When we give inputs to SR flip-flop, the outputs we get should be a compliment. That's is Q and Q' When S and R are high (S=R= 1),

The o/p is Q=0 and Q'=0. That's why it's called invalid state.

When both inputs of SR flip flops are high i.e. S = 1 and R = 1, the state in which FF goes is called as an invalid state.
