A cap with a display device includes a display element suspended in a position below a visor of the cap and in front of the forehead of a wearer and above the eyes of the wearer so as to allow a display surface of the display element to be directed ahead of the wearer, and a concave mirror suspended in a position below the visor and ahead of the display element from the wearer so as to allow a reflective surface of the concave mirror to be directed to the eyes of the wearer. The cap with a display device enables the wearer to observe an enlarged virtual image derived from an image displayed on the display element.
