This is usually your legal name and is filled in while setting up your account. The display name is what appears primarily on your account. Your Skype display name is what users see when they look you up on the app while your Skype name can be used to easily locate your account. However, your Skype name is not the same as your ‘ display name‘. These are all just synonyms for the same thing.
