1. A stereoscopic display device, comprising:
a barrier panel on a display panel, the barrier panel including a plurality of barrier regions and a plurality of trigger regions, the plurality of barrier regions and the plurality of trigger regions having fixed positions in the barrier panel;
a display driver configured to drive the display panel; and
a barrier driver configured to form transmitting regions and blocking regions, which are regularly repeated in the barrier panel,
wherein in operation:
when a viewer is at a first viewing distance, a first number of the plurality of trigger regions includes a channel having intermediate gray value;
when the viewer is at a second viewing distance different than the first viewing distance, a second number of the plurality of trigger regions includes a channel having intermediate gray value that is different than the first number; and
the channels having intermediate gray value are disposed symmetrically with respect to a center of the barrier panel.
