Displayed on a wall (4)
I believe the answer is:
hung
'displayed on a wall' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for hung that I've seen before include "Suspended" , "(Of parliament) with no overall majority" , "Dangled" , "(Of a jury) unable to agree on a verdict" , "(Of a painting) exhibited (in a gallery)" .)
