ABSTRACT:
A circuit configuration is simplified to enable a color display of a high aperture ratio and multiple gradations to have no malfunctionA first transistor pair composing a first inverter and a second transistor pair composing a second inverter, while bridging alternating power sources φp and φn, are caused to act as an output circuit to a pixel electrode. Diodes D1and D2having the same forward direction as the conduction direction of the first transistors are inserted into the series circuit of the first transistor pair, and the common node of the diodes is connected with the output of a switching transistor. A capacitor is connected between a common node of control electrodes of the second transistor pair and a series connection intermediate node of the second transistor pair so that the written state of data is controlled by making use of charges stored in the capacitor.
