Patent number: 7495724Abstract: In order to achieve high display quality level in both of the reflective and transmissive regions without providing steps in the liquid crystal layer, in the reflective region for display with light reflected from a metallic auxiliary capacitance line, a part of a transparent pixel electrode overlaps the auxiliary capacitance line. An electric field generated between the pixel electrode and the counter electrode inclines liquid crystal molecules in the liquid crystal layer in a region where the pixel electrode overlaps the auxiliary capacitance line, and an oblique electric field generated between an end portion of the pixel electrode and the counter electrode inclines liquid crystal molecules in the liquid crystal layer in a region where the pixel electrode does not overlap the auxiliary capacitance line. Thereby, the phase differences in light passing through the reflective region is close to that in light passing through the transmissive region.Type: GrantFiled: January 29, 2007Date of Patent: February 24, 2009Assignee: Toshiba Matsushita Display Technology Co., Ltd.Inventors: Norihiro Yoshida, Jin Hirosawa, Arihiro Takeda
