Claim:
A thin-film transistor liquid crystal display device, comprising: a color filter substrate, a thin-film transistor substrate, and a liquid crystal layer interposed between the color filter substrate and the thin-film transistor substrate; the thin-film transistor substrate comprising a glass substrate and signal lines, scan lines, a first pixel electrode, a second pixel electrode, a common electrode, and a thin-film transistor formed on the glass substrate; the thin-film transistor comprising a gate terminal, a source terminal, and a drain terminal, the gate terminal being electrically connected to the scan line, the drain terminal being electrically connected to the signal line; a via hole being formed above the source terminal so that the source terminal is electrically connected through the via hole to the second pixel electrode; the signal line and the scan line being respectively arranged horizontally and vertically to intersect each other, the first pixel electrode and the second pixel electrode being located in a pixel display region that is enclosed and delimited by two adjacent signal lines and two adjacent scan lines that intersect each other; the common electrode being at least partially located in the pixel display region and extending in a direction of the scan line from one side of a pixel to an opposite side; the first pixel electrode and the second pixel electrode being sequentially formed on the common electrode; the first pixel electrode being spaced from the common electrode and the second pixel electrode in a vertical direction, the first pixel electrode partially overlapping the second pixel electrode; and the second pixel electrode forming a plurality of horizontally arranged slits, the first pixel electrode forming a hollow structure in a portion thereof that overlaps the second pixel electrode; whereby when the pixel display region displays a bright condition, the first pixel electrode and the second pixel electrode both apply voltages to the pixel display region to operate in brightness saturation.
