ABSTRACT:
The present invention provides an organic EL display device which has a long lifetime. The organic EL display device includes a plurality of pixels each of which is constituted of a top-emission-type active matrix organic EL element. The EL element includes: a pixel electrode; a reflective layer arranged between the pixel electrode and an active element and is formed over a leveling layer; an organic light emission layer; and a common electrode. The reflective layer includes: a first reflective layer which is made of high-melting-point metal; and a second reflective layer which is arranged on the first reflective layer. The second reflective layer includes a planar pattern in which an outer periphery of the second reflective layer is surrounded by the first reflective layer. The pixel electrode extends outward from the first reflective layer and the second reflective layer.
