Abstract
A reflection type liquid crystal display provided with a reflective layer, a coplanar gate electrode, a color filter layer and a transparent pixel electrode and a manufacture method thereof. The reflection type liquid crystal display can be manufactured on the same manufacture line as that of a transmission type liquid crystal display. In order to realize this manufacture method, a photolithography mask capable of forming both a gate electrode and a reflective layer, and a photolithography mask capable of forming only the gate electrode are prepared, and by using either one of the masks, the reflection type liquid crystal display in which both the gate electrode and the reflective layer are formed on a transparent insulation substrate, and the transmission type liquid crystal display in which only the gate electrode is formed, are selectively manufactured.
