Claim 7:
8. A manufacturing method of a display device, comprising:
providing a substrate, and forming a conductive layer comprising a plurality of sub-conductive layers stacked in sequence on the substrate;
forming a reflective layer on the conductive layer, and forming a plurality of cylindrical holes in the reflective layer; and
forming holes with arc-shaped bottom portions in the conductive layer, and connecting each of the holes with the arc-shaped bottom portions to one of the cylindrical holes to form a flask-shaped hole, wherein the flask-shaped hole comprises an arc-shaped bottom portion of the arc-shaped bottom portions and a cylindrical portion that is formed of one of the cylindrical holes and connected to the arc-shaped bottom portion, the cylindrical portion penetrates the reflective layer, and a depth of the arc-shaped bottom portion is greater than half of a thickness of an uppermost one of the sub-conductive layers and less than a thickness of the conductive layer.
