To specify a farm field sensor displayed on a portable terminal, and simply confirm farm field information.SOLUTION: A farm field information display system includes: a farm field sensor which acquires positional information of an installed position and information of an installed farm field, and transmits the positional information and the farm field information； a data center which receives the positional information and the farm field information from the farm field sensor, stores individual information of each farm field sensor while linking to the positional information and the farm field information, and is constituted so as to be capable of transmitting the individual information, the positional information and the farm field information of the linked farm field sensor； a portable terminal which acquires positional information of the present position and orientation information of a terminal, transmits the positional information, and receives the individual information, the positional information and the farm field information of the farm field sensor which are transmitted from the data center, in which a farm field sensor included in an image captured by an imaging device built in the portable terminal is specified on the basis of the positional information of the farm field sensor and the positional information of the portable terminal, and the orientation information, and farm field information acquired by the specified farm field sensor is displayed on a display device.SELECTED DRAWING: Figure 7
