Abstract
An image display device of the present invention includes: a display element having pixels which are arranged in columns and rows and are grouped into a plurality of right eye pixel groups and a plurality of left eye pixel groups, each of the right eye pixel groups and the left eye pixel groups including at least one pixel; a driver which supplies driving signals to the right eye pixel groups and the left eye pixel groups independently; an optical member for making a polarization state of light exiting from the right eye pixel groups different from a polarization state of light exiting from the left eye pixel groups; and an array of microlenses which is disposed in the vicinity of the optical member, wherein each of the microlenses collimates light exiting from a corresponding one group of the right eye pixel groups and the left eye pixel groups.
