Abstract: Disclosed are a display screen of an image display system capable of displaying a 3D (three-dimensional) image and providing an image with a high contrast ratio in a bright room and a method for manufacturing the same. The display screen includes: a Fresnel lens layer; a reflective layer formed the light-exit surface of the Fresnel lens layer to reflect image light; and a protection layer formed on the light-incident surface of the Fresnel lens layer, wherein one surface of the protection layer may have an embossed pattern.
