Claim 1:
2. 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 the number of multi-viewpoints of the multi-view image displayed on the display layer satisfies the following Equation 2:

e=a[(d−g)/g],  <Equation 2>

that is, q≈65 mm/e,
wherein in the Equation 2, d is a distance from the display layer and a human eye, g is a distance between the display layer and the parallax barrier, a is H horizontal pitch of an R element forming one pixel unit in the stereoscopic image, e is a width of a horizontal view field that can be seen through compared to the size of one unit element (based on one eye), and q is the required number of the multi-viewpoints (rounding up to the nearest decimal point).
