US 2021/0066400 A1 · PREPARATION METHOD OF COLOR FILM LAYER, DISPLAY SUBSTRATE AND PREPARATION METHOD THEREOF

Abstract

A preparation method of a color film layer, a display substrate and a preparation method thereof. The display substrate includes a bearing layer and repeating units, each repeating unit including a green film layer, a red film layer and a blue film layer, which are provided on the bearing layer and directly contacting a first surface of the bearing layer. On a plane parallel to the first surface of the bearing layer, in each repeating unit, the red film layer is provided on a first side of the green film layer, the blue film layer is provided on a second side of the green film layer opposite to the first side; one of the red film layer and the blue color film layer covers part of the green film layer; one part of the green film layer does not overlap with the red film layer and the blue film layer.

(canceled)

A display substrate, comprising:

a base substrate;
and
a light-emitting element and a color film layer sequentially stacked on the base substrate;
wherein the color film layer comprises a first color film layer and a second color film layer provided on a side of the light-emitting element away from the base substrate, the second color film layer partially covers the first color film layer, and adhesion of the first color film layer is greater than adhesion of the second color film layer.

1 more element

A preparation method of a color film layer, the color film layer comprises a plurality of repeating units, and forming each of the repeating units comprises:

forming a first color film;
and
after forming the first color film layer, forming a second color film layer partially covering the first color film layer;
wherein adhesion of the first color film layer is greater than adhesion of the second color film layer;
the first color film layers of the plurality of repeating units are formed in a same patterning process, the second color film layers of the plurality of repeating units are formed in a same patterning process, and the third color film layers of the plurality of repeating units are formed in a same patterning process.
