Patent ID: 8728950

Claim:
A coating method of coating a coating solution on a substrate employing a slit-type die coater comprising a lip tip and, provided at the lip tip, a slit outlet and at least one groove facing a coating region in a coating width direction, the slit outlet and the groove being alternately provided, the method comprising the steps of: allowing the lip tip of the slit-type die coater to be close to the substrate; ejecting a coating solution from the slit outlet to form a bead between the lip tip and the substrate, where the coating solution is not ejected from the groove; and coating on the substrate the ejected coating solution while relatively moving the slit-type die coater and the substrate, thereby forming on the substrate at least two coating layers in a stripe shape separated from each other and arranged side by side, and a non-coating portion between the two coating layers wherein the coating is carried out at a pressure at the slit outlet being negative or zero.
