An exemplary liquid crystal display (100) includes gate lines (122), and data lines (123) cooperatively defining pixel units. Each pixel unit includes a first thin film transistor (TFT) (125), a second TFT (126), a first pixel electrode (127), and a second pixel electrode (128). Gate electrodes of the two TFTs are connected to one of the gate lines. A source electrode of the first TFT is connected to one of the data lines. A drain electrode of the first TFT is connected to the first pixel electrode. A source electrode of the second TFT is connected to the first pixel electrode. A drain electrode of the second TFT is connected to the second pixel electrode. A channel width/length ratio of the second TFT is such that a voltage of the drain electrode thereof is less than a voltage of the source electrode thereof when the second TFT is switched on.

An exemplary liquid crystal display (LCD) (200) includes a first substrate (210); a second substrate (230) opposite to the first substrate; a liquid crystal layer (250) sandwiched between the first substrate and the second substrate; a first common electrode (211), a first insulating layer (212), and pixel electrodes provided at an inner surface of the first substrate in that order; and second common electrodes (231) and floating electrodes (233) provided at the second substrate. The first common electrode and the pixel electrodes, and the second common electrodes and the floating electrodes, respectively produce two electric fields in the liquid crystal layer corresponding to each other. A combined electric field strength is uniformly distributed in the liquid crystal layer, so that all the liquid crystal molecules can be sufficiently twisted. Thus a viewing angle, a degree of chroma, and a transmission ratio of the LCD are improved.
