An underlying electrode is formed on nearly the entire surface of an opposing substrate and a color filter is formed on the underlying electrode. An overcoat layer is formed on the color filter. A stripe-shaped overlying electrode connected to the underlying electrode and extending to a part of each pixel area is formed on the overcoat layer, and an alignment film is formed on the overlying electrode. Formed on a TFT substrate are TFT's, pixel electrodes and another alignment film which covers the TFT's and pixel electrodes. A liquid crystal is provided between both substrates. When a drive voltage is applied between the underlying electrode and the pixel electrodes, the drive voltage is applied almost directly to the liquid crystal between the overlying electrode and the pixel electrodes, and a drive voltage dropped by the color filter and overcoat layer is applied to the liquid crystal between the underlying electrode and the pixel electrodes. Therefore, a plurality of areas with different alignment states are formed in each pixel and their optical characteristics are averaged, thus widening the view angle.
