Abstract
This invention provides a stereoscopic image display apparatus, which allows the observer to satisfactorily observe a plurality of stereoscopic images from a plurality of positions by appropriately setting individual elements such as two lenticular lenses having refractive power in orthogonal directions, a mask pattern on which aperture portions and light-shielding portions are arranged at predetermined pitches, a display for dividing a plurality of parallax images into a large number of horizontal stripe-shaped parallax images and displaying the plurality of horizontal stripe-shaped parallax images at predetermined pitches in the vertical direction, and the like, upon observing a stereoscopic image using the lenticular lenses.
