  • ORGANIC LIGHT-EMITTING DISPLAY DEVICE AND DISPLAY APPARATUS
    Publication number: 20200203618
    Abstract: An organic light-emitting display device (100). A functional structure layer (130) of the organic light-emitting display device (100) comprises a hole injection layer (131), a first hole transport layer (1321), a second hole transport layer (1322), an organic light-emitting layer (133), an electron transport layer (134) and an electron injection layer (135) which are sequentially laminated on a first electrode (110). The highest occupied orbital energy level of the material of the first hole transport layer (1321) is less than the highest occupied orbital energy level of the second hole transport layer (1322). A triplet state energy level of the material of the second hole transport layer (1322) is greater than 2.5 eV. The organic light-emitting layer (133) comprises a main light-emitting material, and the main light-emitting material comprises a thermal activation delay fluorescent material.
