Notice to cut out and show (6)
I believe the answer is:
parade
'show' is the definition.
(I know that parade is a type of display)
'notice to cut out' is the wordplay.
'notice' becomes 'ad' (both can mean an advertisement).
'to cut' becomes 'pare' (paring is a kind of cutting).
'out' means one lot of letters goes inside another.
'ad' placed within 'pare' is 'PARADE'.
'and' acts as a link.
(Other definitions for parade that I've seen before include "'Procession of bands, floats, etc (6)'" , "Public procession or ceremonial march" , "Cavalcade or procession" , "Flaunt; ceremonial march" , "March past" .)
