Abstract
The invention provides an OLED display panel and manufacturing method thereof. The manufacturing method of OLED display panel of the invention forms a first scattering layer on the thin film encapsulation layer, a quantum dot layer on the first scattering layer, and a second scattering layer on the quantum dot layer. The first scattering layer extracts light from the OLED device, so that the light totally reflected by OLED device through thin film encapsulation layer is emitted as much as possible; the light extracted by the first scattering layer reaches the quantum dot layer. The quantum dots are excited to perform light color matching to emit light of desired color. Since the light excited by quantum dot layer is dispersed, the second scattering layer extracts the light excited by the quantum dot layer in an orderly manner, so that the OLED display panel emits light uniformly, thereby improving luminous efficiency.
