Abstract

The embodiments of the present invention disclose an organic light emitting display panel and an organic light emitting display device. The organic light emitting display panel includes a first substrate, a first electrode layer, a first hole transport layer, a second hole transport layer, a plurality of light-emitting devices, an electron transfer layer and a second electrode layer; the first electrode layer includes a plurality of first electrodes; the second hole transport layer includes a plurality of hole transport units, wherein the hole transport units are respectively corresponding to the first electrodes; the light-emitting devices are respectively corresponding to the hole transport units; the light-emitting devices comprise m kinds of colors, wherein m is an integer greater than or equal to 3; hole transport units corresponding to light-emitting devices of at least one kind of color are made of a mixture of at least two kinds of hole transfer materials; and the lowest unoccupied molecular orbit of at least one kind of hole transfer material in the at least two kinds of hole transfer materials is higher than that of corresponding light-emitting devices. With the organic light emitting display panel provided by the embodiments of the present invention adopted, the false turn-on phenomenon of sub-pixels can be alleviated.

Description

technical field [0001] Embodiments of the present invention relate to organic light emitting diode technology, and in particular to an organic light emitting display panel and an organic light emitting display device. Background technique [0002] Organic light-emitting diode (Organic Light-Emitting Diode, OLED) display panel is a self-luminous display device with organic thin film as illuminant, which has the advantages of ultra-thin, high brightness, high luminous efficiency and good shock resistance. In an organic light emitting display panel, a pixel defining layer is usually used to define each sub-pixel area. In order to improve the encapsulation effect of each sub-pixel, a spacer can also be provided on the pixel defining layer between any two adjacent sub-pixels. [0003] However, the organic light-emitting display panel manufactured by the prior art has the phenomenon of stealing light from adjacent sub-pixels. Such as figure 1 Shown is a structure of an organic l...
