Abstract
A liquid crystal display device includes a first substrate and a second substrate opposed to each other with a liquid crystal layer therebetween, in which a first electrode and a second electrode are provided on a side of the first substrate opposed to the liquid crystal layer and the liquid crystal layer is driven by means of an electric field generated between the first electrode and the second electrode. A reflective display area for reflective display and a transmissive display area for transmissive display are formed in a sub pixel area. The thickness of the liquid crystal layer in the reflective display area is greater than the thickness of the liquid crystal layer in the transmissive display area. A retardation layer is selectively formed in an area corresponding to at least the reflective display area on a side of the second substrate opposed to the liquid crystal layer.
