A mental and physical state display device allows a user to intuitively grasp his/her mental and physical state substantially in agreement with his/her individual perception. The display device includes a display unit; and a display-processing unit that displays, on the display unit, state-indicating graphics in chronological order in a monthly, weekly or daily calendar format, with the state-indicating graphics indicating a mental and physical state computed based on a result of measurement of biometric information of a user, and representing levels of the mental and physical state in a distinguishable manner by a change in the respective state-indicating graphic. The display-processing unit displays at least one of the state-indicating graphics that corresponds to a criterion of the mental and physical state as a criterial state-indicating graphic that is distinguishable from a remainder of the state-indicating graphics, with the criterion being set on a user-to-user basis.
