PROBLEM TO BE SOLVED: To solve a problem wherein the presence or absence of stability at the time is difficult to be intuitively or instantaneously recognized in a conventional overturning prevention device or display device. SOLUTION: This display device is provided with jack reaction force detection means 25 for detecting jack reaction force of an outrigger 3, an outrigger extension width detection means 20 for detecting an extension width of the outrigger 3, an integrated center of gravity position arithmetic means 41 for calculating an integrated center of gravity position 56 in plane view of a working vehicle from a jack reaction force signal and an outrigger extension width signal, an image data arithmetic means 45 for calculating image data of the integrated center of gravity position 56 in relation to a jack position from the outrigger extension width detection means 20 and the integrated center of gravity position arithmetic means 41, and an image display device 46 for displaying the image of the integrated center of gravity position 56 in relation to the jack position on a screen by a signal from the image data arithmetic means 45.
