Abstract
A device and a method are provided to form a film by discharging a liquid material with a liquid discharge head or the like, such as an ink jet head, and which can reduce the unevenness resulting from variation of the amount of the discharged liquid material. To provide a device and a method to form a film by discharging a liquid material and which can increase process efficiency while suppressing the increase of costs, even if the liquid material is discharged onto various objects. When a color filter is manufactured, nozzles of a liquid discharge head discharge filter element materials onto filter-element-forming regions. In this instance, one color of the filter element materials is discharged while the liquid discharge head is swept in the longitudinal direction of a mother substrate. The other colors are discharged while the liquid discharge head is swept in the width direction of the mother substrate.
