Abstract:
A liquid crystal display device comprising:a first substrate; a second substrate; a liquid crystal layer disposed between the first substrate and the second substrate; and a plurality of picture element regions each defined by a first electrode provided on a surface of the first substrate facing the liquid crystal layer and a second electrode provided on a surface of the second substrate facing the liquid crystal layer, wherein the first substrate has, on the surface thereof facing the liquid crystal layer, at least one first protrusion with an inclined side face correspondingly to each of the plurality of picture element regions, a portion of the liquid crystal layer included in each of the plurality of picture element regions is in a substantially vertical orientation state under application of no voltage, and includes at least a part of a first liquid crystal domain placed in a radially-inclined orientation state about the at least one first protrusion under voltage application, for producing a display by changing an orientation state of the liquid crystal layer in accordance with an applied voltage, and wherein each of the plurality of picture element regions has a plurality of portions having different thicknesses of the liquid crystal layer, at least one of the first substrate and the second substrate has level differences between the plurality of portions, and the level differences are covered with the first electrode or the second electrode.
