Abstract
A three-dimensional image display apparatus displays element images each composed of a set of parallax component images. An exit pupil array is located opposite the display surface. Exit pupils of the array correspond to the respective element images. The horizontal pitch of the exit pupils or an integral multiple of the horizontal pitch is set equal or slightly smaller than an integral multiple of the horizontal pitch of pixels. The parallax component images are oriented in different directions via the exit pupil. Principal beams from the parallax component images via the exit pupils are emitted substantially parallel to one another. The element image contains substantially the same parallax image component in two pixel areas in which two adjacent parallax image components are otherwise displayed. The same parallax image component is oriented in different directions via the corresponding exit pupil.
