Three-dimensional image display device, portable terminal device, display panel and fly eye lens

摘要

In a three-dimensional image display device for displaying color three-dimensional images, a fly eye lens, a display panel, and a light source are provided in this order from the observer side. A display panel has four pixels arrayed in a (2×2) matrix correlated with one lens element of the fly eye lens. In the event that j is a natural number, a pixel magnifying projection width e in a second direction is set in a range of the following expression according to mean interpupillary distance Y of the observers.;e3≠Y2×j

1. A three-dimensional image display device comprising:
a display panel on which a plurality of pixels colored in a plurality of colors are arrayed in a first direction, and a second direction orthogonal to said first direction, in matrix fashion; and an optical unit for distributing light emitted from the pixels arrayed in said first direction along said first direction, and also for distributing light emitted from the pixels arrayed in said second direction along said second direction, wherein said optical unit, to an observer if a direction from a right eye to a left eye of the observer is the same as said first direction, distributes light for the right eye emitted from the pixels arrayed in said first direction to the right eye and light for the left eye emitted from the pixels arrayed in said first direction to the left eye, and to the observer, if the direction from the right eye to the left eye of the observer is the same as said second direction, distributes light for the right eye emitted from the pixels arrayed in said second direction to the right eye and light for the left eye emitted from the pixels arrayed in said second direction to the left eye, the array pitch of said pixels in said first direction and the array pitch of said pixels in said second direction are equal to each other, said display panel has a plurality of pixel matrixes each made up of a plurality of pixels having colors different from each other said plurality of pixels being arrayed adjacent to each other in said first direction and in said second direction in matrix fashion, so that a pixel of another pixel matrix is not present between said plurality of pixels included in each of said plurality of pixel matrixes, said optical unit is a fly eye lens that has a plurality of optical elements, in matrix fashion, that distribute light along said first direction and said second direction, each of said plurality of optical elements being correspondingly provided to one pixel matrix of said plurality of pixel matrixes, said display panel has a plurality of display units each made up of said plurality of pixel matrixes arrayed adjacent to each other in said first direction and said second direction in matrix fashion, so that said plurality of pixel matrixes do not overlap each other, and in each of said plurality of display units, pixel arrays arrayed in said first direction and pixel arrays arrayed in said second direction each include therein pixels of all the plurality of colors, respective colors of said pixels in each of said pixel arrays arrayed in said first and second directions being different from one another.
