You can extract the contact list from your subquery by treating it as the List<Contact> that it is. If the List has data, grab it and assign it to the contact display list.

Contact[] displayContacts {get;set;} //display in the vf page using a repeat

Account[] accts =[SELECT Name, AccountNumber ,Type , Industry , Rating,(SELECT Name , MobilePhone,Title from Contacts) 
                 FROM account
                 WHERE ID = :recId ];

Account acct = accts[0];
//acct.Contacts is a List<Contact>
if (!acct.Contacts.isEmpty()){
    displayContacts = acct.Contacts;
}
