Looks like the normals are facing the wrong way. Select the faces in Blender and hit CTRL+N to recalculate normals or CTRL+F and select "Flip Normals".

In Blender the properties panel ( shortcut N) has $$anonymous$$esh Display options for normals that can visualize the normal direction with some lines. Also in the properties panel under Shading you can enable "backface culling". Then the view should display the same as if you imported the mesh with normals into Unity.
