Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a three-dimensional display device that can freely change a display position of a three-dimensional image having a light amount increased and optical characteristics thereof enhanced.SOLUTION: A three-dimensional display device 10" comprises: a light guide plate 1; two light sources 2a and 2b that are provided on two light incidence surfaces Sina and Sinb of the light guide plate; a single-sided irregular shape triangular prism sheet 3 that is provided on a light emission surface side Sout1 of the light guide plate 1; a transmission-type liquid crystal display panel 4 that is provided on a light emission surface Sout3 of the light guide plate; a synchronization driving circuit 5 that displays a parallax image on the display panel 4 in synchronization with two light sources 2a and 2b; and a total control circuits 6. A phase difference plate 8 is provided that rotates a main deflection direction of a single-sided irregular shape triangular prism sheet 3' at a predetermined angle. The phase difference plate 8 is inserted between the single-sided irregular shape triangular prism sheet 3' and an optical modulation part 7. An adhesion layer 9 is provided between the single-sided irregular shape triangular prism sheet 3' and the phase difference plate 8, between the phase difference plate 8 and the optical modulation part 7, and between the optical modulation part 7 and the transmission-type liquid crystal display panel 4.
