Display device for transportation means

摘要

A jet propulsion boat is equipped with a liquid crystal display unit displaying operation information. An ordinary movement of the jet propulsion boat is regarded as an ordinary state. When the need arises for abruptly reducing the speed of the transportation means or abruptly changing the direction of the transportation means, and the like it is regarded as a non-ordinary state. The liquid crystal display unit is caused to reverse a white-and-black display thereof when the jet propulsion boat shifts from the ordinary state to the non-ordinary state. It is possible to sensitively and directly notify the driver that the transportation means is in a non-ordinary state. As a result, it becomes easier to recognize that the jet propulsion boat is in a non-ordinary state.
