• a plurality of inner bottom portions;
• a plurality of wall portions surrounding each of the inner bottom portions, the wall portions including a plurality of inner wall portions located on an inner side in a plan view, and a plurality of outer wall portions located on an outer side in the plan view, with the inner wall portions having the same height and the outer wall portions having smaller heights than the inner wall portions as measured from the inner bottom portions;
• and
• a plurality of outer bottom portions arranged on an outer side of the outer wall portions in the plan view, the outer bottom portions being positioned higher than the inner bottom portions.

A light-reflecting member comprising:

• a plurality of first regions each surrounded by a plurality of first wall portions in a plan view with the first regions being arranged in a matrix in the plan view;
• a plurality of second regions arranged on an outer side relative to the first regions in the plan view, each of the second regions including
• an outer wall portion at least partially inclined so that a height of the outer wall portion is reduced from the outer side toward an inner side, and
• a second wall portion connected to an inner side end of the outer wall portion;
• a plurality of third regions arranged between the first regions and the second regions in the plan view, each of the third regions includes at least one third wall portion having a height smaller than a height of each of the first wall portions.
