An liquid crystal lens for improving a viewing angle and reducing crosstalk caused at the center of an electrode in a multi-view stereoscopic display fashion using an increased number of views per a viewing zone, and a stereoscopic display device using the same are disclosed. The display device includes a display panel having a plurality of sub-pixels in a matrix pattern to emit a 2-dimensional image signal, and an electrically-driven liquid crystal lens located at an upper surface of the display panel and including lens regions having a crosswise width equal to "m", a multiple of a crosswise width of a single sub-pixel and a lengthwise width equal to "n", a multiple of a lengthwise width of the sub-pixel, the lens regions of one line being shifted more than the lens regions of a following line by a distance "a" when viewed from a column direction.
