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 stereoscopic display device having a barrier panel is provided. The barrier panel may include channel electrodes across an active area. Each of the channel electrodes may include an end portion connected to corresponding link line. Each of the channel electrodes may be connected to the link line same as (n+1)th channel electrode from the channel electrode. The barrier panel may further include connecting lines to connect between opposite end portions of the channel electrode which are connected to the same link line. Thus, in the stereoscopic display device, the number of the wires extending along an edge of the active area may be reduced.

Abstract: A stereoscopic display device including a barrier panel is provided. When a viewing distance of a viewer is out of the proper range, the stereoscopic display device may shift the blocking regions and the transmitting regions of the barrier panel. The stereoscopic display device may maintain the ratio of channels located within a barrier blocking region and a barrier transmitting region of the barrier panel by using the channels disposed within trigger regions of the barrier panel. Thus, the stereoscopic display device may provide a stereoscopic image of good quality to the viewer located at a region being out of the proper range.

Abstract: A stereoscopic display apparatus is disclosed. In the stereoscopic display apparatus, each unit pixel of a display panel includes a first transparent region. A barrier panel on the display panel may include second transparent regions overlapping with the first transparent region of each unit pixel. Thus, in the stereoscopic display apparatus, the transparency may be improved without the quality deterioration of a stereoscopic image.

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.
