Abstract

The invention provides an organic light-emitting display panel and a display device and particularly relates to the technical field of display. The organic light-emitting display panel comprises a substrate, an organic light-emitting device located on the substrate, a polarization structure located at a light outlet side of the organic light-emitting device, and a packaging structure, wherein thepolarization structure sequentially comprises a quarter-wave plate layer, a metal wire grid layer and a polarization substrate layer in a light outlet direction of the organic light-emitting device; and the packaging structure is located at one side, far away from the substrate, of the polarization substrate layer. A polarizer structure provided by the invention is designed into a stack structurecomprising the polarization substrate layer, the metal wire grid layer and the quarter-wave plate layer and is integrated into the organic light-emitting display panel, so that the transmittance of ashort wave band is also effectively improved while the thickness of the display panel is reduced; and meanwhile, light reflected from the organic light-emitting device directly enters a quarter-wave plate and the scattering phenomenon when the light is outside is eliminated, so that the organic light-emitting display panel is higher in polarization effect and greater in inhibiting effect on ambient light reflection.

Description

technical field [0001] The invention relates to the field of display technology, in particular to an organic light-emitting display panel and a display device. Background technique [0002] In the existing organic light-emitting display device, when external light is incident on the organic light-emitting display panel, the metal electrodes inside the panel will reflect the part of the incident light, resulting in problems such as low display contrast and color shift. In order to eliminate the influence of external light on the display, it is usually necessary to attach a polarizer to the organic light emitting display device. [0003] However, the thickness of existing polarizers generally can reach 100-250 μm, which is not easy to be integrated inside the display panel. At present, domestic panel manufacturers basically purchase polarizers through outsourcing and attach them to the outside of organic light-emitting display panels. Since the polarizers used in organic lig...
