A three-dimensional video recognition system comprises a display device, a front plate, and AS glasses. Each of the AS glasses includes a first lambda/4 plate, a first linear polarizing element, a liquid crystal cell, and a second linear polarizing element in this order from the outer surface side. The display device includes a third linear polarizing element on an observation surface side of the display device. The front plate has a second lambda/4 plate. Specific angles formed between a transmission axis of polarizing elements and lambda/4 plates are provided. |
