Abstract
An organic EL device that increases light emission efficiency by promoting the uniformity of light-emitting layer thickness while reducing the interval between pixel regions, and a display provided with the organic EL device. An organic EL device () has two or more first banks () extending in a line state, a plurality of second banks () that define pixel regions () by dividing a region between the adjacent first banks () and have a height lower than that of the first bank (), a hole transport layer () provided independently for each pixel region (), and an insulating inorganic film () provided on edges of the pixel region () along side faces of the two first banks () facing each other and defining the pixel regions (). With the configuration, even if the interval between the pixel regions is small, a layer in contact with an upper face of the insulating inorganic film () is formed flat by the insulating inorganic film () and a layer thickness of the layer is made uniform.
