Patent ID: 7212342

Claim:
A structure of a color filter for use in a liquid crystal display, the color filter structure comprising: a substrate; an indium tin oxide layer on the substrate; a silicon nitride layer on the indium tin oxide layer, wherein a value of an RF power used for growing the silicon nitride layer is a first power value; an amorphous silicon layer located on the silicon nitride layer; an n-type silicon layer located on the amorphous silicon layer; and a metal layer on the n-type silicon layer, wherein a light is emitted into the color filter from the substrate, and after sequentially passing through the substrate, the indium tin oxide layer, the silicon nitride layer, the amorphous silicon layer, and the n-type silicon layer, the light is reflected by the metal layer to be transmitted along an original path for leaving the color filter, wherein the light is absorbed and interfered with by the indium tin oxide layer, the silicon nitride layer, the amorphous silicon layer and the n-type silicon layer, the light being filtered into a specific color light after being emitted from the color filter.
