Problems solved by technology

[0005] This application provides a display panel and its manufacturing method to solve the problem that in the prior art, large-size OLED display screens often use inkjet printing to form luminescent materials. When forming a pixel definition layer, the material of the pixel definition layer often uses For organic materials with high transmittance, there is no light-shielding layer between two adjacent light-emitting units of different colors, resulting in the technical problems of color mixing of different colors and poor display effect

Abstract

The invention discloses a display panel and a manufacturing method thereof. The display panel comprises an array substrate, an anode layer located on the array substrate, a shading layer located on the anode layer and a cathode layer located on the shading layer, wherein the shading layer comprises a plurality of first shading units and a plurality of second shading units, the first shading unitsare perpendicular to the second shading units, and the second shading units are located between every two adjacent first shading units; the two adjacent second shading units and the two adjacent firstshading units form an opening, the anode layer is exposed through the opening, and the opening is filled with a light emitting unit, wherein the thickness of the second shading unit is smaller than that of the first shading unit, and the thickness of the second shading unit is larger than or equal to that of the light-emitting unit. According to the invention, the shading layer is formed by usingthe shading material to form a pixel definition layer, so that the color mixing phenomenon among the light-emitting units with different colors is avoided, and the display effect is improved.

Description

technical field [0001] The present application relates to the field of display, in particular to the field of display technology, and in particular to a display panel and a manufacturing method thereof. Background technique [0002] With the improvement of living standards, large-size display screens are becoming more and more popular in daily life. OLED (Organic Light-Emitting Diode, organic light-emitting semiconductor) display screens are more and more widely used in large-size display screens due to their high display color. [0003] In the prior art, large-size OLED display screens often use inkjet printing to form luminescent materials. When forming the pixel definition layer, since the material of the pixel definition layer often uses organic materials with high transmittance, two adjacent pixels of different colors There is no light-shielding layer between the light-emitting units, resulting in color mixing of different colors of light and poor display effect.
