Display list == Retained mode?

I was reading the Red Book and saw that in chapter 7 the autor makes some comparisons between display lists and immediat mode, so, display lists are know as Retained mode too, or I am living with Alicia in wonderland?

Not really… “retained mode” is usually applied to scenegraph APIs which manage the transform and traversal stuff, usually including some sort of dynamic optimization (grouping primitives by texture etc). Display lists are just static batches of immediate-mode commands. You can use them to help implement a retained-mode layer, but it’s not really the same thing.
