The display panel 100 may be a thin film transistor (TFT) liquid crystal display (LCD) panel. In this case, the display panel 100 includes a first substrate having a first polarizing layer disposed on a rear surface thereof, a switching element layer disposed on a front surface thereof, and a second substrate having a color filter layer disposed on a rear surface thereof and a second polarizing layer disposed on a front surface thereof. And a liquid crystal layer interposed between the switching element layer and the color filter layer. TFT LCD panels are well known in the art and will not be described in detail.

Although not shown in FIG. 1, the stereoscopic image display device according to an exemplary embodiment may further include a backlight unit (not shown) for supplying light to the display panel 100. Since the backlight unit is known in the art, detailed description thereof is omitted.

Alternatively, the display panel 100 is not limited to the TFT LCD panel but may be formed of a plasma display panel or an organic light emitting diode display panel.

The barriers 220 are spaced apart by S from the pixels 110 of the display panel 100. Here, S is substantially the thickness of the base substrate 210. Accordingly, the thickness S of the base substrate 210 has a correlation as shown in Equation (1).

For example, when the pixel pitch P of the display panel 100 is 0.1 mm, the distance E between the left eye 510 and the right eye 520 of the observer 500 is 65 mm, and the viewing distance D is 650 mm, the base substrate ( The thickness S of 210 may be about 1 mm.
