A screen having a wide viewing angle and a projection television including the screen are provided. The screen includes a Fresnel lens sheet for converting incident light into near-parallel light, a lenticular lens sheet including a horizontal array of vertical cylindrical lenses for horizontally emitting light, in which vertical black stripes are formed in parallel on connection portions for the cylindrical lenses, and a light diffusion film including a vertical array of horizontal cylindrical lenses for vertically emitting light, in which horizontal black stripes are formed in parallel on connection portions for the cylindrical lenses. In particular, the screen has a wide vertical viewing angle and a high contrast ratio, thereby providing a high definition image.
