Abstract:
Provided is an orifice which promotes deaggregation and prevents particles from staying in one place. Also, provided are a liquid feeding device using the same, an application device, and a method for producing an optical film. To this end, the orifice comprises: an orifice main body; an inlet positioned at an entrance of the orifice main body; a shaft diameter part including a curved surface of which the radius of curvature connected to the inlet is 1-10 mm, and further including a primary inner lateral wall having a shaft diameter surface connected to the curved surface and axially crossing a narrow aperture at an angle of 120-180; and an enlarged diameter part connected to an outlet from the narrow aperture and including a secondary inner lateral wall enlarged at an angle of 2-10. The ratio of the diameter of the inlet to the diameter of the narrow aperture is 0.07-0.18.
