 * `display`: OPTIONAL. Array of objects, where each object contains display properties of a Credential Issuer for a certain language. Below is a non-exhaustive list of valid parameters that MAY be included:
   * `name`: OPTIONAL. String value of a display name for the Credential Issuer.
   * `locale`: OPTIONAL. String value that identifies the language of this object represented as a language tag taken from values defined in BCP47 [@!RFC5646]. There MUST be only one object for each language identifier.
+  * `logo`: OPTIONAL. A JSON object with information about the logo of the Credential Issuer with a following non-exhaustive list of parameters that MAY be included:
+    * `uri`: OPTIONAL. String value that contains a URI where the Wallet can obtain a logo of the Credential from the Credential Issuer. Wallet needs to determine the scheme, since the URI value could use `https:` scheme, `data:` scheme, etc.
+    * `alt_text`: OPTIONAL. String value of an alternative text of a logo image.
 * `credential_configurations_supported`: REQUIRED. Object that describes specifics of the Credential that the Credential Issuer supports issuance of. This object contains a list of name/value pairs, where each name is a unique identifier of the supported Credential being described. This identifier is used in the Credential Offer as defined in (#credential_offer_parameters) to communicate to the Wallet which Credential is being offered. The value is an object that contains metadata about specific Credential and contains the following parameters defined by this specification:
   * `format`: REQUIRED. A JSON string identifying the format of this Credential, i.e., `jwt_vc_json` or `ldp_vc`. Depending on the format value, the object contains further elements defining the type and (optionally) particular claims the Credential MAY contain and information about how to display the Credential. (#format_profiles) defines Credential Format Profiles introduced by this specification.
   * `scope`: OPTIONAL. A JSON string identifying the scope value that this Credential Issuer supports for this particular Credential. The value can be the same accross multiple `credential_configurations_supported` objects. The Authorization Server MUST be able to uniquely identify the Credential Issuer based on the scope value. The Wallet can use this value in the Authorization Request as defined in (#credential-request-using-type-specific-scope). Scope values in this Credential Issuer metadata MAY duplicate those in the `scopes_supported` parameter of the Authorization Server.
