Abstract
An exemplary method for fabricating a transflective liquid crystal display is provided. The transflective liquid crystal display includes a substrate () having a transmission region () and a reflection region (). The method includes: forming a transparent electrode layer (), a buffer layer (), and a reflective metal layer () on the substrate; forming a photo-resist layer () on the reflective metal layer; providing a photo-mask () comprising a first portion corresponding to the transmission region and a second portion corresponding to the reflection region, transmittance of the first portion being greater than transmittance of the second portion; exposing the photo-resist layer using the photo-mask and developing the exposed photo-resist layer; ashing the residual photo-resist in the transparent region; etching the reflective metal layer and the buffer layer in the transmission region; and removing the residual photo-resist in the reflection region.
