ABSTRACT:
A semi-transmission type liquid crystal display that maximizes the luminance in reflection mode and transmission mode. The liquid crystal display comprises a lower substrate with thin film transistors, an opposite substrate facing the lower substrate, a liquid crystal layer between the lower substrate and the opposite substrate, a reflection electrode formed in a reflection area of the lower substrate, a transparent electrode formed in a transparent area of the lower substrate, a common electrode formed on the opposite substrate, and a drive circuit for applying a voltage between the reflection electrode and the transparent electrode and the common electrode. The potential difference between a drive voltage applied to that surface of the lower substrate which contacts the liquid crystal layer and a drive voltage applied to that surface of the opposite substrate which contacts the liquid crystal layer is lower in the reflection area than in the transparent area.
