How to make field label as node reference link?
I propose to do so (if you have a module Display Suite): 

Go to ../admin/structure/ds/view_modes

Add a view mode: name is "label" and entities: "Node" 

Then go to ../admin/structure/types/manage/your-content-type/display and on "Custom display settings" tab check the "Label" mode

Now go to ../admin/structure/types/manage/your-content-type/display/label select "Reset" (ds_reset) Layout, then make visible only the "Read more" and customise it: "Link text" - "See details" for example... 

Then on referenced content type select "Rendered entity", and "View mode" - "Label" 

Done!
