 本发明的最佳实施方式
以下各实施例的说明是参考附加的图式，用以例示本发明可用以实施的特定实施例。本发明所提到的方向用语，例如「上」、「下」、「前」、「后」、「左」、「右」、「内」、「外」、「侧面」等，仅是参考附加图式的方向。因此，使用的方向用语是用以说明及理解本发明，而非用以限制本发明。在图中，结构相似的单元是以相同标号表示。
请参照图2，图2为本发明第一种液晶显示面板的结构示意图。
如图2所示，本发明的液晶显示面板10包括：第一基板20、液晶层，第二基板30；所述第一基板20可以为彩膜基板、所述第二基板30可以为阵列基板。
所述第一基板20包括第一衬底21、第一透明导电层22，所述第一透明导电层22位于所述第一基板20的内侧，所述内侧为靠近液晶层的一侧，所述第一透明导电层22用于导入蓄积在所述第一基板上的第一极性的电荷（譬如负极性的残留电荷）；所述液晶层位于所述第一基板20和第二基板30之间；以及
所述第二基板30与所述第一基板20相对设置，其包括：第二衬底31、第二透明导电层32，所述第二透明导电层32位于所述第二基板30的内侧；所述第二透明导电层用于导入蓄积在所述第二基板上的第二极性的电荷（譬如正极性的残留电荷）；
在所述第一基板20上设置有连接部件23，当然所述连接部件23也可以位于所述第二基板30上。当在按压所述显示面板10时，如图3所示，所述连接部件23使所述第一透明导电层22和所述第二透明导电层32电性连接。当然，所述连接部件23不限于图2所示的形式。
当按压本发明的液晶显示面板10时，所述连接部件23接触第二基板30，即第一透明导电层22和第二透明导电层32电性连接，从而使积累在第一基板20和第二基板30上的正负残留电荷产生中和，避免了残像产生，提高显示效果和质量。
在所述第一基板20上还可设置上有黑色矩阵(图中未示出)、色阻层(图中未示出)以及第三透明导电层(图中未示出)，所述色阻层位于所述第一衬底21上，所述色阻层包括红色彩膜、绿色彩膜、蓝色彩膜；所述黑色矩阵位于相邻两个彩膜色阻之间，所述第三透明导电层位于所述色阻层上，所述第三透明导电层包括公共电极，所述第一透明导电层位于所述第三透明导电层的外侧（即所述第一透明导电层更靠近液晶层），在所述第一透明导电层和所述第三透明导电层之间还可设置有第一绝缘层。
在所述第二基板30上还可设置上开关阵列层(图中未示出)以及第四透明导电层(图中未示出)，所述开关阵列层位于所述第二衬底31上，所述开关阵列层包括多个薄膜晶体管(图中未示出)；所述第四透明导电层位于所述开关阵列层上，所述第四透明导电层包括像素电极，所述第二透明导电层位于所述第四透明导电层的外侧（即所述第二透明导电层更靠近液晶层），在所述第二透明导电层和所述第四透明导电层之间还可设置有第二绝缘层。
由于上述黑色矩阵、色阻层、以及以公共电极为例的第三透明导电层、开关阵列层以及以像素电极为例的第四透明导电层均属于现有技术范畴，在此不作进一步说明。
优选地，如图2所示，所述连接部件23为一个凸起物，该凸起物可位于第一基板20或者第二基板30上。当所述凸起物位于所述第一基板20上时，所述第一透明导电层22延伸至覆盖所述凸起物。
当然，所述凸起物也可以位于所述第二基板30上时，此时所述第二透明导电层32延伸至覆盖所述凸起物。
优选地，所述凸起物23的材料为树脂材料，由于树脂材料是液晶显示面板的常用材料，因此采用该材料可以简化生产过程，降低成本。
优选地，所述液晶显示面板输入有图像信号，所述显示面板包括显示区域，所述显示区域用于对输入的图像信号进行显示；所述连接部件23位于所述显示区域外，以防止所述连接部件影响板的开口率。所述连接部件也可以位于显示区域，所述连接部件可设置在与黑色矩阵对应的位置，优选与黑色矩阵正对的位置。当所述连接部件23为凸起物时，所述凸起物23的材料优选为透明的树脂材料。
优选的，所述连接部件23可以与液晶显示面板中的间隔物（图中未示出）在同一制程中制得，从而无需额外增加制造工序和成本；所述间隔物用于维持第一基板和第二基板之间保持一定间距。
请参照图4，图4为本发明第二种液晶显示面板的结构示意图。
如图4所示，所述液晶显示面板10在第一基板20和第二基板30上各设置有凸起物，即所述连接部件包括相对设置的第一凸起物24和第二凸起物34；所述第一凸起物24设置在所述第一基板20上；所述第一透明导电层25位于所述第一凸起物24上以及未被所述第一凸起物24覆盖的所述第一基板20的内侧；
所述第二透明导电层35位于所述第二凸起物34上以及未被所述第二凸起物34覆盖的所述第二基板30的内侧。
当按压所述显示面板10时，如图5所示，所述第一凸起物24和所述第二凸起34物接触，从而使所述第一透明导电层25和所述第二透明导电层35电性连接。
当然所述第一凸起物24的第二凸起物34的形状不限于图4所示的结构，其他能实现本发明目的的结构，同样也适用于本发明。
譬如在人使用手机或平板电脑等显示设备时，手指触摸带来的压力，会使上、下凸起物接触；上、下基板的正、负电荷可以被导通至凸起物上的导电层发生正、负电荷的中和。
由于本发明的液晶显示面板，分别在两个基板各设置一凸起物，在按压时，使得两个透明导电层电性连接，可以使积累在第一基板和第二基板上的正负残留电荷产生中和，从而避免了残像产生，提高显示效果和质量。
本发明还提供一种液晶显示装置，其包括背光模块（图中未示出）和上述实施例中的液晶显示面板10。
本实施例中的液晶显示面板10如图2至图5所示，其具体结构与前述实施例完全相同，在此不再赘述。
本发明的液晶显示面板及装置，通过在两个基板内侧增加导电层，并在基板之间增加连接部件，能够在按压面板时，使得两个导电层电性连接，进而使得残留在基板上的电荷离子中和，避免了残像的产生，提高显了示效果。
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。
