Display module, manufacturing method thereof and touch display device

A method for manufacturing a display module, the display module comprising a display panel, a touch panel, and a bonding component, wherein the touch panel is on a display side of the display panel, and the bonding component is between the display panel and the touch panel, and configured to bond the display panel and the touch panel,

• wherein, upon forming the touch panel, the manufacturing method comprises:
• forming a wiring precursor layer;
• coating photoresist on the wiring precursor layer;
• exposing the photoresist through a mask, and developing the exposed photoresist;
• etching the wiring precursor layer to form a plurality of wirings by using the photoresist pattern obtained after development as a mask, wherein, in a direction perpendicular to the extending direction of the wirings, a maximum space between two adjacent wirings of the plurality of wirings is not greater than 10λ, where λ is the wavelength of light emitted by the display panel;
• and
• removing the photoresist.
