How to show Civicrm Event in fullcalendar?
There was an Extension built that says it integrates with Drupal FullCalendar
https://civicrm.org/extensions/event-calendar-extension
but it doesn't show a release version for civi since 4.4

Otherwise if you are wanting to do this directly with Drupal Views have you tried enabling the CiviCRM Entity module to see if that can help you?

And there is now a sample View that works with 4.6 with civicrm_entity enabled here
