Abstract: In a three dimensional display device of a parallax barrier system in which an IPS-mode liquid crystal display panel is used as a liquid crystal display panel for displaying images and a TN-mode liquid crystal panel is used as a parallax barrier panel, alignment axes of a counter substrate and a barrier substrate constituting the parallax barrier panel are set to 45 degrees and 135 degrees, respectively, with respect to a horizontal direction of a screen. This allows an improvement in the viewing angle characteristics of the parallax barrier panel and an improvement in the viewing characteristics of the overall three dimensional display device of the parallax barrier system. Thus, even when the line of sight moves, crosstalk between an image for a right eye and an image for a left eye can be prevented thereby allowing a viewer to recognize excellent three dimensional images.
