A display device is provided to prevent a moir phenomenon and improve the light uniformity and the light exiting efficiency, by optimizing the linear arrangement angle of optical patterns formed on a prism film. A display device(1) comprises a light source(11), a light guiding plate(13), an LCD panel(20) having a plurality of pixels, and at least one prism film(17) interposed between the light guiding plate and the LCD panel. The prism film has optical patterns(19) linearly arranged. The linear arrangement direction of optical patterns of the prism film has a crossing angle of 40-50 degrees with respect to the pixel arrangement direction of pixels of the LCD panel. |
