摘要

There have been many studies on letter sizes and contrast etc. in order to improve visibility of in-vehicle display. This paper will be reported the results of verification for aging visibility for LED colored light with different wavelengths. As a result of the experiment, it was clarified that use of colored light on the short-wavelength side is effective for visibility on the elderly.
