ABSTRACT:
During displacement relative to a substrate1,a coating die head emits coating liquid out of a slot12ato a surface of the substrate. The coating die head includes a lip12bhaving a lip surface12band a side having a side surface12c.A contact angle of the surface12cwith respect to the coating liquid is greater than a contact angle of the surface12bwith respect to the coating liquid. This configuration enhances stabilization of bead of the coating liquid during application process of the coating liquid, preventing stripes and steps from appearing in the coating layer. This coating die head makes it possible to carry out high precision coating required for fabrication of color filters for liquid crystal displays.
