Problems solved by technology

In this way, during the film formation process of the other film layers on the side of the wiring 10 away from the substrate, the film layers located at the corner positions in the gap will have edge differences relative to the film layers located at the non-corner positions in the gap, resulting in The display panel shows unevenness (diagonal stains), which reduces product yield

Abstract

The invention provides a substrate, a preparation method of the substrate, a display panel and a mask plate, and relates to the technical field of display, and the phenomenon of non-uniform display of the display panel caused by terminal difference in the prior art can be improved. The substrate comprises a routing region; routes extending to a second direction from a first direction are arranged in the routing region; the first direction is crossed with the second direction; a gap between the routes has a height difference; the substrate further comprises a filling and leveling-up layer; and the filling and leveling-up layer comprises a filling and leveling-up pattern arranged at the gap between the routes, and is used for reducing the height difference of the gap between the routes.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a substrate and a preparation method thereof, a display panel, and a mask plate. Background technique [0002] With the development of display technology, LCD (Liquid Crystal Display, Liquid Crystal Display) display, OLED (Organic Light-Emitting Diode, Organic Light-Emitting Diode) display, flexible display, etc. are widely used in various fields. [0003] Wherein, in order to increase the aperture ratio of the substrate, usually according to the structure of the substrate, the traces on the substrate are reasonably arranged in the wiring area of ​​the non-display area of ​​the substrate. [0004] like figure 1 As shown, the wiring area of ​​the substrate is provided with traces 10 extending from a first direction to a second direction, the first direction intersects the second direction, and the traces 10 have corners. Wherein, in order to prevent the short circuit of the wir...
