Use COUNT or MAX functions inside of a query, and you have no data found

Question

I'm writing a query with a COUNT and a MAX function.
    SELECT  li.id
             , MAX(m.display_date)
            , COUNT(*)
     FROM li JOIN m  ON (m.LIID=li.LIID)
    WHERE m.DISPLAY_DATE < SYSDATE - 7
    GROUP BY  li.id;I would like to write a query that returns always a row foe each row in the table li.
If there are no records with the condition "WHERE m.DISPLAY_DATE < SYSDATE - 7", I would like to have a row with
- COUNT(*) = 0
- MAX(m.display_date) = TO_DATE('2010-06-08', 'YYYY-MM-DD'
