An auto-stereoscopic type 3D-display including a transmissive display panel, a dynamic backlight module and a light guiding unit is provided. The dynamic backlight module is disposed at a side of the transmissive display panel and includes a plurality of bar-shaped light sources parallel to each other and a miniature lens. Each of the bar-shaped light sources includes an illumination region and the width of the illumination region is W1. The miniature lens is disposed between the transmissive display panel and the bar-shaped light sources. An image formed from each of the bar-shaped light sources is outside the miniature lens and has the width of W2, wherein W1/W2=n, and n is an integer greater than 1. In addition, the light guiding unit is disposed between the transmissive display panel and the miniature lens such that the image formed from each of the bar-shaped light sources is directed to different viewing domains.
