Patent ID: 7602463

Claim:
A liquid crystal display device, comprising: a first substrate and a second substrate opposed to each other; a liquid crystal layer between the first substrate and the second substrate, liquid crystal molecules of the liquid crystal layer aligning with a first direction in an initial state; a first electrode and a second electrode between the liquid crystal layer and the first substrate, an electric field being generated between the first electrode and the second electrode and driving the liquid crystal layer; a sub pixel area including a reflective display area for reflective display and a transmissive display area for transmissive display, a thickness of the liquid crystal layer in the reflective display area being less than a thickness of the liquid crystal layer in the transmissive display area; and a retardation layer in between the liquid crystal layer and the second substrate selectively in an area corresponding to at least the reflective display area, the retardation layer having a phase-lag axis in a second direction intersecting the first direction, the first direction and the second direction defining an acute angle and an obtuse angle, wherein when the electric field is generated between the first electrode and the second electrode, the liquid crystal molecules move from alignment in the first direction in the initial state, through a region that corresponds to the obtuse angle, and into alignment with the electric field.
