A method to form a film by discharging a liquid material onto the surface of an object with a liquid discharge device to manufacture a color filter, the method comprising: first discharging a plurality of droplets of the liquid material from a row of ink jets comprising an ink jet head at a first row position onto the surface of the object while the liquid discharge device sweeps with the same first row position over the object in a first sweeping direction with respect to the object, along the surface of the object; and second discharging a plurality of droplets of the liquid material from a row of ink jets comprising an ink jet head at a second row position onto the surface while the liquid discharge device sweeps with the same second row position over the object in a second sweeping direction different from the first sweeping direction with respect to the object, along the surface of the object wherein each of the first and second sweeping directions have different x and y directions and further the rows of ink jets for each sweep are not parallel to each other during successive sweeps.
