Problems solved by technology

Since the amount of light emitted from the light emitting layer 910b is proportional to the number of injected holes, there is a problem that a portion with a large amount of light emitted and a portion with a small amount of light emitted are generated in one light emitting layer.

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.

Description

technical field [0001] The present invention relates to a display device and a manufacturing method of an electronic instrument and the display device. Background technique [0002] In recent years, light-emitting materials such as organic fluorescent materials have been made into inks, and according to the inkjet method of ejecting the ink (composition) on the base material, a method of patterning the light-emitting materials has been adopted, and sandwiching between the anode and the cathode has been carried out. Development of a color display device having a structure of a light-emitting layer composed of the light-emitting material, particularly an organic EL (Electroluminescence) display device using an organic light-emitting material as a light-emitting material. [0003] Here, a conventional display device (organic EL display device) will be described with reference to the drawings. [0004] Figure 27 It is a schematic cross-sectional view showing a main part of a c...
