Embodiment Construction

[0020] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention more clear, various implementation modes of the present invention will be described in detail below in conjunction with the accompanying drawings. However, those of ordinary skill in the art can understand that, in each implementation manner of the present invention, many technical details are provided for readers to better understand the present application. However, even without these technical details and various changes and modifications based on the following implementation modes, the technical solution claimed in this application can also be realized.

[0021] The first embodiment of the present invention relates to a display panel 100, such as figure 1 As shown, it includes: a substrate 11, a first sacrificial layer 12 on the substrate 11, and a patterned first metal layer 13 on the first sacrificial layer 12. The first sacrificial layer 12 includes severa...

Abstract

The embodiments of the invention belongs to the technical field of display and discloses a display panel and a preparation method thereof. The display panel includes a substrate, a first sacrificial layer located on the substrate and a patterned first metal layer located on the first sacrificial layer; the first sacrificial layer comprises a plurality of first areas and second areas adjacent to the first areas; and the patterned first metal layer is located on the first areas and expose the second areas. The invention further provides a preparation method of the display panel. With the displaypanel and the preparation method thereof provided by the invention adopted, a metal residue problem can be improved, and the yield of devices is improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a display panel and a manufacturing method thereof. Background technique [0002] OLED (organic light emitting diode, organic light-emitting diode) has excellent characteristics such as self-luminescence, low energy consumption, wide viewing angle, rich color, and fast response. next-generation technology. OLED display panels need to go through many processes during the manufacturing process. For example, for thin film transistor (Thin Film Transistor: TFT) driving process, generally a dry etching process is used to etch the metal layer to form a patterned metal layer. [0003] The inventors have found that there are at least the following problems in the prior art: due to the influence of factors such as the existence of particles in or on the metal layer, and the presence of residual glue in the photoresist after the exposure and development process,...
