Abstract:
In a multi-gap semi-transmissive liquid crystal display device, the width of a black matrix (6) is made larger above the region between adjacent ITO transparent electrodes (3) and is made smaller above the region between adjacent Al reflective electrodes (4). 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.
