【技术领域】
本发明涉及液晶显示技术领域，特别是涉及一种液晶显示装置。
【背景技术】
传统的液晶显示装置一般包括前框、胶框、背框架、液晶面板、光学膜片、导光板等，前框、胶框与背框架一同夹持固定液晶面板，以保护液晶面板。
由于整体式背框架生产成本高且重量大，当前的液晶显示装置一般采用拼接式背框架。对于拼接式背框架，由于入光侧的光源发热量大，为提高装置的使用寿命，必须采取散热措施以及时散发光源所发出的热量，现有技术中一般采用散热性能较强的材料作为入光侧的拼接件。
当使用铝挤作为入光侧的拼接件时，前框需要与铝挤配合以固定保护液晶面板，由于铝挤不易加工卡钩结构，在固定光源时，一般采用螺丝锁附的方式。采用螺丝锁附进行固定时，由于需要避开光源，螺丝孔的位置选择困难。

在本实施例中，通过在主拼接115件的外侧设置第一锁附孔（图未示）、第二侧壁128上设置与第一锁附孔相对应的第二锁附孔300，采用螺丝锁附或铆钉使得第二侧壁128固定在主拼接件115上。
此外，应理解，本发明铝挤和角落件的卡合还有其他实施方式，例如：
另一实施例中，图7所示液晶显示装置200的结构单元与图5所示液晶显示装置100相同，不同之处在于，铝挤214包括在侧壁218的高度方向上间隔设置的第一延伸部216和第二延伸部217，第一延伸部216和第二延伸部217分别自铝挤214的侧壁218的外侧向外延伸，且第一延伸部216、第二延伸部217和铝挤214的侧壁218之间形成的导槽219呈梯形；接合部226自第一侧壁227朝向导槽219垂直延伸，且接合部226呈梯形，以卡合在导槽219中。本实施例液晶显示装置200装配原理与上述实施例相同，此处不再赘述。
综上所述，本发明采用分设在液晶模组的四个角的角落件组成的前框，并通过角落件上设置接合部对应卡合在铝挤拼接式背框架的导槽内，实现前框与铝挤的固定，进而解决了铝挤作为入光侧拼接件固定前框与液晶模组时，为避开光源导致的螺丝孔位置选择难的问题；另一方面，采用四个角落件作为前框，使得前框的结构简单且成本较低。
以上所述仅为本发明的实施方式，并非因此限制本发明的专利范围，凡是利用本发明说明书及附图内容所作的等效结构或等效流程变换，或直接或间接运用在其他相关的技术领域，均同理包括在本发明的专利保护范围内。
