Ostentation is the making of success, wealth, power, etc, visible. Wearing an expensive watch or suit, driving an expensive car, prominent display of trophies or certificates, etc. Informing people in speech or writing of one's high opinion of one's own abilities is commonly called boasting. In many cultures, the perception of boastfulness cannot be cancelled by the speaker's use of a form of words such as "no boasting intended here". Boastfulness, in short, is in the ear of the hearer. There is a modern conversational tactic called 'humblebragging' where boasting or bragging is disguised by humble phrasing.
