The article storage facility as defined in claim 1, wherein the display displays, as a kind of the gas supply state, purge progress which represents a proportion of the amount of the inactive gas that has been supplied to the container with respect to an internal volume of the container. 3. The article storage facility as defined in claim 2, wherein when the container is carried into the storage section by the transport portion, the display displays the purge progress for the container. 4. The article storage facility as defined in claim 1, wherein the supply pattern includes a plurality of supply phases that are defined such that a combination of a supplying timing of the inactive gas and a target flow rate is different for a different supply phase, andwherein the display indicates, as a kind of the supply state, which one of the supply phases the container is subjected to at the time by means of different colors depending on the supply phase. 5. The article storage facility as defined in claim 4, wherein the gas supplying portion is configured to be able to supply the inactive gas to clean a gas supply nozzle which fits into a gas supply opening provided to the container, in a predetermined period before the container is carried into the storage section by the transport portion, andwherein the display indicates, as a kind of the supply state, the fact that the inactive gas is being supplied to clean the gas supply nozzle by means of a color that is different from the colors representing respective ones of the plurality of supply phases. 6. The article storage facility as defined in claim 1, further comprising: a load presence period acquiring portion which acquires a load presence period which is an elapsed time after the container is carried into the storage section,wherein, if the load presence period for a given container exceeds a standard load presence period defined in advance, the display further displays warning information indicating that the standard load presence period has been exceeded, in the display section corresponding to the storage section in which the container is stored. 7. The article storage facility as defined in claim 1, further comprising: an identifying information acquiring portion which acquires identifying information of the containers stored in the storage sections,wherein, if the identifying information acquiring portion is unable to acquire identifying information for a given container, the display further displays warning information indicating that the identifying information is not acquired, in the display section corresponding to the storage section in which the container is stored. 8.
