Method of manufacturing a rugged reflector for liquid crystal display devices
A method of manufacturing a reflecting substrate in a liquid crystal display device is disclosed, comprising the steps of: (a) providing a substrate having a first metal layer, wherein the first metal layer is formed with at least one soft metal or the alloys thereof; and (b) forming an aluminum nitride layer on the first metal layer. The method of the present invention is capable of forming a rugged, shining, reflective layer on a transflective, or a reflection type TFT LCD with simple steps and low cost.
1. A method of manufacturing a rugged reflecting layer for diffusion an incident light in a reflective-type liquid crystal display device, comprising the steps of:
(a) providing a transparent substrate having a first metal layer thereon, wherein the first metal layer is formed with at least one soft metal or the alloys thereof;
(b) forming a layer of aluminum nitride on the first metal layer, wherein a rugged interface is formed between the first metal layer and the layer of aluminum nitride while forming the layer of aluminum nitride; and
(c) removing the layer of aluminum nitride on the first metal layer.
