Abstract:
The invention relates to a liquid crystal display device including a first transistor, a plurality of sub-picture element electrodes formed in a picture element region, a control electrode formed in capacitance coupling with at least one of the plural sub-picture element electrodes, the control electrode being applied with a display voltage from the first transistor, and an auxiliary capacitance bus line held at a predetermined voltage level and constituting an auxiliary capacitance between the auxiliary capacitance bus line and the control electrode. A second transistor is provided between the sub-picture element electrode coupled with the control electrode by the capacitance coupling and the auxiliary capacitance bus line or between the sub-picture element electrode coupled with the control electrode by the capacitance coupling and the sub-picture element electrode connected to the first transistor.
