Abstract

The invention provides a display panel and a manufacturing method thereof. The display panel includes: a first substrate, a second substrate which is arranged opposite to the first substrate, and a blue light emitting layer and a color conversion layer which are arranged between the first substrate and the second substrate in a stacked mode. The color conversion layer is arranged on the light emitting side of the blue light emitting layer; the color conversion layer comprises a plurality of diffusion pixel units; each diffusion pixel unit comprises a matrix, first scattering particles and second scattering particles, wherein the first scattering particles and the second scattering particles are dispersed in the matrix. The first scattering particles are positioned on one side, close to theblue light emitting layer, of the color conversion layer; the second scattering particles are located on the side, away from the blue light emitting layer, of the color conversion layer, the molar concentration of the first scattering particles is smaller than that of the second scattering particles, and the particle size of the first scattering particles is larger than that of the second scattering particles.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel and a method for manufacturing the display panel. Background technique [0002] An organic light-emitting diode display panel (Organic Light-Emitting Diode, OLED) is known that uses a blue-light OLED evaporated on the entire surface as a self-emitting light source, and is combined with a color conversion film prepared by a wet method to achieve full-color display. However, due to factors such as interference between adjacent color conversion materials, poor light absorption and light extraction rate, the light efficiency of the conversion film is low, which directly affects the energy utilization and display brightness of the display device. Contents of the invention [0003] In view of this, the purpose of the present application is to provide a display panel capable of improving light conversion efficiency and a manufacturing method thereof. [0004] The present...
