PROBLEM TO BE SOLVED: To provide a stereoscopic display device having a wide horizontal viewing angle.SOLUTION: A polarizing plate 28 is configured to p-polarize a stereoscopic image light beam which has been spatially modulated in a first spatial modulation area P1 of a liquid crystal panel unit 24 based on a stereoscopic image signal, and s-polarize planar image light beams which have been spatially modulated in second and third spatial modulation areas P2 and P3, respectively based on planar image signals. The p-polarized light beam (p-polarized light L1) and the s-polarized light beams (s-polarized light L2, L3) polarized in the projector 6 are projected onto a screen 10. First and second polarized beam splitters 11 and 12 of the screen 10 are configured to transmit the p-polarized light L1 for a stereoscopic image, and refract the s-polarized light beams L2 and L3 for a planer image in a horizontal direction, respectively. While a stereoscopic image observable area A1 is secured at the front of the stereoscopic image display device, planar image observable areas A2 and A3 are secured on the external left and right sides of the area A1. |
