Your last statement can presuppose a question such as "Are there any shoes in the display?" "No, there are no shoes in the display"

If someone had said "Is there a banana in the fridge?" You'd respond "There is no banana in the fridge"

You're referring to an absence or a zero number, but using the singular form.

However when you specifically number something 'zero' it isn't so much that it "is plural" as "is not singular" Since it is not singular, you don't use the singular, which leaves you the plural.
