Thanks in anticipation
There are two main causes of Leylandii browning
(1) cutting it back too hard
(2) an aphid that specialises in ruining Leylandii, not very common but found here and there.
Given you have just cut it back, (1) seems most likely.
Whichever the cause, it never grows back green again in the area that it is brown. If you have just a small patch, you can often bend other branches over the brown area. If it is a big area, you are stuffed.

This is one of the several reasons why leylandii is to be avoided. There are other more compliant conifers available, if you must have conifer. Otherwise things like several kinds of berberis and cherry laurel make a much easier to manage and pleasant evergreen hedge.
