Abstract
In a multi-gap semi-transmissive liquid crystal display device, the width of a black matrix () is made larger above the region between adjacent ITO transparent electrodes () and is made smaller above the region between adjacent Al reflective electrodes (). This enables a transmissive portion to offer a display with high contrast that does not suffer from afterimage or the like by shielding light from the domain lying between the adjacent pixels, and the reflective portion to offer a brighter display by increasing the aperture ratio thereof by making the black matrix width as small as possible or forming no black matrix.
