The present invention discloses a stereoscopic display device with a parallax barrier. The parallax barrier includes: a first substrate; a plurality of first electrodes parallel to each other and stretching in one direction on the first substrate; a transparent insulation layer between the first substrate and the first electrodes; a plurality of second electrodes parallel to each other and stretching in one direction on the opposite side against the first electrodes; a common electrode between the second substrate and the transparent insulation layer; and a liquid crystal layer between the common electrode and the second electrodes. In particular, the plurality of first electrodes and second electrodes interlace with each other and each contains partial overlapping in the vertical direction.
