Abstract:
1. A liquid crystal device comprising first and second substrates and liquid crystal layers sandwiched between said first and second substrates, and including a reflective display area and a transmissive display area as pixel areas, the arrangement being such that said liquid crystal layer in at least said transmissive display area can be energized in a lateral electric field mode when a voltage is applied parallel to the plane of said substrates, wherein a first retardation plate and a first polarizer are stacked on a surface of said first substrate remote from said liquid crystal layer in an order toward said first substrate, and a second retardation plate, a third retardation plate, and a second polarizer are stacked on a surface of said second substrate remote from said liquid crystal layer in an order toward said second substrate; said first retardation plate and said third retardation plate have respective slow axes extending substantially perpendicularly to each other, and said second retardation plate and said liquid crystal layer in said transmissive display area have a slow axis and an orientation axis, respectively, extending substantially perpendicularly to each other; the retardation with respect to light applied from the direction normal to said first retardation plate to said first retardation plate is defined as Re the retardation with respect to light applied from the direction normal to said second retardation plate to said second retardation plate is defined as Re the retardation with respect to light applied from the direction normal to said third retardation plate to said third retardation plate is defined as Re the retardation with respect to light applied from the direction normal to said liquid crystal layer in said transmissive display area to said liquid crystal layer is defined as ReLC( Re
