Abstract
An electronically-controlled viewing angle switching device, including a liquid crystal layer, a first electrode, a second electrode, a plurality of first insulation patterns, and a plurality of second insulation patterns is provided. The first electrode and the second electrode are respectively located at a first side and a second side of the liquid crystal layer. The first insulation patterns are located at the first side of the liquid crystal layer. The second insulation patterns are located at the second side of the liquid crystal layer. Each of the first insulation patterns is at least partially overlapped with the corresponding second insulation pattern. A display device adopting the electronically-controlled viewing angle switching device is also provided. The electronically-controlled viewing angle switching device and the display device provide a good anti-peed effect from a side viewing angle.
