Claim 26:
27. A method for manufacturing a display device, comprising:
forming an array of sub-pixels, a signal line and a first retaining wall structure on a base substrate; wherein the signal line includes a first conductive pattern and a second conductive pattern that are stacked on each other, the first conductive pattern is located between the second conductive pattern and the base substrate; the first retaining wall structure surrounds the array of sub-pixels and includes a first portion and a second portion; an orthographic projection of the first portion on the base substrate does not overlap with an orthographic projection of the signal line on the base substrate; an orthographic projection of the second portion on the base substrate is at least partially overlapped with an orthographic projection of the first conductive pattern on the base substrate; a boundary of the orthographic projection of the second portion on the base substrate, which is distal to the array of sub-pixels, is located between an orthographic projection of the array of sub-pixels on the base substrate, and a boundary of the orthographic projection of the first conductive pattern on the base substrate, which is distal to the array of sub-pixels; the orthographic projection of the second portion on the base substrate is partially overlapped with an orthographic projection of the second conductive pattern on the base substrate; a boundary of the orthographic projection of the second conductive pattern on the base substrate, which is close to the array of sub-pixels, is located between the orthographic projection of the array of sub-pixels on the base substrate, and a boundary of the orthographic projection of the second portion on the base substrate, which is close to the array of sub-pixels.
