Abstract:
A structure of a multi-layered thin film layer, which is applicable to a substrate of a liquid crystal display, wherein the substrate comprises a pixel cell area and a peripheral circuit area, which further comprises a plurality of pixel cells and metal layers, respectively, the structure comprising:a first protective layer in the peripheral circuit area to cover the metal layers; a plurality of pad spacers in the pixel cell area and the peripheral circuit area, wherein the pad spacers are higher than the first protective layer, and a second protective layer in the pixel cell area to cover the pixel cells, wherein the second protective layer has a high reflectivity allowing a transmission of light to reach the pixel cells and a reflection of light, wherein the pad spacers are formed with a first oxide layer, a silicon nitride layer and a second oxide layer.
