It is an object to reduce 3D moiré and provide a higher-quality three dimensional image display device. The three dimensional image display device includes a display panel on which rows of pixels for right eye and rows of pixels for left eye are alternately arranged in a lateral direction, the display panel planarly displaying an image for three dimensional display, and a parallax forming liquid crystal panel for forming a parallax in an image for right eye and an image for left eye displayed by the display panel. Lateral direction center positions, which are vertexes of luminance in the lateral direction of an image for right eye and an image for left eye, where the image for three dimensional display is visually sensed through the parallax forming liquid crystal panel, are respectively positions shifted in the lateral direction in different positions in the screen longitudinal direction.
