Abstract

A reflective and a transflective liquid crystal display device and a manufacturing method thereof are provided. The manufacturing method includes the following steps. First, a substrate structure of a reflective or a transflective liquid crystal display device is provided. Next, a reflection layer is formed over the substrate structure, a protection layer is formed over the reflection layer, and a photoresist layer is formed over the protection layer. Then, the photoresist layer is patterned to form a patterned photoresist layer, the protection layer is patterned to form a patterned protection layer, and the reflection layer is patterned to form a patterned reflection layer. Thereafter, the patterned photoresist layer is removed.
