Claim 0:
1. A stereoscopic display device comprising:
a display layer for displaying multi-view images having at least three viewpoints into stereoscopic images;
a transparent layer arranged on one side of the display layer; and
a parallax barrier layer arranged on one side of the transparent layer and including a light blocking part for blocking light and a slit for transmitting the light,
wherein the stereoscopic images displayed on the display layer are sets of the multi-view images repeatedly arranged, and each of the sets of the multi-view images has at least one 2-dimensionally (2D) recognized α image to reduce dizziness of a viewer,
wherein a horizontal interval of the slit of the parallax barrier layer satisfies the following Equation 1:

S=a[(d−g)/d],  <Equation 1>

wherein in the Equation 1, d is a distance from the display layer to a human eye, g is a distance between the display layer and the parallax barrier, a is ½ horizontal pitch of an R (red) element forming one pixel unit in the stereoscopic image, and S is the horizontal interval (width) of the slit of the parallax barrier layer.
