DISPLAY DEVICE AND DISPLAY CONTROL METHOD

A display device (100) includes a receiving section (12), a registering section (2112), a display section (11), an identifying section (2111), and a changing section (212). The receiving section (12) receives selection of a label from a user. The registering section (2112) registers the label and a format set in association with each other. The format set includes format items to be embodied in a character display format and format contents each indicating a content of a corresponding one of the format items. The display section (11) displays a character string including a first character. The identifying section (211) identifies the first character. The changing section (212) changes the character display format of the first character based on the format set associated with the label.
