摘要： Disclosed is a display device including a micro-lens film which has a high fill-factor and a high luminance ratio and prevents generation of moiré. The micro-lens film (160) is configured to concentrate and diffuse light emitted from the light guide panel of the backlight, and includes a base film (162), a lens unit (166, 170, 180) formed at an upper surface of the base film, and a back-coating film (164, 172, 182) formed at a lower surface of the base film. The lens unit includes either unit block groups randomly arranged at the upper surface of the base film, each unit block group containing randomly arranged lenses (166a) having different sizes, and micro-beads (166b) randomly formed on surfaces of the lenses, or a plurality of lenses (170a) having a hexagonal bottom, and surfaces of the plurality of lenses are provided with irregular bosses, or regularly arranged lenses (180a), and micro-lenses (180b) subordinate to the respective lenses or formed between the lenses to minimize gaps between the regularly arranged lenses.
