Default selecting date and previous dates

I have a database with an event date. I need to select the latest date and the varying amount dates previous to this. I came up with this but was
wondering if there would be a more efficient way to do this.

SELECT display_date FROM myDB WHERE display_date
BETWEEN SUBDATE((SELECT MAX(display_date) FROM myDB), INTERVAL 10 DAY)
AND (SELECT MAX(display_date) FROM myDB)
ORDER BY display_date

Example: Data in database
2004-05-27 00:00:00
2004-05-25 00:00:00
2004-05-26 00:00:00
