PURPOSE: A device and a method for printing an alignment film are provided to widen the contact area between a substrate and a polyimide solution by using a polyimide mask of which aperture rate is reduced to 5-25%, thereby realizing the high resolution. CONSTITUTION: A device for printing an alignment film includes a dispenser for dropping a polyimide solution(301) as an orientation solution supplied from a supply line, a doctor roll for spreading the orientation solution by a uniform thickness and an anilox roll engaged with the doctor roll, a printing roller for transferring the orientation solution supplied from the anilox roll to a substrate and attached with a polyimide mask(410) on a surface thereof, and a printing table for supporting the substrate. The mask has an aperture rate of 5-25%.
