Claim Text:
1. A liquid crystal display device comprising: an active-matrix substrate; a counter substrate which faces the active-matrix substrate; and a liquid crystal layer which is interposed between the active-matrix substrate and the counter substrate, the liquid crystal display device including a plurality of pixels which are arranged in columns and rows to form a matrix pattern, wherein the active-matrix substrate includes: a thin-film transistor which is provided for each of the plurality of pixels and which includes a gate electrode, a source electrode, and a drain electrode; an upper electrode which is electrically connected to the drain electrode of the thin-film transistor; a lower electrode which is arranged under the upper electrode; and a dielectric layer which is arranged between the upper and lower electrodes, the counter substrate includes a counter electrode which faces the upper electrode, the upper electrode has first and second regions which have mutually different electrode structures, and a third region which electrically connects the first and second regions to the drain electrode, and the third region of the upper electrode includes a symmetrical connecting portion that is a conductive film pattern, of which the shape is substantially symmetrical with respect to a virtual line that splits each pixel into two adjacent regions in a row direction; wherein the active-matrix substrate further includes an interlayer insulating layer which is provided to cover the thin-film transistor, a contact hole is formed in the interlayer insulating layer and the dielectric layer so that the drain electrode is partially exposed in the contact hole and that the third region of the upper electrode is electrically connected to the drain electrode inside the contact hole, and the center of the contact hole is located off the virtual line.
