Abstract: PROBLEM TO BE SOLVED: To observe an excellent stereoscopic image having no feeling of incompatibility by making extinction shown by a specified expression including parallel luminance and vertical luminance in a linear polarization state satisfy a specified condition. SOLUTION: On a screen constituted of a lenticular lens sheet, at least either surface of which a lenticular lens is formed on, the extinction shown by the expression is >=15 dB when the parallel luminance and the vertical luminance in the linear polarization state are defined as Lh and Lv, respectively. In order to obtain a stereoscopic image having no feeling of incompatibility, it is desirable that the extinction obtained in the case of arranging the screen so that the axis of polarization of a 1st polarizing film may be a 45-degree direction is >=10 dB, more desirably, >=15 dB.
