What does "V.A." mean in datasheet dimensions?

This is not a standard dimensioning abbreviation according to any standard I'm familiar with.

Instead, I suggest the (in 20:20 hindsight, obvious) meaning that the dimensions given refer to the nominal size of the LCD Viewing Area.

After looking into the linked LCD datasheet and answers here, I looked into other display products of the same company NEWHEAVENDISPLAY. And the interesting thing I found is apart from V.A. they use another therm called as A.A. Below is an example. Adding the datasheet link as well, if someone more interested can look into.

V.A. can be Viewing Area or Viewing Angle(if mentioned in degrees)

A.A. is Active Area also called as effective area which the area for active pixels or icons or segments or patterns.

These links say all the same link1, link2 and link3.

Just hope ambiguity stops here.
