I remember the term "display closure" from Scheme compilers / compilation techniques.

"While researching
how other systems had coped with similar problems, I ran across
a book on the implementation of Algol 60 by Brian Randell and
Lawford Russell [46], which described the use of displays for
speeding access to the free variables of a local function. A display is
a bank of memory locations or registers, each pointing to one of the
frames whose variables make up the current lexical environment.
Displays weren't directly usable for my purposes, but I was able
to make several adjustments and from the display model derived
the notion of a display closure, a heap-allocated vector-like object
holding a code pointer and the values of the free variables [16]."
