"Well-bred" in its full sense means more than just well-mannered. It implies a formation through upbringing, education, and social environment that has produced not just polite behaviour but a certain ease, confidence, and cultural fluency. In older and more formal usage it also carries clear class implications — well-bred people come from backgrounds where the right values and behaviours were transmitted as a matter of course. Modern usage has softened this, but the social weight persists.
"Ill-bred" is specifically about the failure of upbringing to produce good manners, social awareness, and consideration for others. It is not primarily about formal education (someone can be highly educated and ill-bred; someone can have little formal schooling and be well-bred). It judges the product of the rearing environment, not the product of the school.
A trick to remember it
well-bred = "well brought up", the participle of "breed" (to raise/rear). Think of a "well-bred" dog and apply the same logic to a well brought-up person.
