    Abstract: A stereoscopic display device having a barrier panel is provided. The barrier panel can include channel electrodes to form transmitting regions and blocking regions in an active area, and link lines to provide a signal to the channel electrodes. The stereoscopic display device can include a display driver driving a display panel; a barrier panel on the display panel, the barrier panel including channel electrodes across an active area, and link lines disposed outside the active area; and a barrier driver controlling the channel electrodes through the link lines, wherein the number of the link lines in which each channel electrode crosses, is constant. Thus, in the stereoscopic display device, a dark spot due to a load deviation of the channel electrodes can be prevented.

    Abstract: A parallax barrier according to an example can include a first substrate and a second substrate, a liquid crystal layer between the first substrate and second substrate, at least one insulating layer on the first substrate, a first electrode on the second substrate, a second electrode and a third electrode on the insulating layer to generate electric field in order to transmit and block selectively an image, a plurality of first spacers on the first substrate, and a plurality of second spacers on the second substrate. The first spacers and the second spacers can be formed in regions corresponding to each to maintain gap between the first substrate and the second substrate. Further, the first spacers can be spaced apart from the corresponding second spacers by a predetermined distance.

    Abstract: A stereoscopic display device having a barrier panel is provided. The barrier panel may include lower channels, a channel insulating layer and upper channels, which are sequentially stacked on a barrier panel. The lower channels may be disposed between the upper channels. Each of the lower channels may include a first sub-channel, a second sub-channel and a lower insulating layer. The lower insulating layer may be spaced away from the first sub-channel. The second sub-channel may be connected to an end region of the first sub-channel facing the upper channels. The second sub-channel may be extended along a side wall of the lower insulating layer facing the first sub-channel. Thus, in the stereoscopic display device according to the embodiment of the present disclosure, a distance between the lower channels may be minimized. Therefore, in the stereoscopic display device according to the embodiments of the present disclosure, a proper viewing range of the stereoscopic image may be moved according to the location of the viewer, naturally.
