Abstract
An LCD includes a first substrate, a transparent electrode formed on the first substrate, a coupling electrode connected to the transparent electrode, a reflective electrode formed on the first substrate and separated from the transparent electrode, an auxiliary electrode formed on the first substrate and connected to the reflective electrode where the auxiliary electrode overlaps the coupling electrode with an interposing dielectric layer, a second substrate facing the first substrate, and a protrusion formed on the second substrate. The LCD utilizes the protrusion formed at a reflective area and an auxiliary capacitor connected to a reflective capacitor in series to accord compatible reflectance and transmittance curves for the reflection area and the transmission area having the same cell gaps. As a result, the light efficiency of the LCD becomes higher and the viewing angle of the LCD becomes wider.
