An in-vivo information display device includes a communication unit that communicates with a receiving device that receives in-vivo information transmitted, at a predetermined time interval, from a body-insertable device that is introduced into a subject and acquires the in-vivo information regarding an inside of the subject a transmission requesting unit that transmits a transmission request for the in-vivo information to the receiving device via the communication unit and a display unit that displays the in-vivo information received via the communication unit from the receiving device in response to the transmission request. The transmission requesting unit transmits the transmission request to the receiving device at a first time interval smaller than the predetermined time interval, and the transmission requesting unit transmits the transmission request to the receiving device at a second time interval larger than the first time interval when one or more the in-vivo information is received.
