COLOR FILTER MANUFACTURING METHOD AND APPARATUS, COLOR FILTER, AND DISPLAY DEVICE

摘要

PURPOSE: A color filter manufacturing apparatus and method is provided which enables to manufacture a color filter with less color unevenness in a short period of time, providing a display device and an apparatus which has the color filter and the display device. CONSTITUTION: A color filter manufacturing apparatus forms an array of colored portion of a color filter by discharging a plurality of inks from a plurality of discharge orifices at a predetermined density by using an ink-jet head having a plurality of discharge orifices, an ink chamber connected to the plurality of discharge orifices, an ink supply opening for supplying ink to the ink chamber, and an ink exit opening for exiting ink from the ink chamber. The color filter manufacturing apparatus comprises an ink flow generating device for generating a flow of ink from the ink supply opening to the ink exit opening in the ink chamber while discharging ink from the discharge orifices for coloring. The colored portion is formed when a variation rate of ink volume discharged from the plurality of discharge orifices for forming the array of colored portion is +/-3% or less
