Abstract
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.
