Problems solved by technology
[0004] Embodiments of the present application provide a display panel and a manufacturing method thereof to solve the problem of the OLED display panel at the interface between the glass substrate and the light-emitting functional layer (specifically, the anode ITO in the light-emitting functional layer), as well as the interface between the glass substrate and the outside air. It is easy to produce total reflection, which causes a large light loss problem of the OLED display panel

Abstract
The invention discloses a display panel and a manufacturing method thereof. The display panel comprises a glass substrate, a one-dimensional photonic crystal layer arranged on the glass substrate, anda light-emitting function layer arranged on the one-dimensional photonic crystal layer; the one-dimensional photonic crystal layer comprises a plurality of crystal unit layers which are arranged in astacked mode; each crystal unit layer comprises a low-refractive-index sub-layer located on one side, close to the glass substrate, in the crystal unit layer and a high-refractive-index sub-layer located on one side, away from the glass substrate, in the crystal unit layer. According to the display panel, the one-dimensional photonic crystal layer is arranged between the glass substrate and the light-emitting function layer, light propagation is adjusted through the optical waveguide coupling effect of the one-dimensional photonic crystal layer, and therefore, light loss, caused by total reflection, of the display panel is reduced, and the light extraction efficiency of the display panel is improved; moreover, the one-dimensional photonic crystal layer is simple to manufacture, does not affect the manufacturing of other structures in the display panel, is also suitable for large-scale manufacturing, and is better in the application effect of large-area display.
Description
technical field [0001] The present application relates to the technical field of display panels, in particular to a display panel and a manufacturing method thereof. Background technique [0002] With the development of display technology, OLED display technology has been widely used because of its advantages such as self-luminescence, wide viewing angle, low power consumption, and extremely high response speed. For organic light-emitting diodes (OLEDs), its internal efficiency can basically be It reaches 100%, but because the refractive index matching of each medium layer is relatively poor, most of the light cannot be emitted into the air, and the light loss is relatively large. [0003] At present, in the structure of the OLED display panel, total reflection is easily generated at the interface between the glass substrate and the light-emitting functional layer (specifically, the anode ITO in the light-emitting functional layer), as well as at the interface between the gl...
