An embodiment of the present invention discloses a polyimide coating method, which includes the following steps: providing a glass substrate and at least one nozzle; applying the nozzle to a polyimide solution onto the glass substrate to form a polyimide film; and moving the glass substrate to have the glass substrate pass through a roller that includes a printing plate so that the roller that includes the printing plate shapes the polyimide film uniformly distributed on the glass substrate to have a surface of the polyimide film formed on the glass substrate uniform and flat. The present invention also provides a polyimide coating device. The polyimide coating method and device of the present invention shorten coating time of polyimide, increase coating efficiency, and reduce coating cost.

The present invention is intended to solve a problem that a coating film has an uneven thickness in the case where a coating target 1 has a stepped portion extending in a predetermined direction on its coating surface. To solve the problem, a follow-up coating is performed along the stepped portion S extending in the predetermined direction after coating of the entire coating surface of the coating target 1 so that paint mist adheres more to a relatively-recessed side of the stepped portion S.
