Claim:
1. A stereoscopic display device, comprising: a base substrate transmitting an incident beam of a light source; a three-dimensional effect forming part on a first surface of the base substrate; and a driving part to rotate the light source, wherein the three-dimensional effect forming part has a pattern, the pattern having multiple pattern units arranged in a first direction, each of the pattern units having an inclined surface having an inclination angle with respect to the first surface, wherein when an incident beam is incident to a central portion of the pattern, the pattern guides the incident beam in a first surface direction toward which the first surface looks or a second surface direction toward which a second surface opposite to the first surface looks, thereby displaying a line-shaped beam having a three-dimensional effect in a first path resulting a pattern arrangement direction, wherein the light source is disposed in the central portion of the pattern, and the driving part rotates the light source at the central portion so as to rotate the line-shaped beam in an extending direction of the multiple pattern units.
