Abstract
A method of forming a color filter layer having a light-scattering effect. First, substrate is provided, and a color filter layer is coated on the substrate. Then, an exposure-and-development process is performed to pattern the color filter layer. Subsequently, the color filter layer is post-baked to render the color filter layer a rough surface to provide the light-scattering effect, wherein the color filter layer has a surface roughness index Rz in the range of 0.5 to 2.0 μm.
