Problems solved by technology
[0004] However, while improving the luminous efficiency and brightness of the OLED device, the microcavity effect often causes the electroluminescent spectrum of the OLED display device to change with the change of the observation angle, resulting in color shift when the OLED display device is observed at a large viewing angle.

The present invention provides an organic light-emitting display panel and an organic light-emitting display device, and relates to the technical field of display. The organic light-emitting display panel and the organic light-emitting display device are used to improve the color cast phenomenon appearing when the organic light-emitting display panel performs observation of a large visual angle inthe prior art. The organic light-emitting display panel comprises an array substrate and an organic light-emitting element, and the array substrate comprises a plurality of drive elements; the plurality of organic light-emitting elements are correspondingly arranged with the drive elements; each organic light-emitting element comprises one anode and one cathode and an organic function layer located between the anode and the cathode, wherein each cathode comprises one first cathode layer, the first cathode layer in each cathode of the at least one organic light-emitting element comprises a first area and a second area in a plane being parallel to the surface of the organic light-emitting display panel, and the materials of the first area and the second area are different in the refractiveindex of the visual light of the same wavelength. The organic light-emitting display panel is used for achieving frame display.
Description
【Technical field】 [0001] The present invention relates to the field of display technology, in particular to an organic light emitting display panel and an organic light emitting display device. 【Background technique】 [0002] Organic Light-Emitting Diode (hereinafter referred to as OLED) display panels are widely used in the field of display technology because of their many advantages such as active light emission, high contrast ratio, and no viewing angle limitation. In a traditional OLED display panel structure, in order to improve the luminous efficiency of the OLED device, a microcavity structure is usually used to enhance the luminescence of the OLED device. [0003] Since the microcavity can increase the emission rate at the resonant wavelength while suppressing the emission rate at the non-resonant wavelength, the microcavity structure can significantly narrow the emission spectrum, increase the peak value, and improve the brightness and luminous efficiency of OLED de...
