How is "truth" defined in philosophy?

Does "truth" only concern validity? If a proposition does not violate the fundamental laws of logic, such as the law of identity;A=A, the law of non-contradiction, excluded middle, is it deemed "true"? Even if a logical deduction of premises is valid, what if the premises do not hold any soundness? And hence, give rise to a logically valid conclusion but an unsound one given that the conclusion is derived from unsound premises?
