Disclosed is a liquid crystal display device that can simplify the assembly process of the liquid crystal display device and improve productivity. A sidewall of a shield case is extended to correspond to a sidewall of a top chassis. A burring is formed at the sidewall of the shield case to coupled with a screw, the burring corresponding to an engagement hole formed at the sidewall of the top chassis. Therefore, the production cost can be reduced by decreasing the parts of the liquid crystal display device, and the productivity can be improved due to simplification of the assembly process of the liquid crystal display device.
