附图说明
[0020] 图1为本发明实施例提供的一种显示面板的结构示意图;
[0021] 图2为本发明实施例提供的一种显示装置的结构示意图;
[0022] 图3为本发明实施例提供的另一种显示装置的结构示意图;
[0023] 图4为本发明实施例提供的另一种显示装置的结构示意图。
具体实施方式
[0024] 下面将结合本发明实施例中的附图,对本发明实施例中的技术方案进行清楚、完 整地描述,显然,所描述的实施例仅仅是本发明一部分实施例,而不是全部的实施例。基于 本发明中的实施例,本领域普通技术人员在没有做出创造性劳动前提下所获得的所有其他 实施例,都属于本发明保护的范围。
[0025] 请参考图1、图2、图3和图4,图1为本发明实施例提供的一种显示面板的结构示意 图;图2为本发明实施例提供的一种显示装置的结构示意图;图3为本发明实施例提供的另 一种显示装置的结构示意图;图4为本发明实施例提供的另一种显示装置的结构示意图。
[0026] 如图1所示,本发明提供的显示面板,包括上基板1、下基板2、位于上基板1和下基 板2之间的液晶层5和位于液晶层5—侧的公共电极3,公共电极3具有线栅偏振结构以形成 检偏偏光结构或者起偏偏光结构。
[0027] 上述显示面板中,公共电极3具有线栅偏振结构以形成检偏偏光结构或者起偏偏 光结构,从而该公共电极3可以用于光的起偏或者检偏;当公共电极3用于光的起偏时,该显 示面板中可以省去起偏偏光结构,当公共电极3用于光的检偏时,该显示面板中可以省去检 偏偏光结构。综上所述,上述显示面板中可以省略检偏偏光片或者起偏偏光片,从而可以减 少显示面板的结构层数,进而可以减小显示装置的厚度。
[0028] 如图1所示,一种具体的实施例中,显示面板中,公共电极3位于液晶层5朝向上基 板1 一侧以形成检偏偏光结构,且液晶层5朝向下基板2—侧设有起偏偏光片7。
[0029] 上述显示面板中,公共电极3位于上基板1与液晶层5之间,可以用于光的检偏,因 此,该显示面板中可以省略检偏偏光片,从而使显示面板厚度较小。
[0030] 如图1所示,在上述实施例的基础上,一种优选的实施例中,起偏偏光片7可以为线 栅偏光膜。
[0031] 如图1所示,在上述实施例的基础上,一种具体的实施例中,上述显示面板还包括 彩膜层4和阵列层6;彩膜层4可以位于公共电极3与液晶层5之间,阵列层6可以位于起偏偏 光片7与液晶层5之间。
[0032] 如图2、图3和图4所示,一种具体的实施例中,显示面板中,公共电极3位于液晶层5 朝向下基板2—侧以形成起偏偏光结构。
[0033] 如图2、图3和图4所示,显示面板中,公共电极3位于下基板2与液晶层5之间,可以 用于光的起偏,因此,该显示面板中可以省去起偏偏光片,从而使显示面板厚度较小。另外, 公共电极3位于下基板2与液晶层5之间还可以避免公共电极3中的线栅偏振结构对光的反 射影响到显示区。
[0034]如图2所示,在上述实施例的基础上,一种优选的实施例中,显示面板还可以包括 位于上基板1背离下基板2—侧的防静电层8。防静电层8可以屏蔽静电,以防止静电对液晶 盒内的液晶产生干扰。
[0035]优选地,防静电层8可以具有线栅偏振结构以形成检偏偏光结构。防静电层8的线 栅偏振结构可以用于光的检偏,因此,在可以有效防止静电干扰的同时,上述显示面板还可 以省略检偏偏光片,从而使显示面板的厚度更小、更加薄型化。
[0036]当公共电极形成起偏偏光结构时,一种具体的实施例中,显示面板中还包括阵列 层6和彩膜层4,其中,阵列层6和彩膜层4的位置关系可以为以下情况:
[0037]方式一,如图3所示,彩膜层4位于公共电极3和液晶层5之间,阵列层6位于上基板1 和液晶层5之间。
[0038]方式二,如图2所示,彩膜层4位于液晶层5与上基板1之间,阵列层6位于公共电极3 与液晶层5之间。
[0039] 方式三,如图4所示,彩膜层4位于液晶层5与上基板1之间,阵列层6位于彩膜层4与 液晶层5之间。
[0040]当公共电极位于液晶层5与下基板2之间时,一种具体的实施例中,上述显示面板 还包括位于液晶层5与下基板2之间的多条交叉设置的栅线和数据线以形成多个阵列分布 的像素单元,公共电极3形成与像素单元一一对应的公共电极单元。
[0041] 更具体地,显示面板为ADS模式的显示面板,每一个公共电极单元与栅线同层设 置,且公共电极3朝向液晶层5的一侧设有具有条形结构的像素电极。
[0042] 当然,上述显示装置还可以为IPS模式的显示装置。
[0043] 如图2、图3和图4所示,本发明实施例还提供一种显示装置,该显示装置可以包括 上述任意一种实施例中提供的显示面板。
[0044] 如图2、图3和图4所示,在上述实施例的基础上,一种具体的实施例中,显示面板的 下基板2可以为导光板,此时,下基板2背离上基板1的一侧设有反射板9,下基板2的至少一 个侧面设有灯条10。下基板2直接作为导光板可以减少显示装置的结构层数,使得显示装置 更加薄型化。
[0045] 显然,本领域的技术人员可以对本发明实施例进行各种改动和变型而不脱离本发 明的精神和范围。这样,倘若本发明的这些修改和变型属于本发明权利要求及其等同技术 的范围之内,则本发明也意图包含这些改动和变型在内。
