Abstract

The invention discloses a liquid crystal display device, which comprises a liquid crystal panel and a frame for fixing the liquid crystal panel. Contact surfaces of the frame and the liquid crystal panel are respectively provided with a hole or a convex block, the hole is matched with the convex block, and the frame and the liquid crystal panel are fixed via embedment of the convex block into the hole. Since the contact surfaces of the liquid crystal panel and the frame are provided with the convex block and the hole, the liquid crystal panel can be fixed in case of vibration due to horizontal limitation as a result of the embedment of the convex block into the hole, and the horizontal swinging of the liquid crystal panel can be avoided. Therefore, the liquid crystal panel cannot fall off a front frame to be broken even if a narrow frame is used, and the positioning performance of the liquid crystal panel is greatly improved.
