摘要： A deposition mask includes: a first mask having an opening formed therein; and a second mask superposed on the first mask and having a plurality of through-holes formed therein, the through-hole having a planar dimension smaller than a planar dimension of the opening; wherein: the deposition mask has a plurality of joints that join the second mask and the first mask to each other; the plurality of joints are arranged along an outer edge of the second mask; and a notch is formed at a position in the outer edge of the second mask, the position corresponding to a space between the adjacent two joints.

摘要： A deposition mask includes an effective part in which a plurality of openings are provided, and an outer frame part surrounding the effective part. The effective part includes an outer peripheral area that is adjacent to the outer frame part, and a central area which is surrounded by the outer peripheral area and has a thickness larger than a thickness of the outer peripheral area.

摘要： An LED leadframe or LED substrate includes a main body portion having a mounting surface for mounting an LED element thereover. A reflection metal layer serving as a reflection layer for reflecting light from the LED element is disposed over the mounting surface of the main body portion. The reflection metal layer comprises an alloy of platinum and silver or an alloy of gold and silver. The reflection metal layer efficiently reflects light emitted from the LED element and suppresses corrosion due to the presence of a gas, thereby capable of maintaining reflection characteristics of light from the LED element.
