Abstract: A surface light source includes a light guide unit which allows two linear polarized lights having polarized planes perpendicular to each other to alternately exit from an exit surface in a direction substantially parallel with a normal line of the exit surface. A retardation element is arranged to face the exit surface. The retardation element has λ/2 retardation portions which give a phase difference of a ½ wavelength between ordinary light and abnormal light, and a plurality of non-retardation portions having substantially no phase difference alternately formed in a direction along the exit surface. A lens array is provided to face the light guide unit. The lens array allows light which has been transmitted through a λ/2 retardation portion to exit in a first inclined exiting direction, and allows light which has been transmitted through a non-retardation portion to exit in a second inclined exiting direction.
