Document Type and Number:
WIPO Patent Application WO/2020/211265
Kind Code:
A1
Abstract:
A display panel and a display device. The display panel comprises: a data line, a scan line, a driving current line, an anode (301), a pixel defining layer (302), an organic flat layer (303), an inorganic protective layer (304), and a cathode (305). The organic flat layer (303) is provided with recessed regions having different heights so that corresponding recessed regions (307) are formed for a light-emitting region (306) above the organic flat layer (303). The structure can be driven by a small current density to achieve the required brightness, thereby efficiently improving the service life of the display panel and the display device.
