Abstract

The invention discloses a display panel and a display device. The display panel comprises a substrate, a light emitting unit on the substrate, and a packaging layer which is positioned on one side, far away from the substrate, of the light-emitting unit, wherein the packaging layer comprises a first inorganic film layer, a first auxiliary film layer and an organic film layer which are stacked on the light emitting unit, an absolute value of the difference between a refractive index of the first inorganic film layer and a refractive index of the first auxiliary film layer is smaller than or equal to 0.05, and an extinction coefficient of the first auxiliary film layer to visible light is smaller than that of the first inorganic film layer to visible light. The display panel is advantaged inthat the display effect of the display panel can be improved on the premise of ensuring the light emitting quantity of the display panel.

Description

technical field [0001] The present invention relates to the display field, in particular to a display panel and a display device. Background technique [0002] The organic light emitting diode (Organic Light Emitting Diode, OLED) display panel 100 display has advantages such as high color gamut, flexibility, fast response speed, etc., and its market share increases year by year. Users have higher and higher requirements for the display effect of OLED panels. However, in OLED display panels, since the thickness of each film layer of the device and package fluctuates with the evaporation cycle, the uniformity of film thickness will aggravate the dispersion of OLED viewing angle characteristics, and problems such as blue and pink viewing angles will appear. [0003] Therefore, there is an urgent need to provide a new display panel and a display device. Contents of the invention [0004] Embodiments of the present invention provide a display panel and a display device, aimin...
