Abstract

The invention provides a display panel, a manufacturing method thereof and a display device, and relates to the technical field of display. The invention provides the display panel. The display panelcomprises a substrate and a plurality of organic light-emitting devices arranged on the substrate, and at least two optical coupling layers which are arranged on the organic light-emitting device. Forany two adjacent optical coupling layers, the optical coupling layer far away from the substrate covers the optical coupling layer close to the substrate, and the refractive index of the optical coupling layer far away from the substrate is less than that of the optical coupling layer close to the substrate. Through at least two optical coupling layers, the display panel enables the wavelength difference of emergent rays to be reduced for light rays at different incident angles, so that the color cast caused by the visual angle is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel, a manufacturing method thereof, and a display device. Background technique [0002] As display devices are used more and more frequently in people's lives, OLEDs (Organic Light-Emitting Diodes, organic light-emitting diodes) with self-illumination, high contrast, fast response, and bendability have become the current display device industry. popular products, and are widely used in smart watches, mobile phones, TVs and other products. [0003] At present, in the manufacturing process of OLED display panels, the same optical coupling layer material is usually evaporated on the organic light-emitting devices to obtain the optical coupling layer, and the optical coupling layer covers all the organic light-emitting devices in the display panel. [0004] However, since the optical coupling layer covering all organic light-emitting devices is obtained by vapo...
