  • Patent number: 8325303
    Abstract: A liquid-crystal display device makes it possible to attach an optical element to a liquid-crystal display panel with high positional accuracy while avoiding or minimizing the enlargement of the picture-frame region (i.e., the non-display region) induced by the formation of markers on the panel and the increase of the fabrication cost. The panel comprises a main substrate, an opposite substrate, and a liquid crystal enclosed in a gap between the main and opposite substrates, wherein a polarizer plate is attached at least to the opposite substrate. Markers for attaching an optical element to the panel are formed at positions that overlap with the polarizer plate in a non-display region on the main or opposite substrate. Alignment direction regulators regulate the alignment of the liquid crystal molecules to a predetermined direction in the vicinities of the markers, allowing light to pass through at least the opposite substrate.
