Description

液晶显示面板及液晶显示装置 技术领域
本发明涉及显示技术领域，特别是涉及液晶显示面板及液晶显示装置。
 背景技术
在液晶显示的发展趋势中，随着量子点在LCD中的应用，比如超薄LCD、极端环境使用特种LCD、柔性显示等新型显示的驱动下，内置偏光片的需求变得更加强烈，使得贴覆型内置染料偏光片被广泛应用。贴覆型内置染料偏光片采用拉伸型的染料偏光膜，是通过胶膜贴覆在基板内侧，再制作透明导电膜、配向膜、与对侧基板一起对组以及在两基板中间分布液晶，得到液晶显示面板。贴覆型内置染料偏光具有偏振度高、信赖性好的优点。
 技术问题
但是，由于拉伸型的偏光膜贴覆在基板内侧后，在后续热制程中容易发生收缩，尤其是在受力不平衡的边缘处，当胶膜与偏光膜有较好的附着性以及变形匹配性时，显示面板的边缘出现褶皱，当匹配性不佳时，则显示面板的边缘出现严重的翘起，翘起部分的中间出现气泡。即便是在匹配性最佳的情况下，显示面板的边缘也会出现褶皱，褶皱将接触到对侧基板（阵列基板），由于对侧基板上分布有透明导电膜（ITO），且内置偏光膜侧的基板（彩膜基板）上也分布整面的透明导电膜，当褶皱接触到对侧基板时，导致两侧基板的ITO相导通，当两侧基板的ITO导通时，则无法形成使液晶偏转的电势差，导致显示面板无法显示。

请参照图2至4，图2为本发明实施例一的液晶显示装置的结构示意图。
本实施例的液晶显示装置包括液晶显示面板，液晶显示面板包括相对设置彩膜基板20、阵列基板10、设于所述彩膜基板20与阵列基板10之间的液晶层30。其中所述液晶显示面板具有显示区域。
所述阵列基板10包括第二衬底11、以及依次位于第二衬底11上的第二染料偏光膜12、开关阵列层13及第二透明导电层14。

请参照图5至7，图5为本发明实施例二的液晶显示装置的结构示意图。
本实施例与上一实施例的区别在于，本实施例中的所述第一透明导电层24还设于所述色阻层23的外侧部分的下方，所述外侧部分与所述框胶25的外侧的区域的位置对应。
结合图6和7，其中图7中的虚线框表示框胶25的外周缘，所述第一透明导电层24包括第一部分241和第二部分242，所述第一部分241与所述框胶25的内侧的区域的位置对应，所述第二部分242与所述框胶25的外侧的区域的位置对应。所述框胶25的内侧的区域为所述框胶25的内周缘251限定的区域。所述框胶25的外侧的区域为所述框胶25的外周缘252限定的区域。也即仅在与所述框胶25的位置对应的色阻层23的下方未设置第一透明导电层24。第一部分241和第二部分242的间隙处的形状与框胶25的形状相同。
可见本实施例的第一透明导电层24在框胶25内和外形成两个分离的部分，可有效避免显示面板的边缘出现褶皱时，与显示区域对应的上下基板的透明导电层导通。
本实施例的在第一透明导电层24图案化处理过程中所使用的掩膜板可与制作框胶的掩膜板相同或者不同。
由于本发明的显示面板采用内置偏光膜的结构，不仅可以减小显示面板的厚度，且当环境中温度较高时，内置偏光膜不容易发生翘曲，同时染料偏振子比传统碘系偏振子更耐高温，不容易因高温而失效；另外由于将偏光膜的断面保护在框胶内，可防止偏光膜受潮吸水影响偏振效果。
可以理解的，返回图2或4，本发明的液晶显示装置还包括设于所述阵列基板10远离液晶层30一侧的导光板40以及设于所述导光板40左侧的背光源50。当然，背光源50也可设于所述导光板40的右侧。
本发明的液晶显示面板及液晶显示装置，通过在第一染料偏光膜的内侧部分的下方设置第一透明导电层，从而避免显示面板的边缘出现褶皱时，上下基板的透明导电层导通导致显示面板无法显示的问题。
综上所述，虽然本发明已以优选实施例揭露如上，但上述优选实施例并非用以限制本发明，本领域的普通技术人员，在不脱离本发明的精神和范围内，均可作各种更动与润饰，因此本发明的保护范围以权利要求界定的范围为准。
