If there is a rear bridge, the angle of its windows would be strange. The wall is canted in the wrong manner, see the orange lines, compared with the right manner (blue line) of the front bridge.
I know some ships do the same, but in those cases as I know the ship (actually boat) is very small so the window follows the angle of the deck house. I don't see that kind of constraint in a CV to do the same, nor is there a reason to do differently than the front bridge.
Any guess?

Forward bridge widows are angled to get a few more degrees of look down view, better suited for scanning things down there on the deck. Reversed that angle to rare widows for better look up view, as they would be scanning things up in the sky approaching the general vicinity of the ship.
