板100中液晶分子的偏转角度，从而改变光线的透过率。
所述第一配向膜116覆于所述导电层115远离所述黑色矩阵114的一表面上，所述第一配向膜116的材料中包括聚贤亚胺。
所述第二基板层120中包括一第二透光层122、一第二偏光片121以及一第二配向膜123。
所述第二透光层122为绝缘基板，例如玻璃基板、石英基板等。
所述第二偏光片121设于所述第二透光层122的一表面上。所述第二偏光片121用于将显示装置中背光源产生的光束转换为偏振光。
所述第二配向膜123覆于所述第二透光层122远离所述第二偏光片121的一表面上，所述第二配向膜123的材料中包括聚贤亚胺。所述第二配向膜123与第一基板层110中的第一配向膜116均用于在电场关闭后使液晶分子恢复原有的排列角度。
所述密封层130设于所述第一基板层110与第二基板层120之间，并且所述密封层130上具有一凹槽131，所述黑色矩阵114的边缘预计覆于所述黑色矩阵114上的部分导电层115和第一配向膜116也均设于所述凹槽131中。其中，所述凹槽131的深度小于等于所述黑色矩阵114的厚度、所述导电层115的厚度以及所述第一配向膜116的厚度之和。所述密封层130用于贴合第一基板层110和第二基板层120，同时将所述黑色矩阵114的边缘也包裹在密封层130中，防止水汽侵入而导致的黑色矩阵114剥落。
本发明实施例中所述提供的显示面板100及显示装置，通过将黑色矩阵114的边缘内嵌至所述密封层130中，通过所述密封层130保护所述黑色矩阵114，防止其被水汽侵蚀，从而提高显示面案的信赖性以及稳定性。并且，通过在第一偏光片111的边缘设置遮光层112，在不增加显示面板100厚度的同时保证了显示面板100遮光区102的遮光效果。
虽然在本文中参照了特定的实施方式来描述本发明，但是应该理解的是，这些实施例仅仅是本发明的原理和应用的示例。因此应该理解的是，可以对示例性的实施例进行许多修改，并且可以设计出其他的布置，只要不偏离所附权利要求所限定的本发明的精神和范围。应该理解的是，可以通过不同于原始权利要求所描述的方式来结合不同的从属权利要求和本文中所述的特征。还可以理解的是，结合单独实施例所描述的特征可以使用在其他所述实施例中。
