Abstract
An organic light-emitting display panel is provided that improves luminous efficiency and luminescent color by adjusting the difference in film thickness between layers of different luminescent colors, such as intermediate layers, when the intermediate layer and light-emitting layers are formed by a wet method. By varying the film thickness of an interlayer insulation film, which is a lower layer of an organic light-emitting element, the volume of a contact hole is varied by color, thereby adjusting the volume of a concavity in each anode plate. When ink that includes material for the intermediate layer, or like, is sprayed by an inkjet method, the film thickness of the intermediate layer, or like, changes in accordance with the amount of ink filing the concavity. Therefore, by adjusting the difference in volume between concavities of different colors, the difference in film thickness between the intermediate layers, or like, is finely adjusted.
