The invention relates to a liquid crystal display (LCD) which comprises an LCD panel, a back light module, an optical film layer, an upper cover plate and a bottom back plate, wherein a light guide plate, the optical film layer and the LCD panel in the back light module are fixed together by adhesive layers. The light guide plate, the optical film layer and the LCD panel are fixed together by theadhesive layers, so that the whole strength of the LCD is improved, and the problems that the flatness is not easily guaranteed, and installation and fixation are more difficult when a thin light guide plate is in use can be solved; and furthermore, the assembly of the back light module and the assembly between the LCD panel and multiple peripheral parts can be manufactured in an integral way, sothat integration of production can be realized.
