Sandwiched between glass, or plexi?
I have an 8x10 piece of lith film taped to one of my windows with a piece of white paper behind it. It's actually an enlargement from a medium format negative. It's film, anyway. It's been there for 5 years and nothing has happened to it.
I don't know why anyone would be interested in displaying a negative.
Large format paper Calotype negatives from 19th C. salt prints are often displayed as works of art in themselves. Sometimes they are paired with the positive print as well. They can be very beautiful displayed this way.

Microphotography has been around since 1839 and many microphotographs from that era still exist today in excellent condition. That process involves sandwiching a photo between a glass microscope slide and a glass cover slip. They often used Canada Balsam to make permanent mounts back then. I have a few of these and have made a few myself using modern film cut down to fit on a microscope slide. I suppose you could do this process on a larger scale between any size glass plates but I would practice on negatives you don't care about.

A while back I broke the glass when I was framing one of my prints and trooped on over to the glass shop and asked them how much a 16x20 sheet of glass would run, and they told me some exhobitant amount, so I declined and drove over to Michaels and bought a 16x20 frame that was on sale, and kept the glass and threw the frame way, and saved a ton of money. So now I go to Michaels for all my glass needs.That would be a good idea. I do have a glass store round the corner!

Thrift stores are even better for it. You can get huge frames for under $10.
For black and white, the emulsion should be resistant to degradation, but the substrate may be vulnerable.So im thinking, if thats the case, then modern film or lith film would be able to somewhat stand to the test of time being displayed

And discoloration might also occur.
Perhaps look into long term display issues for X-rays.
