摘要： A transflective LCD includes a LC layer sandwiched between a pair of substrates, and a pair of polarizing films. The LCD device includes a reflection area and a transmission area in each pixel, the transmission area having a reflection film. A retardation film has a first portion in the refection area between the reflection film and the LC layer, and a second portion in the transmission area between the LC layer and the rear polarizing film. The retardation film has a slow axis perpendicular to an initial orientation direction of the LC molecules upon absence of an applied voltage and perpendicular or parallel to the optical axis of the front polarizing film. The orientation of the LC molecules upon display of a dark state has a direction different between the reflection area and the transmission area.

摘要： In a liquid crystal panel, a reflective pixel electrode and a transmissive pixel electrode in a unit pixel are supplied with an image signal output from a data line drive circuit, the two mutually different scanning signals output from a scanning line drive circuit, and common signals output from a common line drive circuit. The phase of the image signal is set different from that of the common signal. Further, a period during which the two scanning signals are selected is set in one horizontal period, the ending of the selection period for one of the scanning signals is set to a point in time before an electrical potential of the common signal changes, and the ending of the selection period for the other scanning signal is set to a point in time after the electrical potential of the common signal changes.
