ABSTRACT:
The present invention provides a display apparatus in which there is no shorting between the electrodes and cathode, and there is little variation in the amount of emitted light within a single luminescent layer. A display apparatus is employed in which first and second bank layers are extended to the peripheral edge section of electrodes, the first bank layer is extended farther towards the center of electrodes than the second bank layer, a first laminated section is formed on the first bank layer, an opening is provided in the bank sections, functional layers are composed of a positive hole injection/transport layer and a luminescent layer, and the positive hole injection/transport layer is composed of a flat section formed on the electrodes and a peripheral edge section formed on the first laminated section of the first bank layer.
