Abstract

The present application provides a display panel and a manufacturing method thereof. The display panel includes: a first substrate, a second substrate arranged opposite to the first substrate, and a blue light emitting layer and a color conversion layer stacked between the first substrate and the second substrate The color conversion layer is disposed on the light-emitting side of the blue light emitting layer, the color conversion layer includes a plurality of diffusion pixel units, and the diffusion pixel units include a matrix and first scattering particles and Second scattering particles, the first scattering particles are located on the side of the color conversion layer close to the blue light emitting layer, the second scattering particles are located on the side of the color conversion layer away from the blue light emitting layer, the first scattering particles The molar concentration of one scattering particle is smaller than the molar concentration of the second scattering particle, and the particle diameter of the first scattering particle is larger than the particle diameter of the second scattering particle.

Description

technical field [0001] The present application relates to the field of display, and in particular, to a display panel and a manufacturing method of the display panel. Background technique [0002] It is known that an organic light-emitting diode display panel (Organic Light-Emitting Diode, OLED) uses a blue OLED vapor-deposited on the whole surface as a self-luminous source, and is matched with a color conversion film prepared by a wet method, so as to realize full-color display. However, due to factors such as interference between adjacent color conversion materials, poor light absorption and light extraction rate, etc., the light efficiency of the conversion film is low, which directly affects the energy utilization and display brightness of the display device. SUMMARY OF THE INVENTION [0003] In view of this, the present application aims to provide a display panel capable of improving light conversion efficiency and a manufacturing method thereof. [0004] The present...
