"Minority Report" is the first thing, that comes to my mind. But, of course, there are so many other SF examples... as well as many CSI-like-absolutely-no-SF-movies etc.

Why? What is the reason for telling people, that using screens, viewports etc. with transparent background and all the things seeing behind is useful, when it isn't useful at all. It makes your eyes tired and it makes you less focused to details, disoriented etc.

Is there any SF book or movie, that in particular addresses this topic -- i.e. contains reasonable explanation, why such screens are used or an attempt to prove, that they're better than nowadays non-transparent screens?

    In addition to the Rule of Cool, it's probably easier to do camera angles if your actors can be seen through their screens. – MrTheWalrus Jun 24 '15 at 13:50

    The question says "SF works" but I doubt you find this in SF books/stories much if at all. Only in movies, because it looks cool. – GEdgar Jun 24 '15 at 14:20

    @GEdgar yeah I can't really imagine any author over the age of twelve adding something like and you could totally see straight through the lcd screen, like it was clear glass, but it's not. Trust me, it looks sweet – Daft Jun 24 '15 at 15:47

To answer the question in-universe, no, there is no reason to have clear, see-through screens.

Out-of-universe, as noted in some of the comments, it's so that viewers can see the characters better. Here's a TVTropes article about it: In Space Everyone Can See Your Face WARNING: TVTropes link

Basically, the production company is paying these actors a lot of money, and they want to make sure they are getting their money's worth.

    You explain nicely, why it is used in movies. Is that mean, that answer to my question is "No. There are no known SF works with proper explanation of using such thing"? – trejder Jun 25 '15 at 7:37
