Patent number: 11145691Abstract: Provided are an organic light-emitting display panel and a display device, for improving the light extraction efficiency of OLED display panel. The organic light-emitting display panel includes an array substrate having a plurality of driving elements, and a plurality of organic light-emitting components. Each light-emitting component includes an anode, a cathode and an organic functional layer arranged between the anode and the cathode. The organic functional layer includes a hole transmission region, a light-emitting layer, and an electron transmission region stacked in a sequence from the anode to the cathode. With respect to visible light having a certain wavelength, a refractive index of the light-emitting layer is less than a refractive index of the electron transmission region, and the refractive index of the light-emitting layer is less than a refractive index of the hole transmission region. The above organic light-emitting display panel is applicable to the display device.Type: GrantFiled: December 5, 2018Date of Patent: October 12, 2021Assignee: SHANGHAI TIANMA AM-OLED CO., LTD.Inventors: Xiaoqian Sun, Xiangcheng Wang, Jinghua Niu, Weili Qiao, Jun Lin, Lei Wen, Ping An
