The 取向層 124B may be absent at the concaves CV7. The 取向層 124B may have a thickness TP5B at the protrusions PP7 to define the second portion PP7B of the protrusion PP7 and a thickness TU5 at the portion in contact with the 取向層 126A. In some embodiments, the thickness TP5B may be substantially the same as the thickness TU5. In some embodiments, the concaves CV7 may penetrate through the 底層 124B and extend in the support plate 122B.
