A display device includes a light supplying unit generating light and a liquid crystal panel having a liquid crystal layer including liquid crystal molecules aligned substantially parallel to the plane of a pair of substrates by anti-parallel rubbing when no voltage is applied to the panel. Bias voltage corresponding to maximum gray level of the panel is determined between threshold voltage of the liquid crystal layer and 40% of maximum voltage.

A longitudinal axis of the liquid crystal molecule is inclined at an angle with a longitudinal pixel electrode.

Thin film transistor array panel and method for manufacturing the same

A display panel is provided. The display panel includes a substrate and a pixel electrode disposed on the substrate and having a pair of first primary edges facing each other and a pair of second primary edges connected to the first primary edges and facing each other, wherein the second primary edges include a plurality of protrusions of the pixel electrode having the shape of sawteeth.

Display panel and liquid crystal display apparatus including the same

A liquid crystal display includes: a substrate; a pixel electrode disposed on the substrate and having a first subpixel electrode and a second subpixel electrode; and a common electrode facing the pixel electrode, wherein the first subpixel electrode has a pair of bent edges substantially parallel to each other, the second subpixel electrode has a pair of bent edges substantially parallel to each other, and the second subpixel electrode has a height greater than a height of the first subpixel electrode.

Liquid crystal display

An additional capacitor ('sharing capacitor') is provided for each pixel of a liquid crystal display to store the previous voltage on the pixel electrode (i.e. the voltage obtained in the previous frame). At an opportune time after the pixel electrode has begun to charge for the current frame, the sharing capacitor's electrode is coupled to the pixel electrode to combine the pixel electrode's voltage with the sharing capacitor's voltage. As a result, the pixel electrode's voltage is changed to take into account the previous voltage so as to increase the liquid crystal's response speed. More particularly, the sharing capacitor's voltage changes the pixel voltage to provide a greater voltage overshoot or undershoot when the pixel color is changed a lot, so as to increase the liquid crystal response time. Therefore, greater response speed is provided at low power.

Array panel and method of driving the same

In a display panel, main and sub pixel electrodes are connected to first and second drain electrodes of a thin film transistor, respectively, to receive a data voltage during a 1 H period as main and sub pixel voltages. A main storage electrode overlaps the main pixel electrode to receive a first common voltage that varies with the gate pulse and the polarity of the data voltage. A sub storage electrode overlaps the sub pixel electrode to receive a second common voltage that is uniformly maintained at a constant voltage level. The sub pixel voltage is uniformly maintained by the second common voltage, but the main pixel voltage is shifted up or down by the first common voltage. Thus, the main pixel voltage may have a voltage level higher than that of the sub pixel voltage.

Display panel

A display apparatus includes a substrate, in which first and second pixel areas are defined. A first pixel electrode including a first main pixel electrode and a first sub-pixel electrode is formed in the first pixel area and a second pixel electrode including a second main pixel electrode and a second sub-pixel electrode is formed in the second pixel area.
