Abstract

PURPOSE: To reduce the electric power consumed by an indication device by a method wherein a memory circuit retaining memories logically is provided at the intercepting point of signal lines and selection lines in plural formed like a matrix.
CONSTITUTION: A cell of one picture element is formed of transmission gates TG6 and 9, inverters 6 and 8 and a capacitor 5 formed of the liquid crystal beld between electrodes which are provided at each intercepting point of two selection line 1 and signal line 2 formed like a matrix. At the time of writing-in, the TG6 is turned on, twovalued data of the signal line 2 are written in and the TG6 is turned off, and concurrently the TG9 is turned on, the data are latched by the inverters 7 and 8, and the output voltage of the inverter 7 is impressed on the liquid crystal. Accordingly, the capacitor for maintaining signals is made unnecessary, while the consumed electric power can be reduced, and further the contrast property can be made excellent.
