Abstract
In an interlayer insulating layer, upper surface portions in edge regions near banks are located higher than an upper surface portion in a central region. In an anode formed to extend along upper surface portions, upper surface portions in edge regions near banks are located higher than an upper surface portion in a central region. In hole injection transporting layer formed to extend along upper surface portions, upper surface portions in edge regions near banks are located higher than an upper surface portion in central region. In an organic light-emitting layer, upper surface portions in edge regions (regions Cand C) near banks are located higher than an upper surface portion in a central region (region C). As a result, in an organic light-emitting layer, thicknesses Dand Dare equal to thickness D.
