From 1993, this is the LaserDisc created to show off Mitsubishi's new 40-inch CRT TVs. Mitsubishi had first broken the size barrier with 30 and 35-inch CRT's in the 80s, and the 40-inch was their crowning achievement. They made projection TVs too, but CRTs still had the best quality picture. The disc talks about Mitsubishi's previous accomplishments in the world of TV too, notably big-screen.

As far as my research can tell me, RCA technically made the first big-screen rear-projection TV in 1947. It did not end up selling too well due to the image being too dim to be comfortable to view.
