Abstract
A method of manufacturing a color filter substrate includes: forming a plurality of first members, a plurality of second members and a plurality of third members, where each of the first members, the second members and the third members has a pillar shape extending in a direction; stacking the first members, the second members and the third members on one another; forming a preform by inserting the stacked first members, second members, and third members into a cane; forming a stick member from the preform via a drawing process by applying heat to the preform inserted into the cane; and slicing the stick member.
