Claim:
1. A multi-view three-dimensional (3D) image display apparatus, comprising: a display panel in which pixels are arranged; a parallax separation means arranged so as to be spaced apart from the display panel; and a control unit configured to control formation of a modified common viewing zone in which viewing zones for each viewpoint pixel are arranged in a space, by viewpoint images created by the pixels of the display panel and the parallax separation means, wherein, in the modified common viewing zone, a first horizontal position of a viewing zone for each first viewpoint pixel created by a first pixel set on the display panel providing the viewpoint image and a first position of the parallax separation means corresponding to the first pixel set, and a second horizontal position of a viewing zone for each second viewpoint pixel created by a second pixel set adjacent to the first pixel set and a second position of the parallax separation means corresponding to the second pixel set, are not the same; wherein the parallax separation means is a parallax barrier or a lenticular lens, and a slit interval of the parallax barrier or a pitch T′ of the lenticular lens is larger than T of the multi-view 3D image display apparatus using a common viewing zone and smaller than T of a 3D image display apparatus employing an integral photography method; and wherein the slit interval of the parallax barrier or the pitch T′ of the lenticular lens is represented as the following Equation 6, where Wp denotes a pixel width, N denotes the number of viewpoints, E denotes a viewpoint interval, and δE denotes a horizontal position difference of a viewing zone created by a slit of an adjacent parallax barrier or the lenticular lens
