Abstract:
1. A method for fabricating a color filter substrate for a liquid crystal display, comprising the steps of: forming a black matrix on an insulating substrate; forming a color filter on the black matrix; forming a common electrode on the color filter; depositing an insulating layer onto the common electrode; and patterning the insulating layer in a single selective light exposure step to thereby form a first protrusion with a first height, and a second protrusion with a second height, the second height being greater than the first height, wherein a first bottom level of the first protrusion is different from a second bottom level of the second protrusion from the insulating substrate and the first protrusion has a width of about 4-14μm and the second protrusion has a width of about 15-45μm.
