A heat-dissipation structure of a liquid crystal is disclosed. The heat dissipation structure comprises a light bar component having a circuit portion, the light bar component comprises a vertical plate and a horizontal plate, the vertical plate and the horizontal plate are formed by one-piece bending and are vertical to each other, and a plurality of LED light source modules are disposed on a surface of the vertical plate; and a back plate, the horizontal plate is disposed on the back plate. In the liquid crystal module and the heat dissipation structure, the bending light bar component is connected to the back plate. Compared with the traditional art, the liquid crystal module has narrower border, higher heat dissipation efficiency and longer life time.
