Abstract
An active matrix-type liquid crystal display device which is capable of realizing a dot inversion driving by disposing H drivers on both sides of the liquid crystal panel, while using existing H driver circuits which output odd output data and even output data at opposite polarities to each other. The first and second H drivers, which output odd output data and even output data at opposite polarities to each other, are disposed facing each other on both sides of the liquid crystal panel, in order to realize an active matrix-type liquid crystal display device which is conducted by the dot inversion driving. Data electrodes of said liquid crystal display device are taken out for every two lines or every integer times of two lines and the thus taken out data lines are connected alternately to the first and second driver circuits.
