A three-dimensional display device having a capacity to display three-dimensional images with a resolution level of two-dimensional images. The three-dimensional display device includes an image display unit where left sub-pixels corresponding to a left-eye image part and right sub-pixels corresponding to a right-eye image part are formed in a pattern in a sub-pixel array having rows and columns respectively arranged in a row direction and a column direction. A parallax barrier, which is adjacent to the image display unit, has a plurality of light interception portions and light transmission portions. Centers of the light transmission portions in the column direction of the sub-pixel array are offset from each other in the row direction of the sub-pixel array.
