Claim 3:
4. 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 in a case in which a pixel structure of the display layer is an RG-BW (red, green-blue, white) pentile subpixel structure, an angle of the slit of the parallax barrier layer satisfies the following Equation 4:

θ2=arctan[a/(2N2*b)]*180/π,  <Equation 4>

wherein in the Equation 4, θ1 means an angle between the slit and a line vertically connecting an RGB subpixels in a pixel arrangement of the display layer, a is ½ horizontal pitch of an R element forming one pixel unit in the stereoscopic image, b is ½ vertical pitch of the R element forming the one pixel unit of the stereoscopic image, and N2 is a natural number of 2 or more, namely, an integer less than or equal to the number of multi-points.
