Abstract

A display apparatus includes a solid state light-emitting element which is mounted on a base in an orientation so that light can be transmitted to a viewer from opposite major sides of the solid state light emitting element. To enable light to be transmitted to a viewer from opposite major sides of the solid state light-emitting element, the solid state light-emitting element is mounted in an on-edge orientation. To mount the solid state light emitting element in an on-edge orientation, support pins engage opposite minor side or edge surfaces of the solid state light emitting element and support it with the major side surfaces of the solid state light emitting element exposed and extending perpendicular to the mounting surface on the base.
