  "textContent": "The present invention provides a method of displaying, in color, information accompanying rotation in a device having a rotating member, comprising disposing a first polarizing film, a printed film, a retardation film, and a second polarizing film approximately perpendicularly to the direction of the rotational axis of the rotation; with the first polarizing film, retardation film, and second polarizing film being the sequence of disposition; and with one or two films selected from among the first polarizing film, the retardation film, and the second polarizing film being caused to rotate in a manner accompanying rotation of the rotating member. The method of the present invention affords inexpensive installation, maintenance, and use; good energy efficiency; and complex color display in a greater number of colors.",
