An exemplary liquid crystal display (1) includes a liquid crystal panel (13) and a frame (12) receiving the liquid crystal panel. The frame includes a stopper (126) configured for blocking the liquid crystal panel from being pulled up. The liquid crystal display further includes a light guide plate (17) having a light incident surface (172). Light beams emitted from a plurality of point illuminators (18) enter the light incident surface (172) of the light guide plate 17, and the desired optical performance of liquid crystal display is stably maintained.
