Displeasure is a feeling of annoyance and disapproval. Anger, expressed with restraint.
The word is formal and it implies rank, since displeasure is usually felt by somebody with the standing to express it, which is why royal displeasure is a phrase and nobody records their neighbour's. It appears in expressing displeasure and incurring somebody's displeasure. What distinguishes it from anger is the control, since displeasure is shown rather than lost. The verb displease and the adjective displeased belong with it.
