摘要： In a liquid crystal display device of the active matrix type using in-plane switching (IPS), with at least four transmission regions being formed within a single pixel area surrounded by neighboring gate wiring lines and neighboring drain wiring lines disposed in a direction transverse to the drain wiring lines, a multilayer structure formed of two layers of conductive films with an insulating film sandwiched therebetween is provided at a pixel electrode extending from either one of the neighboring gate wiring lines toward the interior of the pixel and causes one of these two-layer conductive films (i.e. lower pixel electrode placed on the substrate side) is configured to bend or “crank” into a hook-like shape at a central portion of the pixel areas while letting its planar shape be adjacent to one of the neighboring drain lines at the half of the pixel area and also letting it be adjacent to the other of the neighboring drain lines at the other half, thereby widening the viewing angle of an image to be visually displayed on the liquid crystal display device and also brightening the image.

摘要： An active matrix type liquid crystal display device includes, in each pixel, a semiconductor layer of a thin film transistor, a first insulating film formed on the semiconductor layer, a gate line formed on the first insulating film, a second insulating film formed on the gate line, and a drain line formed on the second insulating film. The bottom side of the gate line is opposed to the semiconductor layer with the first insulating film interposed therebetween, and the top side of the gate line is covered with a metal electrode formed on the second insulating film by the same process as used to form the drain line, whereby leakage electric fields from the gate line are shielded. Particularly when an IPS type liquid crystal display device using low temperature poly silicon TFTs is constructed in the above-described manner, a wide viewing angle and a bright display image are obtained.

摘要： Below a transparent pixel electrode, an opaque pixel electrode is arranged while sandwiching an insulation film between the transparent pixel electrode and the opaque pixel electrode. A common electrode is arranged below the opaque pixel electrode thus forming a holding capacitance between the common electrode and an opaque metal electrode. In case when the pixel is divided into four or more portions, an interval between the pixel electrode and the common electrode is set to an unequal pitch size or an unequal electrode width within one pixel.

摘要： Provided is a liquid crystal display device, including: a data line; a plurality of pixel circuits; an output grayscale value generating circuit for outputting an output grayscale value obtained by correcting a display grayscale value indicating a grayscale potential having one of positive polarity and negative polarity; and a data-line driving circuit for selectively outputting an output potential having one of positive polarity and negative polarity corresponding to the output grayscale value to the data line. The data-line driving circuit outputs the potential so that the positive-polarity output potential corresponding to a smallest output grayscale value becomes lower than a positive-polarity grayscale potential indicated by a smallest one of the display grayscale values and that the negative-polarity output potential corresponding to the smallest output grayscale value becomes higher than a negative-polarity grayscale potential indicated by the smallest one of the display grayscale values.

摘要： A liquid crystal display device includes a plurality of pixel circuits, data lines, and a data-line driving circuit connected to the data lines. Each of the pixel circuits includes a pixel capacitance having one end provided with a common potential.
