Claim 6:
7. The method according to claim 6, wherein etching the flexible substrate to obtain the openings comprises:
etching the second barrier layer and the second organic layer to obtain second hole portions, wherein an etching gas used in etching the second organic layer etches the second organic layer at an etching rate greater than that for the second barrier layer, such that an orthographic projection of the second barrier layer on the support substrate covers an orthographic projection of the second organic layer on the support substrate; and
etching the first barrier layer and the first organic layer to obtain first hole portions, wherein an etching gas used in etching the first organic layer etches the first organic layer at an etching rate greater than that for the first barrier layer, such that an orthographic projection of the first barrier layer on the support substrate covers an orthographic projection of the first organic layer on the support substrate.
