Abstract: A drying device may include: a body defining a drying space therein; a heater disposed in the drying space to face a surface of the film moving in the drying space, including an inner tube and an outer tube, and configured to radiate electromagnetic waves through the outer tube, wherein a surface temperature of the outer tube is maintained at 200 degrees or less; and a reflector at least partially covering the heater and configured to reflect at least a part of the electromagnetic waves radiated from the outer tube of the heater toward the film moving in the drying space. The heater may be configured to radiate electromagnetic waves in a wavelength band below a predetermined wavelength to the film and is configured to absorb electromagnetic waves in a wavelength band equal to or above the predetermined wavelength.

Abstract: A drying device configured to dry a resin film including a solvent, the drying device may include: a housing; a partition disposed in the housing and partitioning a space in the housing into a first space and a second space; a conveyor configured to convey the resin film in the first space; a first heater disposed in the second space and configured to radiate electromagnetic waves to the resin film being conveyed by the conveyor; and a window disposed in the partition and configured to allow the electromagnetic waves radiated from the first heater to penetrate therethrough. The first heater may be configured to radiate electromagnetic waves in a wavelength band below 4.0 μm to the resin film and to absorb electromagnetic waves in a wavelength band of at least 4.0 μm or more.
