Patent ID: 8335046

Claim:
A method of manufacturing a color filter substrate, the method comprising: forming a first color photoresist layer on a base substrate having a display area and having a peripheral area surrounding the display area; forming a first color filter in the display area of the base substrate and forming a first dummy pattern in the peripheral area and surrounding the display area, where said forming of the first color filter and of the first dummy pattern comprises patterning the first color photoresist layer, wherein the display area has a polygon shape, the first dummy pattern defines there-within a major first opening with a first shape that conforms to and surrounds the polygon shape of the display area and where the first dummy pattern substantially defines for itself an outer boundary with a second shape that is different from the first shape; forming a second photoresist layer on the base substrate on which the first color filter and the first dummy pattern are formed; and forming a second color filter formed in the display area by patterning the second color photoresist layer.
