Stop using display of work (4)
I believe the answer is:
opus
'work' is the definition.
(an opus is an artistic work)
'stop using display' is the wordplay.
'display' indicates the answer is hidden within the clue (I've seen 'displaying' mean this).
'OPUS' is hidden within 'stop using'.
'of' is the link.
(Other definitions for opus that I've seen before include "Creative work, eg in writing, art or music" , "Work (mus.)" , "Musical composition in the soup" , "Artistic work" , "Composer's work" .)
