Thanks. Daijisen did not get that technical, but you're right that the results consistently show an isometric view, which a 3/4 view might not be.

also in this link above, it says "本来の英語の意味からはかけ離れている"

I have some doubts on the "three-quarter view" definition - the reason being that searching through google image "クォータービュー" gives widely different results than what you get with "three-quarter view" or "three-quarter view games". 
The definition for "isometric view" is: "It is an axonometric projection in which the three coordinate axes appear equally foreshortened and the angle between any two of them is 120 degrees. " and this is easily noticeable in the first link above, also these are the results for an image search for "クォータービュー"
On the other hand, "three-quarter view" is used in the context of art/painting in which it means an in-between of front and side view, and in the context of videogames with a search for "three-quarter view games" brings up results such as "legend of zelda: a link to the past" (second link above) and "final fantasy 6" (third link above), which like for the meaning of three-quarter in art, show only 2 sides of things (in this case front and top) instead of the three sides like the isometric view does.
In short, googling "クォータービュー" doesn't bring up "three-quarter view" results so I think that's not accurate

this can easily be seen with a google image search, this link above also confirms it
