Patent ID: 7714946

Claim:
A stereoscopic display device comprising: a display panel having a plurality of sub-pixels arranged in a matrix pattern and adapted to emit a 2-dimensional image signal; and an electrically-driven liquid crystal lens located at an upper surface of the display panel and consisting of lens regions each 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 when viewed in a column direction by a shift distance “a”, wherein the electrically-driven liquid crystal lens comprises: first and second substrates arranged opposite each other; first electrodes formed on the first substrate to correspond to edges of the respective lens regions on the first substrate; second electrodes formed, about the respective first electrodes, on the first substrate underneath the first electrodes and placed between centers of the neighboring left and right lens regions; a black matrix layer formed along boundaries of the lens regions of different lines in a column direction; a third electrode formed throughout the second substrate; and a liquid crystal layer interposed between the first substrate and the second substrate.
