Abstract

The invention is suitable for the technical field of display, and provides a display panel which comprises a first substrate and a second substrate which are oppositely arranged. The plurality of micro LEDs are arrayed on the first substrate at intervals; the plurality of color converters are arranged on the second substrate and are opposite to the micro LEDs respectively, each color converter comprises a color filter film and a quantum dot layer which are stacked, and the quantum dot layer is used for changing the wavelength of light; the shading part is located between the adjacent color converters, the shading part at least comprises a first color resistance layer and a second color resistance layer which are sequentially arranged on the second substrate in an overlapped mode and are different in color, and the shading part is right opposite to a gap between the adjacent micro LEDs. The invention further provides a manufacturing method of the display panel. According to the display panel and the display panel manufacturing method provided by the invention, color crossing between the sub-pixels can be effectively avoided, the manufacturing process is simple, and the cost is relatively low.

Description

technical field [0001] The present application belongs to the field of display technology, and in particular relates to a display panel and a method for manufacturing the display panel. Background technique [0002] Due to its performance advantages of high color saturation, quantum dot display has become the next generation of new display innovation technology. At present, display devices based on quantum dot materials usually include monochromatic micro LEDs or mini LEDs and quantum dot color conversion layers. With the development of technology, the chip size of micro LED or mini LED and the spacing between chips are getting smaller and smaller. In order to prevent color crossover between different sub-pixels, in the process of making the quantum dot color conversion layer, it is usually necessary to make Quantum dot barrier layer, however, the production of quantum dot barrier layer will add a yellow light process, the process is more cumbersome and the cost is higher. ...
