Abstract
Provided is a work vehicle such as a hydraulic shovel comprising a monitoring unit that monitors the surroundings of the work vehicle, and a display unit that displays an image acquired by the monitoring unit. The display unit has an image display area in which the image is displayed, and an alarm information display area in which alarm information indicating the presence of an obstacle is displayed when the monitoring unit detects the presence of the obstacle. In the display unit, the alarm information display area is located outside the image display area.
