Disclosed is a 3D display device comprising a first polarizing film disposed at an observer-side, and a protective member, having a λ/4-function, disposed on an observer-side surface of the first polarizing film, wherein the first polarizing film is disposed so that an absorption axis thereof is along a direction of 45° or 135° with respect to a horizontal direction of a visual surface, the protective member is disposed so that a slow axis thereof is along a direction of 0° or 90° with respect to the horizontal direction of the visual surface, and an absolute value of Rth(550) of the protective member satisfies the following relation (I): 25 nm≦̸|Rth(550)|≦̸160 nm.  (I) |
