A transmission screen exhibiting an image quality not degrading because of distortion due to reflection of outside light caused on the screen while maintaining the texture (the glossy texture of image) like the one that a direct-vision CRT-TV exhibits. The transmission screen (10) is composed of a combination of screen members (for example, a lenticlular lens sheet (11) and a Fresnel lens sheet (12)) realizing various optical functions such as light transmission, light diffusion, and light focusing. Out of the screen members, an observer-nearest-side screen member (for example, the lenticular lens sheet (11)) is disposed nearest to the observer. The observer-side surface of this screen member is so smooth to have a surface roughness Ra of 0mum<=Ra<=0.5mum, and the warp D of the observer-nearest-side screen member (for example, the lenticular lens sheet (11)) is -10mm<=D<=15mm.
