具体地，所述导光板400为靠近所述背板200设置，所述光学膜片500为靠近所述液晶面板300设置，在所述导光板和所述背板之间还设有反射片。
本实施例中，导光板400为靠近所述背板200设置，所述光学膜片500为靠近所述液晶面板300设置，可将由光源发出的光均匀地投射到液晶面板300上；同时，在所述导光板400和所述背板200之间还设置有反射片700，可将导光板400底面露出的光反射回导光板400中，提高光的利用率。
请参照图7，优选地，所述背板200与所述固定部120通过螺钉800连接。
作为一种优选实施例，由于顶侧的凹槽121用于配合凸台410以固定导光板400，导致中框100与背板200粘胶面减少，可能出现背板200、中框100粘合不牢易脱离，故需在凹槽121处的附近增加螺钉800固定，从背板200侧锁附固定，使装配结构简单可靠。
综上，本无边框液晶显示模组通过上述结构和组件的尺寸控制，能在无边框结构的前提下，将厚度控制在5.0~5.9mm之内，使产品更加轻薄，更加具有市场竞争力。
本申请还提供一种液晶电视，所述液晶电视包括如上述所述的无边框液晶显示模组。该无边框液晶显示模组的具体结构参照上述实施例，由于本液晶电视采用了上述所有实施例的全部技术方案，因此至少具有上述实施例的技术方案所带来的所有有益效果，在此不再一一赘述。
以上所述仅为本申请的优选实施例，并非因此限制本申请的专利范围，凡是在本申请的构思下，利用本申请说明书及附图内容所作的等效结构变换，或直接/间接运用在其他相关的技术领域均包括在本申请的专利保护范围内。
