Abstract: According to one embodiment, a deposition method includes preparing a processing substrate in which a lower electrode, a rib, and a partition including a lower portion and an upper portion arranged on the lower portion and protruding from a side surface of the lower portion are formed above a substrate, setting a spread angle of vapor of a first material emitted from a first deposition head to a first angle, and depositing the first material on the processing substrate, and setting a spread angle of vapor of a second material emitted from a second deposition head to a second angle larger than the first angle, and depositing the second material on the processing substrate on which the first material is deposited.

Abstract: An organic EL display device includes in order from a substrate side: a metal layer; an insulating layer formed on the metal layer; a first electrode layer formed on the insulating layer; an organic layer formed on the first electrode layer; and a second electrode layer formed on the organic layer. The metal layer is for use as a reflective layer configured to reflect, on a surface of the metal layer, light generated from the organic layer by applying a voltage between the first electrode layer and the second electrode layer.
