"The DFB is charged with the setting-off of fireworks and the improper conduct of supporters (display of inappropriate banners and symbols, and inappropriate chanting)," European soccer's governing body said in a statement on Tuesday.
The Football Against Racism in Europe (FARE) group said a neo-nazi banner was displayed by German fans.
FARE, an independent anti-discrimination network working closely with UEFA to identify instances of racism at matches in the tournament, tweeted on Tuesday: "FARE can confirm that one of our observers reported a neo-nazi banner in the German section at match versus Denmark game in Lviv on Sunday".
The DFB has already been fined 10,000 euros (around £8,000) at this tournament by UEFA after Germany fans threw what appeared to be rolled up pieces of paper at Portugal players during their match in Lviv on June 9.
