Is it harmful to list too specific research interest in personal statement? I'm undergraduate who are applying US research program. I have one interest field in which I have read 1 survey and 3 other papers (I know it is not enough). I only have some vague and primitive idea so that I am not sure I will do research in the field in graduate program. 

I'm afraid if I write my research interest too specific and there are no professor who has knowledge about or is interested in such field, the admission committee would think my goals do not coincide with their department research interests.

Is it a disadvantage to write research interests too specific?

It is also possible that what I believe is too specific may be not specific enough for some professor.
I am not sure if a statement would be harmful, it will be a question of how well you appear to know the field. You are right in that you have not nearly read enough. It would be better to simply state that you are interested in such and such a field without going into depth, after all being interested is hardly a problem. If you try to get into arguing for why a field is interesting without having a good grasp of the field, you run into the likely situation that instead of primarily showing your interest, you simply expose your lack of knowledge. No-one would expect an undergraduate to have deeper knowledge about a specific research topic but if you try to argue for some field based on very sketchy knowledge, you may come across as naive. I therefore think it is better to simply state fields that you are interested in without going into specifics. If you manage to read up on a field (which would take, likely significant, time) so that you have a perspective, then such a statement would be a definite positive. Coming across as having good general skill (knowledge and abilities) is still the most important aspect.
