摘要： There is disclosed a display device making it possible to call effective attention in a use situation where unbalanced passenger load occurs between left and right lanes of a passenger conveyor. This display device includes a first display unit (7A) positioned on the left and a second display unit (7B) positioned on the right toward the passenger conveyor at a boarding (1), a control device (20) to control the first display unit (7A) and the second display unit (7B), and passenger detection (8A, 8B) to detect passengers stepping on the passenger conveyor. The first display unit (7A) and the second display unit (7B) display images representing information to passengers. The passengers pass between the first display unit (7A) and the second display unit (7B) and step on the passenger conveyor. The control device (20) estimates a state of congestion and a state of passengers gathering on only one lane in the passenger conveyor, based on detection signals from the passenger detection means (8A, 8B), and sets an image to be displayed by the first display unit (7A) and an image to be displayed by the second display device (7B) independently, depending on the state of congestion and the state of passengers gathering on only one lane.
