Abstract
There is provided an active matrix type liquid crystal display, which hardly generates display unevenness incident to electrode dimensional fluctuation caused by variations resulting from the electrode formation process, and which is excellent in mass producibility and in high image quality. An active matrix type liquid crystal display using the horizontal electric field system, wherein dimensional fluctuation in the active elements and the stored capacity formation portion, and finish dimensional fluctuation in the electrode for applying an electric field to the liquid crystal layer occur simultaneously, and variations in effective driving voltage caused by fluctuation in the active element dimension act in a direction to compensate for variations in the optical quality caused by dimensional fluctuation of the electrode for applying the electric field.
