The second light blocking portion includes a base portion, a barrier wall protruding from the base portion and a protruding portion protruding from the barrier wall. A total height of the second light blocking portion at the base portion thereof is less than a total height of the second light blocking portion at the barrier wall and the protruding portion thereof.
