OLED显示装置也存在类似的问题。OLED显示装置通常包括相对设置OLED基板和玻璃基板，在玻璃基板上贴合有防眩光的圆偏光片、在玻璃基板的出光面侧贴合有硬度更高的保护玻璃以对OLED显示装置的玻璃基板进行保护。

附图说明
图1为本公开的实施例的显示装置的示意图。
具体实施方式
为使本领域技术人员更好地理解本公开的技术方案，下面结合附图和具体实施方式对本公开作进一步详细描述。
如图1所示，本实施例提供一种显示装置，包括相对设置的第一基板和第二基板。其中，第一基板包括第一基底1，第二基板包括第二基底2，并且第二基底2的厚度不小于第一基底1的厚度的1.5倍。此外，在第二基底2中包括防眩光膜层(未示出)。
在现有技术中，第一基板的第一基底1和第二基板的第二基底2的材质和厚度通常是一样，而在本实施例中第二基底2的厚度是不小于第一基底1的厚度的1.5倍的，也即选取较厚的第二基底2，此时第二基底2同时可以作为现有显示装置中的保护玻璃，从而可以省略在制造显示模组时贴合保护玻璃的步骤。在一些实施例中，第一基底1的厚度可小于0.7mm，第二基底2的厚度可大于1.1mm。此外，在本实施例中，采用在第二基底2中进行防眩光膜层处理替代在第二基底2上贴合圆偏光片，从而可以省略贴合圆偏光片的步骤。因此，通过使第二基底2的厚度不小于第一基底1的厚度的1.5倍、并且在第二基底2中进行防眩光膜层处理，可以提高显示装置的生产效率和成品率，当然省略了贴合步骤也就少了在第二基板上涂覆光学胶水的步骤，从而还可以提高显示装置的显示亮度。
如图1所示，第一基板还包括绑定区11，在所述绑定区11中的绑定线路的背离所述第一基底的一侧覆盖有保护结构3，其中，保护结构3与绑定区11接触的面与第二基底2正对第一基底1的面齐平，以防止由于第二基底2与绑定线路之间的段差过大，导致后续整机组装后，显示装置在该位置出现破碎的问题。此外，保护结构3可以至少覆盖绑定区11中的绑定线路的背离所述第一基底1的一侧。图1示出了保护结构3覆盖绑定区11中的绑定线路的背离第一基底1的一侧的情况，但是本公开不限于此。例如，保护结构3还可以覆盖绑定区11的背离第二基底2的侧表面。在此需要说明的是，绑定线路是指向第一基板中的像素电路提供信 号的线路，像素电路的信号线位于绑定线路的靠近第一基底1的一侧，在绑定线路的背离第一基底1的一侧具有绑定端子4，以用于在后续绑定工艺中与绑定线路进行绑定。
在一些实施例中，绑定线路上的保护结构3采用紫外光固化胶，由于紫外光固化胶通常用于对第一基板和第二基板进行封装，因此可以在进行封装的同时形成保护结构3，从而并不会增加工艺步骤，也不会造成成本的增加。
此外，如图1所示，第二基底2背离保护结构3的面突出于第一基底1背离保护结构3的侧表面。此时，可以通过第二基底2保护第一基板，而且第二基底2的突出于第一基板的第一基底1的区域是非显示区，因此可以在这部分域内丝印图标，例如显示装置的品牌logo等。当然，在第二基底2背离所述第一基底1的面的周边区域上均可以设置图标。
此外，如图1所示，本实施例中的显示装置还包括壳体5，壳体5将除了第二基底2背离第一基底1的面以及第二基底2背离保护结构3的面之外的所述显示装置的表面覆盖，用于保护显示装置的内部结构。壳体5的材料可以是金属也可以是树脂等其它材质。
其中，本实施例中的第二基板和第一基板可以分别是TFT-LCD显示装置的彩膜基板和阵列基板(即，所述显示装置为TFT-LCD显示装置)，也可以是OLED显示装置的玻璃基板和OLED基板(即，所述显示装置为OLED显示装置)。
其中，第一基板和第二基板之间可以通过密封胶6密封，该密封胶6可以为紫外光固化胶。
此外，本实施例中的显示装置可以用于电子纸、手机、液晶面板、平板电脑、电视机、显示器、笔记本电脑、数码相框、导航仪等任何具有显示功能的产品或部件。
可以理解的是，以上实施方式仅仅是为了说明本公开的原理而采用的示例性实施方式，然而本公开并不局限于此。对于本领 域内的普通技术人员而言，在不脱离本公开的精神和实质的情况下，可以做出各种变型和改进，这些变型和改进也视为本公开的保护范围。
