Abstract:
1. A liquid crystal display apparatus comprising: a first substrate including a pixel electrode including a contact portion, main pixel electrodes extending in a second direction perpendicular to a first direction from two end portions of the contact portion in the first direction, and a connecting portion electrically connecting extended distal ends of the main pixel electrodes; a second substrate including a common electrode including main common electrodes extending substantially parallel to the main pixel electrode on either side of the main pixel electrode in the first direction, and secondary common electrodes extending between the main common electrodes between the pixel electrodes juxtaposed in the second direction; and a liquid crystal layer containing liquid crystal molecules held between the first substrate and the second substrate; wherein the first substrate includes source lines extending in the second direction; the main common electrodes arranged on either side of the pixel electrode oppose the source lines; the first substrate includes a first gate line and a second gate line extending in the first direction, an auxiliary capacitance line between the first gate line and the second gate line, and a drain electrode formed in the center of the pixel electrode in the first direction; the secondary common electrodes oppose the first gate line and the second gate line; the contact portion is formed in the center of a pixel in the first direction; the pixel electrode is surrounded by the common electrode in the pixel; a spacing between the pixel electrode and common electrode along the first direction are constant, and the main pixel electrodes and main common electrodes are alternately arranged along the first direction; the auxiliary capacitance line is closer to the second gate line than to the first gate line, and comprises a projection which projects toward the second gate line and opposes the contact portion; the main pixel electrodes extend from the contact portion toward the first gate line; and the drain electrode is electrically connected to the contact portion through two contact holes which are arranged along the first direction and are formed at symmetrical positions with respect to a centerline of the pixel.
