The Garden of Eden is included in display (8)
I believe the answer is:
paradise
'the garden of eden' is the definition.
(thesaurus)
'is included in display' is the wordplay.
'included in' indicates putting letters inside.
'display' becomes 'parade' (parade is a kind of display).
'is' inserted within 'parade' is 'PARADISE'.
(Other definitions for paradise that I've seen before include "Heaven; Eden" , "Happiness" , "heavenly destination" , "Idyllic place" , "Utopia" .)
