'this' is the definition.
The definition suggests a singular noun which matches the answer.

'extremely good one with halo displays' is the wordplay.
'extremely' means to remove the middle letters (only the extremes of the word are used).
'with' is a charade indicator (letters next to each other).
'displays' indicates an anagram (I've seen 'displaying' mean this (the anagrammed letters display the answer)).
'good' with its centre taken out is 'gd'.
'gd'+'one'='gdone'
'gdone' put after 'halo' is 'halogdone'.
'halogdone' anagrammed gives 'ANGELHOOD'.
