    Abstract: The purpose of the present invention is to precisely determine an area of the evaporated organic EL material in an organic EL display device, where organic EL layers in individual pixels emit light of different wave lengths. The purpose is realized by a structure that: A display device comprising: pixel electrodes are formed in a matrix arrangement on a substrate and a space exists between the pixel electrodes, a bank, which covers an edge of the pixel electrode, having an opening that exposes a part of one of the pixel electrodes, a first projection formed on a top of the bank and along a side of the opening, a second projection formed in an area that is near to the center of the top of the bank than the first projection is, in a plan view.
