摘要： A liquid crystal display (LCD) is disclosed. The LCD comprises a front frame, a panel, a plastic frame and an optical film assembly. The panel comprises a display region and a non-display region, and the plastic frame and the front frame cooperate with each other to sandwich the non-display region of the panel therebetween. The plastic frame is formed with a V-groove(s) on a surface thereof that faces towards a light exiting surface of the optical film assembly. In this way, light rays traveling through the optical film assembly to the lower surface of the plastic frame are reflected by the V-groove(s) so as to be mostly concentrated onto the non-display region of the panel and then gradually attenuated to disappear. This can reduce the bright lines appearing in the display region of the panel and, consequently, improve the displaying effect of the whole LCD.
摘要翻译：公开了一种液晶显示器（LCD）。 LCD包括前框架，面板，塑料框架和光学膜组件。面板包括显示区域和非显示区域，并且塑料框架和前框架彼此协作以将面板的非显示区域夹在其间。塑料框架在其表面上形成有面向光学膜组件的光出射表面的V形槽。以这种方式，通过光学膜组件到塑料框架的下表面的光线被V形槽反射，以便大部分集中在面板的非显示区域上，然后逐渐衰减到消失。这可以减少出现在面板显示区域中的亮线，从而提高整个LCD的显示效果。
