摘要： The embodiment of the present application provides a display panel and a manufacturing method thereof. The display panel comprises a light-emitting device layer, a first optical structure layer, a second optical structure layer and an anti-reflection layer. The light-emitting device layer comprises light-emitting diodes and a retaining wall. The second optical structure layer is filled in the opening areas. Meanwhile, a refractive index of the second optical structure layer is greater than a refractive index of the first optical structure layer. The light extraction rate and display effect are improved with the optical structure layers with different refractive indexes and the retaining wall.

摘要： A display panel, a method for manufacturing the same, and a display terminal are provided. The display panel includes an array substrate, a light-emitting device layer, and a color resist layer. The light-emitting device layer is disposed on the array substrate and includes a red light-emitting device, a first blue light-emitting device, and a second blue light-emitting device. The color resist layer is disposed on the light-emitting device layer and includes a red color resist, a blue color resist, and a green color conversion unit. The red color resist is disposed corresponding to the red light-emitting device. The blue color resist is disposed corresponding to the first blue light-emitting device. The green color conversion unit is disposed corresponding to the second blue light-emitting device and is configured to convert a light emitted by the second blue light-emitting device into a green light.
