具体实施方式
需要理解的是，这里所使用的术语、公开的具体结构和功能细节，仅仅是为了描述具体实施例，是代表性的，但是本申请可以通过许多替换形式来具体实现，不应被解释成仅受限于这里所阐述的实施例。
在本申请的描述中，术语“第一”、“第二”仅用于描述目的，而不能理解为指示相对重要性，或者隐含指明所指示的技术特征的数量。由此，除非另有说明，限定有“第一”、“第二”的特征可以明示或者隐含地包括一个或者更多个该特征；“多个”的含义是两个或两个以上。术语“包括”及其任何变形，意为不排他的包含，可能存在或添加一个或更多其他特征、整数、步骤、操作、单元、组件和/或其组合。
另外，“中心”、“横向”、“上”、“下”、“左”、“右”、“竖直”、“水平”、“顶”、“底”、“内”、“外”等指示的方位或位置关系的术语，是基于附图所示的方位或相对位置关系描述的，仅是为了便于描述本申请的简化描述，而不是指示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作，因此不能理解为对本申请的限制。
此外，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，或是两个元件内部的连通。对于本领域的普通技术人员而言，可以根据具体情况理解上述术语在本申请中的具体含义。
如图1和图2所示，在液晶面板用了五年或者更久后，辅助密封层(Tuffy胶)遇到温度或者外力后会收缩。收缩后第一基板(如彩膜基板，Color Filter，CF基板)就会裸露出来，由于CF基板侧覆盖一整面导电层(Indium Thin Oxides，ITO，透明导电薄膜)，在框胶外侧的ITO暴漏在空气中。在日常使用中接触到水汽或者清洗剂接触，这些具有腐蚀性的物质接触到CF基板的ITO后，慢慢就会腐蚀ITO。严重情况下，CF基板的ITO会由显示区外围腐蚀进显示区内，造成面板显示缺陷，例如腐蚀区域黑团缺陷。
下面参考附图和可选的实施例对本申请作进一步说明。
如图3和图6所示，本申请实施例公布了一种显示面板100，所述显示面板100包括：第一基板110；与所述第一基板110对置设置的第二基板120；设置在所述第一基板110上的导电层130；夹设于所述第一基板110和第二基板120之间的框胶140，且位于所述第一基板110和第二基板120的边缘位置；设置在所述第一基板110边缘的防护层150，所述框胶140的外侧，覆盖在所述导电层130对应所述框胶140外侧的部分；设置在所述框胶140的外侧、与所述框胶140紧密贴合的辅助密封层160，并覆盖所述防护层150。本实施例中，胶框的外侧为：胶框远离显示面板100显示区210一侧，在辅助密封层160一侧。
显示面板100在框胶140的外侧设置有辅助密封层160，该辅助密封层160可以对框胶140起到辅助密封和支撑的作用，同时对导电层130起到防护作用，避免腐蚀等情况，但是在使用时间较长时，在显示面板100边缘的辅助密封层160遇到温度或外力后会收缩，与第一基板110之间会产生缝隙甚至脱离，第一基板110裸露出来，失去辅助密封层160的防护，该第一基板110上的导电层130会暴露在空气中，被水汽或其他腐蚀性物质腐蚀，甚至从显示面板100的显示区210域外围向显示区210域进行腐蚀，使显示面板100的显示区210域边缘出现显示缺陷，形成腐蚀区或黑团缺陷。本申请在显示面板100边缘，第一基板110上设置一防护层150，防护层150设置在框胶140外侧，防护层150在第一基板110上的导电层130上，再在防护层150外侧设置一辅助密封层160，如此，对于该导电层130来说，该防护层150和辅助密封层160都能对它给予蚀刻防护等，而即便是辅助密封层160收缩时，该防护层150依然可以防止导电层130与空气的接触，有效的减少显示面板100的显示区210域边缘的腐蚀区或黑团缺陷。
在一实施例中，所述显示面板100包括显示区210和非显示区220，所述第一基板110对应显示区210设置有色阻层240；所述防护层150与所述色阻层240同层形成。本方案中，非显示区220域的防护层150与显示区210域的色阻层240为同层形成的，在显示面板100的显示区210域形成色阻层240的同时，就可以在显示面板100边缘同时形成防护层150，可以节省额外新增一个单独的防护层150带来新的制程，不增加光罩数，不用其他更多步骤来形成防护层150，免除多余制程带来的时间，并有利于降低生产成本。
在一实施例中，所述色阻层240包括第一色阻层241、第二色阻层242和第三色阻层243；所述防护层150与所述第一色阻层241、第二色阻层242和第三色阻层243中的一种同层形成。本方案中的防护层150与色阻层240中的第一色阻层241、第二色阻层242和第三色阻层243中的一种同层形成，与三个色阻层240中的一种同层形成，可以防止增加新的制程，不增加光罩数，不用其他更多步骤来形成防护层150，免除多余的制程带来的时间。
在一实施例中，如图5和图6所示，所述色阻层240包括第一色阻层241、第二色阻层242和第三色阻层243；所述防护层150包括与第一色阻层241同层形成的第一防护层151、与第二色阻层242同层形成的第二防护层152、与第三色阻层243同层形成的第三防护层153中的至少两种。本方案中的防护层150与色阻层240中的第一色阻层241、第二色阻层242和第三色阻层243中的至少两种同层形成，可以防止增加新的制程，不增加光罩数，不用其他更多步骤来形成防护层150，免除多余的制程带来的时间；同时，多层的防护层150可以进一步保护导电层130，避免一层防护层150容易被破坏，本申请不限制防护层150的层数，只要能保护到导电层130，并且不影响显示面板100的显示和导电层130导电即可。
在一实施例中，所述第二基板120对应非显示区220设置有第一金属层200，所述框胶 140设置在第一金属层200和导电层130之间；所述框胶140内部设置有导电介质190，所述导电介质190导通所述导电层130和第一金属层200。本方案中，在第二基板120上设置有第一金属层200，第一基板110与第二基板120夹设的框胶140内部设置导电介质190(实际上为金球)，导电介质190导通第一金属层200与导电层130之间的信号传输(主要是第一基板110和第二基板120的公共电极连通)，促进两个基板之间的信号传输，在第一基板上导电层与基板之间还设置有遮光层250，遮光层250为显示区域的遮光作用，在非显示区域也有设置。
在一实施例中，所述第一基板110对应所述框胶140的内侧设置有配向层170；所述配向层170和所述框胶140之间设置有间隙180。在框胶140与配向层170之间设置有间隙180，防止该框胶140有可能出现的向显示区210域内配向层170渗透的情况，避免框胶140对配向层170的性能的影响的可能性，保证显示区210域边缘的显示效果。
在一实施例中，所述间隙180的宽度为500-1000微米。本方案中，在框胶140与配向层170之间设置有间隙180，间隙180的宽度设置在500至1000微米，设置间隙180大于等于500微米，可以有效的防止该框胶140有可能出现的向显示区210域内配向层170渗透的情况，避免框胶140对配向层170的性能的影响的可能性，保证显示区210域边缘的显示效果；同时，设置间隙180小于等于1000微米，避免间隙180太宽，影响显示区210边缘的显示效果或者带来宽边框，当然间隙180的设置也可以更小，只要不影响配向层170的性能即可，如10微米至1000微米也是可以的。
在一实施例中，如图4所示，所述第一基板110和第二基板120之间、所述框胶140内设置有液晶层230；所述防护层150还覆盖所述导电层130远离所述液晶层230的端部。本方案中，在第一基板110与第二基板120之间还设置有液晶层230，并且液晶层230设置在胶框的内侧，在远离液晶层230的一侧；该防护层150不仅设置在导电层130靠近第二基板120的侧面，而且导电层130端部也设置有防护层150，防护层150在侧边阻挡水汽等腐蚀性物质，防止导电层130从端部被腐蚀，慢慢的腐蚀到显示区210域的情况发生，更好的避免影响显示面板100的显示效果。
在一实施例中，所述第一基板110对应所述框胶140的内侧设置有配向层170，所述防护配向层260与所述配向层170同层形成。本方案中，防护配向层260与配向层170同层形成，在显示面板100的显示区210域涂布配向层170的同时，就可以在显示面板100边缘同时进行涂布设置防护配向层260(或者保留该防护配向层260不对其进行蚀刻)，可以节省额外新增一个单独的防护配向层260带来新的制程，免除多余制程带来的时间，并有利于降低生产成本。
在一实施例中，所述显示面板100包括显示区210和非显示区220，所述第一基板110 对应所述非显示区220处设置有遮光层250、所述导电层130和所述配向层170依次设置在所述遮光层250靠近第二基板120的一侧；所述配向层170和防护配向层260对应所述框胶140的位置镂空，所述框胶140设置在所述导电层130和第二基板120之间。本方案中，配向层170和防护配向层260的镂空位置设置框胶140，且框胶140还设置在导电层130和第二基板120之间，配向层170位于显示区210域，防护配向层260位于非显示区220域，且框胶140在非显示区220域，直接与所述导电层130接触，可以避免配向液的浪费。
在一实施例中，如图4和图6所示，所述显示面板100包括显示区210和非显示区220，所述第一基板110对应所述非显示区220处设置有遮光层250、所述导电层130和所述配向层170依次设置在所述遮光层250靠近第二基板120的一侧；所述配向层170和防护配向层260一体成型，所述框胶140设置在所述配向层170和第二基板120之间，即框胶140设置在配向层170与防护配向层260的接触部和第二基板120之间；本实施例还可以将第二基板120上的配向层170延长至胶框外侧，与第一基板110的配向层170的长度位置相同，可以保护第二基板120上的第一金属层200。
本方案中，在非显示区220域设置有遮光层250、导电层130和配向层170(或者说显示区210配向层170的延伸部)，第一基板110一侧，在涂布配向层170时，直接涂布到第一基板110的边缘位置，将显示区210域上的导电层130全部覆盖，方便配向液的涂布和控制，减少形成配向层170和防护配向层260的难度，同时，增高该第一基板110，使得第一基板110和第二基板120之间的距离变小，使得该框胶140的厚度变薄，减少框胶140的材料使用。
在一实施例中，所述第二基板120对应非显示区220设置有第一金属层200，所述框胶140设置在第一金属层200和配向层170之间；所述框胶140内部设置有导电介质190，所述导电介质190透过所述配向层170，导通所述导电层130和第一金属层200。本方案中，在配向层170与防护配向层260完全覆盖导电层130时，由于配向层170为绝缘材料，框胶140内的导电介质190(实际上为金球)无法将第一基板110与第二基板120(主要是第一基板110和第二基板120的公共电极连通)的信号进行传输，因此，框胶140中的导电介质190将配向层170刺穿或者通过过孔等方式，连通于该导电层130，实现两个基板之间的信号传输。
在一实施例中，如图5所示，所述第一基板110和第二基板120之间、所述框胶140内设置有液晶层230；所述防护配向层260还覆盖所述导电层130远离所述液晶层230的端部。本方案中，在第一基板110与第二基板120之间还设置有液晶层230，并且液晶层230设置在胶框的内侧，在远离液晶层230的一侧；该防护配向层260不仅设置在导电层130靠近第二基板120的侧面，而且导电层130端部也设置有防护配向层260，防护配向层260在侧边 阻挡水汽等腐蚀性物质，防止导电层130从端部被腐蚀，慢慢的腐蚀到显示区210域的情况发生，更好的避免影响显示面板100的显示效果。
本实施例还可以将第一基板与第二基板设置为相同的长度；这样设计可以延长配向层从侧面腐蚀进显示面板区域的时长，进一步延长显示面板的寿命。
如图3所示，作为本申请的另一实施例，公开了一种显示面板100，所述显示面板100包括：第一基板110；与所述第一基板110对置设置的第二基板120；设置在所述第一基板110上的导电层130；夹设于所述第一基板110和第二基板120之间的框胶140，且位于所述第一基板110和第二基板120的边缘位置；设置在所述第一基板110边缘，所述框胶140的外侧的防护层150，覆盖在所述导电层130对应所述框胶140外侧的部分；设置在所述框胶140的外侧、与所述框胶140紧密贴合的辅助密封层160，并覆盖所述防护层150；显示区210和非显示区220，所述第一基板110对应显示区210设置有色阻层240；所述防护层150与所述色阻层240同层形成；所述第一基板110对应所述框胶140的内侧设置有配向层170；所述配向层170和所述框胶140之间设置有间隙180；所述间隙180的宽度为500-1000微米。
在显示面板100边缘，第一基板110上设置一防护层150，防护层150设置在框胶140外侧，防护层150在第一基板110上的导电层130上，再在防护层150外侧设置一辅助密封层160，防护层150与所述配向层170同层形成，可以节省额外新增一个单独的防护层150带来新的制程，免除多余制程带来的时间，并有利于降低生产成本；在框胶140与配向层170之间设置有间隙180，间隙180的宽度设置在500至1000微米，设置间隙180大于等于500微米，可以有效的防止该框胶140有可能出现的向显示区210域内配向层170渗透的情况，避免框胶140对配向层170的性能的影响的可能性，保证显示区210域边缘的显示效果；同时，设置间隙180小于等于1000微米，避免间隙180太宽，影响显示区210边缘的显示效果或者带来宽边框；对于该导电层130来说，该防护层150和辅助密封层160都能对它给予蚀刻防护等，而即便是辅助密封层160收缩时，该防护层150依然可以防止导电层130与空气的接触，有效的减少显示面板100的显示区210域边缘的腐蚀区或黑团缺陷。
如图3和图7所示，作为本申请的另一实施例，公开了一种显示装置300，包括上述的显示面板100。
本实施例的显示装置与以上所述的显示面板具有相同的作用，上述显示面板的作用，本显示装置也是可以使用的。
本申请的技术方案可以广泛用于各种显示面板，如TN型显示面板(全称为Twisted Nematic，即扭曲向列型面板)、IPS型显示面板(In-Plane Switching，平面转换)、VA型显示面板(Vertical Alignment，垂直配向技术)、MVA型显示面板(Multi-domain Vertical Alignment，多象限垂直配向技术)，当然，也可以是其他类型的显示面板，如有机发光显示 面板(organic light-emitting diode，简称OLED显示面板)，均可适用上述方案。
以上内容是结合具体的可选实施方式对本申请所作的进一步详细说明，不能认定本申请的具体实施只局限于这些说明。对于本申请所属技术领域的普通技术人员来说，在不脱离本申请构思的前提下，还可以做出若干简单推演或替换，都应当视为属于本申请的保护范围。
