摘要： A thin and compact liquid crystal display device includes a liquid crystal display panel with first and second substrates, each having a display area and a non-display area, which are bonded to each other and separated from each other by liquid crystal material. A thermally conductive layer is formed on any one of the first and second substrates to prevent the liquid crystal material from becoming too cool, thereby preventing temperature-dependent formation of bubbles within the liquid crystal material. Such a liquid crystal display device may be simply fabricated.

摘要： The thin film transistor substrate increases an aperture ratio as well as prevents shorts between pixel electrodes by connecting drain electrodes of thin film transistors to storage electrodes to reduce the number of holes contacting the pixel electrodes. In the method of forming the thin film transistor substrate, drain electrode patterns are formed such that drain electrodes included in thin film transistors are electrically connected to storage electrodes included in storage capacitors. Accordingly, the number of holes contacting the pixel electrodes can be reduced so that an aperture ratio can be increased, or shorts between pixel electrodes can be prevented. Also, the drain electrode patterns are formed from the same conductive layer as the data lines supplying data signals to the thin film transistors, and a constant spacing between the two can be obtained to maintain a uniform parasitic capacitance therebetween and prevent deterioration of the data signal.

摘要： A liquid crystal display device structure is provided for testing display signal lines. The display structure improves sensitivity in detecting shorts or opens in data signal lines. In the display, a first detecting line commonly connects odd-numbered data signal lines of a liquid crystal display panel, and a second detecting line commonly connects even-numbered data signal lines of the liquid crystal display panel. First and second electrostatic discharge (ESD) preventing circuits are respectively connected to the odd and even-numbered data signal lines. A first electrode line commonly connects the first ESD preventing circuits and a second electrode line commonly connects the second ESD preventing circuits. Resistances are connected in series between the common electrode lines to increase a detectable critical resistance between the two detecting lines, to thereby improve sensitivity in signal line fault detection.

摘要： A liquid crystal panel driving apparatus is adapted to display a uniform level of luminance on an entire display area of a liquid crystal panel. The liquid crystal panel drive apparatus applies an alternative current signal to a storage line on the liquid crystal panel so that the signal voltage charged at each picture element on the first gate line is substantially equal to the signal voltage charged at each picture element on the second to last gate lines. As a result, the luminance level on a first line of the liquid crystal panel is substantially equal to that on the remaining lines and the luminance level is uniformly displayed on the liquid crystal panel, and further enhances the quality of a picture displayed on the liquid crystal panel.
