To solve a problem in display of a graph of a moisture uneven state of a whole of a grain layer in a small display screen of a control panel of a grain drier wherein it is hard to see the display when moisture differences per grain layer are small.

The display screen for the grain drier is provided with a storage chamber (10) storing grain, a moisture meter (9) measuring respective representative moisture values (m) of plural portions per set interval from a whole of the storage chamber (10), and the display screen (30) displaying the representative moisture values (m) in a two-dimensional graph. An ordinate of the graph indicates a scale of the grain moisture values, and an abscissa of the graph indicates the measuring portions. An average moisture value (n) of the representative moisture values (m) is displayed as a center value of the scale of the ordinate. A numerical value near the highest representative moisture value and a numerical value near the lowest representative moisture value of the representative moisture values (m) of the measuring portions are respectively displayed as an upper limit value and a lower limit value of the scale of the ordinate.
