Abstract:
A liquid crystal display (“LCD”) devise includes a white sub-pixel that has a smaller size than other sub-pixels thereby increasing the brightness and the color purities of the other colors, which improves image quality. An LCD device has the common and pixel electrodes on the same substrate and may be formed of a transparent conductive material to increase the brightness further.
Abstract:
In the preferred embodiment of the present invention, a ferroelectric LC layer is formed between first and second substrates of a LC panel. The LC panel is cooled at a low temperature, for example at −20° C., where the ferroelectric LC maintains a smetic phase. Due to the cooling, molecules are uniformly aligned for their early alignment state.

Abstract:
An LCD repair method repairs gate opens in a gate line where the gate line intersects with a data line or where the gate open exists at a position where it is not overlapped by a single pixel electrode. The method includes connecting a pixel electrode overlapping a portion of the opened gate line to the gate line, and forming a metal pattern to electrically connect two adjacent pixel electrodes.
Abstract:
A fabricating method of an array substrate for a transflective liquid crystal display device includes: sequentially depositing a first metal layer and an impurity-doped amorphous silicon layer on a substrate and etching the first metal layer and the impurity-doped amorphous silicon layer through a first mask process to form source and drain electrodes, a data line and an ohmic contact layer. An amorphous silicon layer, a first insulating layer and a second metal layer are sequentially deposited on the source and drain electrodes, the data line and the ohmic contact layer and etching the amorphous silicon layer, the first insulating layer and the second metal layer through a second mask process to form a gate electrode, a gate line and an active layer, the gate line defining a pixel region with the data line. A second insulating layer is formed on the gate electrode and the gate line. A reflective plate is formed on the second insulating layer at the pixel region through a third mask process, the reflective plate having a transmissive hole. A third insulating layer is deposited on the reflective plate and etching the third insulating layer through a fourth mask process to form a drain contact hole exposing the drain electrode and a transmissive groove corresponding to the transmissive hole. A pixel electrode is formed on the third insulating layer through a fifth mask process, the pixel electrode being connected to the drain electrode through the drain contact hole.
