Hi Bob,
Yes, I've found no shortage of statements on the web saying they
Were LCD or Plasma, just haven't found anything definitive.
`
The early plasma displays, like the Compaq III portable, Grid Case
And others were definitely orange-red. For a while it was thought that
Plasma displays were going to take over the world, which they did for
a while. There was apparently a lot of work going on in color plasma
displays in the 80's, but it seems unlikely that a suitable color plasma was
available and rated for aircraft service by 1985. I found a NASA tech report
concerning developing plasma displays for the Space Shuttle.
The commercial color displays arrived in 1992, but they were developed
with much higher res and color gamut than the Concorde use would have
required.
Given the time period, I wonder if there is anyone at modern
Day Marilake that would still have the information. They did bid the proposed
Updated Mach display for the return to flight planned upgrade, but that
Never really happened. Called the "Rocket Project". There is a reference
On an old (2005) edition of their web page. It does say that that version was LCD.
You can see that here:

Select "Products" then "Concorde Displays"

This link mentions the Marilake displays were LCD:

Most plasma displays I've seen were more red or red/orange. The Marilake displays look
too yellow. Could be a monochrome LCD with an EL backlight.

Actually, it is a "Marilake" display, built
by Marilake in the UK, still in business.
From what I have been able to find, they were installed in British
Airways Concordes Around 1985, to replace a much less attractive 7
segment LED display. The French Concordes apparently retained the earlier LED type
display.
The other article is referring to a different display that replaced the Marilakes.
Most of the references I have found indicate the Marilakes were Plasma displays.
Nothing definitive, however.

Just found this article, and apparently the old
displays were
replaced with the new ones shortly after the grounding in 2000/2001.
This would mean they are probably LCDs.

Also, here's a photo that very clearly shows the refresh:

Interesting. Searching for 'Marrilite display' (I wonder what that is)
turned up this page, which mentions "There was a plasma display at the front of the
cabin showing the altitude, the air temperature and the current speed in both miles per
hour and Mach number."
