Abstract
A dc rejection circuit is provided between each output of a diode matrix circuit and a corresponding segment electrode in a liquid crystal display panel. The dc rejection circuit may comprise a very simple structure comprising a combination of a resistor and a capacitor thereby providing a liquid crystal display device which is inexpensive and yet ensuring a long service life.
