ABSTRACT:
The liquid crystal display comprises a first substrate2including a gate bus line12a, a data bus line28, a thin film transistor18formed near an intersection between the gate bus line12aand the data bus line28, and a pixel electrode52including a transmission electrode32aelectrically connected to the thin film transistor18and a reflection electrode48belectrically connected to the transmission electrode32a; a second substrate4opposed to the first substrate2and including an opposed electrode68opposed to the pixel electrode52; and a liquid crystal layer6sealed between the first substrate2and the second substrate4. The reflection electrode48bis formed over another gate bus line12bwhich is different from the gate bus line12a, with an insulation layer40formed therebetween. The decrease of a voltage applied between the reflection electrode48band the opposed electrode68can be prevented while the space which can be not used as the transmission region can be utilized. Thus, the area decrease of the transmission part is prevented while the area of the reflection part can be increased, whereby a reflective transmission type liquid crystal display of higher display quality can be provided.
