Arranged quite a display (5)
I believe the answer is:
array
'a display' is the definition.
('array' can be a synonym of 'display')
'arranged quite' is the wordplay.
'arranged' becomes 'arr' (abbreviation).
'quite' becomes 'ay' (both can mean 'yes').
'arr'+'ay'='ARRAY'
(Other definitions for array that I've seen before include "Order - arrangement" , "Matrix; elaborate clothing" , "Imposing show or military order" , "Lay out, arrange" , "Impressive exhibition" .)
