name member
https://w3c.github.io/manifest/#name-member

The manifest's name member is a string that represents the name of the web application as it is usually displayed to the user (e.g., amongst a list of other applications, or as a label for an icon).

The name member serves as the accessible name of an installed web application.

The "accessible name" and the display name (or its short_name equivalent) really should be localized to match the expectation of the user. Many apps are localized into many languages, but the design of manifest (with lang and dir as top level items applying to all values inside the manifest and an on-going discussion about localization) suggests that this is not yet fully baked.
