A method for producing a luminescent organic film, the method including: coating a solution containing a π-electron conjugated compound precursor A-(B)m and at least one kind of a luminescent dye, where the π-electron conjugated compound precursor A-(B)m contains a leaving substituent; and applying external stimulus to the π-electron conjugated compound precursor A-(B)m to eliminate the leaving substituent thereof, so that the π-electron conjugated compound precursor A-(B)m is converted to a π-electron conjugated compound A-(C)m and an eliminated compound X—Y as in the following reaction formula (I):
