Display name
This is the information used as a breadcrumb trail and in the left navigation. When adding the Display Name, consider how the name will affect the breadcrumb trail and navigation performance. A very long display name will cause text to wrap to multiple lines in the left navigation.
Title
This is the name that appears as the headline in your page and at the top of the Web browser window when viewing the published page.
