The present invention relates to a polarizing liquid crystal film having no alignment layer and a method for manufacturing the same, a light guide plate integrated with the polarizing liquid crystal film, and a backlight unit. The polarizing liquid crystal film of the present invention includes an adhesive layer, a liquid crystal layer aligned on one side of the adhesive layer, and a protection film arranged on an opposite side of the adhesive layer to protect the liquid crystal layer. Further, the method for manufacturing a polarizing liquid crystal film includes preparing a liquid crystal alignment film, aligning liquid crystal on the liquid crystal alignment film, providing an adhesive layer on the liquid crystal, attaching a protection film protecting the liquid crystal on the adhesive layer, and exfoliating the liquid crystal alignment film. Furthermore, there is provided a light guide plate integrated with the polarizing liquid crystal film and a backlight unit including the same.
