    Abstract: A stereoscopic display device has a barrier panel. The barrier panel of the stereoscopic display device may include sequentially stacked first channel electrodes, second channel electrodes, and third channel electrodes. Each of the third channel electrodes may be disposed between the second channel electrodes. A distance between the third channel electrodes may be the same as a horizontal width of each third channel electrode. Each of the first channel electrodes may include a first region overlapping with an end portion of the second channel electrode, and a second region overlapping with an end portion of the third channel electrode facing the end portion of the second channel electrodes overlapping with the first region of adjacent first channel electrode. Thus, in the stereoscopic display device, the number of stacked layers of the channel electrodes may be minimized, a proper viewing range for a stereoscopic image may be smoothly moved.

    Abstract: Disclosed is a stereoscopic image display device which separates views from each other to reduce crosstalk and minimizes reduction in brightness due to decrease of an opening area of sub-pixels. The stereoscopic image display device includes a display panel including first and second sub-pixels arranged in parallel in the horizontal direction in each of regions formed by intersecting a plurality of gate lines and a plurality of data lines, openings for opening a part of each of the first and second sub-pixels in a light-shielding pattern configured to shield regions of the first and second sub-pixels other than the openings, and a parallax unit located on the display panel and including a plurality of lenses.

    Abstract: The disclosure relates to an autostereoscopic 3D display device for minimizing luminance difference in a view as well as a luminance difference between views. The 3D display device includes a display panel including pixels and a black matrix including openings exposing portions of the pixels, each of the pixels including a pixel electrode including a plurality of first fingers and a common electrode including a plurality of second fingers disposed between the first fingers, and a 3D optical plate disposed on a front surface or a rear surface of the display panel. At least two adjacent to each other in a horizontal direction have different shapes exposed by the plurality of openings.
