When you are displeased, you are annoyed or not satisfied — you wanted something better, and it shows. It is a quieter, more polite word than angry. A parent, a teacher, or a boss may look displeased: they have not shouted, but the face, the silence, or the short reply says they are not happy with you or with the result. You can be displeased with a person, with a piece of work, or with the way something was done. It sounds a little formal, even a bit old-fashioned; younger people in everyday talk more often say annoyed, not happy, or not pleased — though actually those are the same feeling in plainer clothes. Displeased still fits when you want to sound measured, not furious. A displeased person may stay polite; they are simply not pleased.
