Abstract
The liquid crystal display comprises a first substrateincluding a gate bus line, a data bus line, a thin film transistorformed near an intersection between the gate bus lineand the data bus line, and a pixel electrodeincluding a transmission electrodeelectrically connected to the thin film transistorand a reflection electrodeelectrically connected to the transmission electrode; a second substrateopposed to the first substrateand including an opposed electrodeopposed to the pixel electrode; and a liquid crystal layersealed between the first substrateand the second substrate. The reflection electrodeis formed over another gate bus linewhich is different from the gate bus line, with an insulation layerformed therebetween. The decrease of a voltage applied between the reflection electrodeand the opposed electrodecan 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.
