Patent ID: 7453547

Claim:
A method for manufacturing an LCD panel comprising: providing a color filter substrate having a plurality of red pixel regions, green pixel regions, and blue pixel regions; providing an array substrate; forming a dielectric layer on the array substrate, the dielectric layer comprising a photosensitive dielectric layer having different thickness corresponding to the red pixel regions, the green pixel regions, and the blue pixel regions, wherein the step of forming the dielectric layer having different thickness comprises: forming the dielectric layer on the array substrate; and removing a portion of the dielectric layer to make the dielectric layer have different thickness corresponding to the red pixel regions, the green pixel regions, and the blue pixel regions, wherein the step of removing the portion of the dielectric layer comprises: partially removing the dielectric layer disposed in the red pixel regions, the green pixel regions, and the blue pixel regions so as to form a rough pattern in a reflection region of each red pixel region, each green pixel region, and each blue pixel region, and reduce the thickness of the dielectric layer disposed in a transmission region of each red pixel region, each green pixel region, and each blue pixel region; partially removing the dielectric layer positioned in the reflection region of each red pixel region, each green pixel region, and each blue pixel region so as to make the rough pattern in each reflection region form a rough structure, and reduce the thickness of the dielectric layer disposed in the transmission region of each red pixel region and each green pixel region; and partially removing the dielectric layer disposed in the reflection region of each red pixel region, each green pixel region, and each blue pixel region so as to form a contact hole in each reflection region, and reduce the thickness of the dielectric layer disposed in the transmission region of each red pixel region; assembling the color filter substrate and the array substrate; and providing a liquid crystal layer between the array substrate and the color filter substrate.
