ABSTRACT:
A liquid crystal display capable of freely changing between the state of having a large viewing angle and the state of having a small viewing angle according to one's need, and an electronic apparatus using the liquid crystal display. A pair of substrates having respective surfaces opposed to each other are provided and a liquid crystal is provided between the substrates. A common electrode and an alignment film are successively formed on the opposed surface of one of the pair of substrates. A multiplicity of pixel electrodes are provided on the opposed surface of the other substrate so as to cover display regions of the liquid crystal. An electroconductive black matrix is provided on the other substrate while being electrically insulated from the pixel electrodes, the black matrix being formed at peripheral portions of the pixel electrodes and over non-display regions of the liquid crystal. Another alignment film is provided over the pixel electrodes and the black matrix. A switch is provided to divide a pixel region formed corresponding to each pixel electrode into two by applying a potential to the black matrix. The switch changes the two pixel regions formed corresponding to each pixel electrode into one when no potential is applied to the black matrix.
