Liquid crystal is encapsulated between two transparent substrates 16, 17. Pixel electrodes 13 are formed on the inner surface of the transparent substrate 17 in the form of a matrix while a common electrode 12 is formed on the inner surface of the transparent substrate 16. Each pixel electrode 13 is divided into subpixel electrodes 13.sub.1, 13.sub.2. The subpixel electrode 13.sub.1 is connected to the drain of a thin film transistor 21 formed adjacent the subpixel electrode to apply driving voltage to the electrode. The subpixel electrode 13.sub.2 is supplied with capacitance-divided driving voltage through a capacitor comprising the electrode 13.sub.1, and a control capacitor 15 connected thereto with an insulation layer 14 interposed therebetween. Each of the subpixel electrodes 13.sub.1, 13.sub.2 are divided into two domains on which are formed alignment layers 41a, 41b, 42a, 42b, in opposition to alignment layers 43a, 43b, 44a, 44b formed on the common electrode 12. One of the opposed alignment layers is adapted to impart to the liquid crystal a pretilt angle greater than the other alignment layer. One of a pair of adjacent orientating films in the same plane is adapted to impart to the liquid crystal a pretilt angle greater than the other orientating film.
