Abstract

A slit nozzle includes: a first head, a second head facing the first head; and a plurality of cores located between the first head and the second head, wherein the plurality of cores includes: a first core and a third core for coating a coating solution; and a second core located between the first core and the third core so that coating of the coating solution via the first core and the third core is achieved at different instants of time.

First claim

What is claimed is:

1. A slit nozzle comprising:
a first head having at least one injection port;
a second head facing the first head; and
a plurality of cores located between the first head and the second head,
wherein the plurality of cores comprises:
a first core for coating a first resin layer and a third core for coating a second resin layer;
a second core located between the first core and the third core so that coating via the first core and the third core takes place at different instants of time, and the second resin layer is coated on the first resin layer, and
a coating solution injected from a same injection port of the at least one injection port of the first head is configured to flow to both the first core to coat the first resin layer and the third core to coat the second resin layer.

2. The slit nozzle of claim 1 , wherein:
the first core is configured for sheet coating; and
the third core is configured for line coating.

3. The slit nozzle of claim 1 , wherein:
the first core comprises a first concave part having a first width at a bottom thereof, the first concave part being obtained by removing a lower portion of the first core.

4. The slit nozzle of claim 3 , wherein:
the second core comprises at least one through part.

5. The slit nozzle of claim 4 , wherein:
the at least one through part is located so that a partial region thereof overlaps the first concave part.

6. The slit nozzle of claim 4 , wherein:
the third core comprises a plurality of second concave parts each having a second width at a bottom thereof, the second concave parts being separated from each other by a first distance.

7. The slit nozzle of claim 6 , wherein:
the plurality of second concave parts are located so that a partial upper region thereof overlaps the at least one through part.

8. The slit nozzle of claim 6 , wherein:
the plurality of second concave parts are located so that a partial lower region thereof overlaps the first concave part.
