There is provided a transmission type screen that can suppress deterioration of image quality due to glare distortion of external light and the like that occurs on a screen surface while keeping a feeling (a glossy feeling of an image) as if a CRT-TV is directly viewed. The transmission type screenis arranged by combining a plurality of screen members (for example, a lenticular lens sheetand a Fresnel lens sheet), which realize various optical functions such as transmission, diffusion, condensing and the like of light, with each other. A smooth surface having a surface roughness Ra of 0 μm≦Ra≦0.5 μm is formed on the viewer side surface of a nearest-to-viewer side screen member (for example, the lenticular lens sheet) of the plurality of screen members, as well as the amount of warping D of the nearest-to-viewer side screen member (for example, the lenticular lens sheet) is −10 mm≦D≦15 mm.
