Abstract: In an organic EL display device configured in which an acrylic resin layer is disposed under a barrier layer that protects an OLED for flattening the barrier layer, floating the barrier layer caused by penetration of moisture into the acrylic resin can be prevented. A side surface of a bank formed in a boundary of pixels is formed into a cliff part having an inclination angle of 90° or larger in most portions of a circumstance of each pixel part, and formed into a gently sloped part having the inclination angle smaller than 90° in a part of the circumference. The electrode parts disposed within the respective pixels are connected to each other through an electrode part disposed on an upper surface of the bank, and electrode parts disposed on the gently sloped parts to form an OLED common electrode.
