Not really. Transparencies subtract some colours from the transmitted
light; prints subtract some from the reflected light. Displays make
their own...


Ah, so that is why they are backlit then?

So they can 'make their own?
What a prat. An LCD display IS a color transparency.


No it is not!

A transparency is a subtractive process.
An lcd is additive.

Each pixel in a film transparency has three filter layers each of which can
absorb a colour.

Each pixel on an lcd is made from three different colour subpixels.
The subpixels each have a colour filter behind them to make them RGorB.
