Abstract
A liquid crystal display apparatus which stores a charge in the capacitor whereby the liquid crystal layer is continuously driven even if leak occurs therethrough, and which prevents any d.c. component from being applied to the liquid crystal layer, thus maintaining a display of clear, non-flickering constant image on the screen.
