Abstract
A three dimensional display device includes an image display unit. The image display unit includes pixels having first sub-pixels corresponding to a left-eye image and second sub-pixels corresponding to a right-eye image. The three dimensional display device also includes a parallax barrier which is located proximately to the image display unit. The parallax barrier includes light interception portions and light transmission portions alternately and repeatedly arranged in a direction. The parallax barrier also includes color filters arranged between the light interception portions and the light transmission portions. The color filters control paths of lights from the pixels.
