Description

technical field [0001] Embodiments of the present invention relate to display technologies, and in particular to an organic light emitting display device, a manufacturing method thereof, and an organic light emitting display device. Background technique [0002] A microcavity structure is formed between the positive and negative electrodes of the top-emitting organic light-emitting display device. The microcavity structure has a microcavity effect, such as increasing the light intensity at the emission wavelength of the microcavity structure, that is, the luminescent center, and narrowing the emission peak spectrum. At the same time, the emission peak wavelength can be changed, and the emission peak wavelength, intensity, and half-width of the emission peak can be adjusted, that is, the microcavity effect of the top-emitting organic light-emitting display device can improve color purity, luminous efficiency, and luminous intensity. While the length of the microcavity is an i...
