摘要： In order to suppress noise in display, which would occur due to variations of inclination directions of liquid crystal molecules, and to improve display quality, a first structure in a shape having a discontinuous portion is provided to a first electrode, and a second structure is provided to a second electrode so as to face the discontinuous portion of the first structure. When a voltage is applied to the first and second electrodes to generate an electric field in a liquid crystal layer, the first structure controls the inclination directions of the liquid crystal molecules, and the second structure controls the inclination directions of the liquid crystal molecules existing in the discontinuous portion of the first structure. In the discontinuous portion of the first structure, the amount of light passing through the liquid crystal layer increases, and the liquid crystal molecules are aligned more vertically. Hence, light leakage is reduced.

摘要： 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.
