| 20100201932 | LIQUID CRYSTAL DISPLAY DEVICE - An IPS liquid crystal display device having comb-teeth-shaped pixel electrodes which can prevent image retention while ensuring reliability of through hole portions and reliability of terminal area is provided. In an IPS liquid crystal display device having comb-teeth-shaped pixel electrodes, image retention occurs when rubbing is not applied to a gap defined between the comb-teeth-shaped electrodes. The pixel electrodes, through holes which supply a voltage to the pixel electrodes and a terminal area are formed of an ITO film. By setting a film thickness of only the ITO film for forming the pixel electrodes smaller than a film thickness of the ITO film formed at the through holes and a film thickness of the ITO film for forming the terminal area, it is possible to sufficiently apply rubbing to a gap between the comb-teeth-shaped electrodes which constitute the pixel electrodes. | 08-12-2010 |

| 20100309416 | LIQUID CRYSTAL DISPLAY DEVICE - There is provided a liquid crystal display device having color filters on a side of a TFT substrate, in which an orientation film is formed by inkjet printing. The formation of an orientation film by inkjet printing is more advantageous than the conventional flexographic printing in terms of the production cost. It is necessary, however, to reduce the viscosity of the orientation film to be applied by inkjet printing. For this reason, first and second orientation film stoppers are formed between a display area and a sealing portion in a TFT substrate, to prevent the orientation film from flowing to an end of the TFT substrate. The orientation film stoppers are formed by the overlapping of color filters. A profile of the orientation film is defined by the first orientation film stopper. The second orientation film stopper is formed to ensure that the orientation film does not flow to the outside. | 12-09-2010 |
| 20100309421 | DISPLAY DEVICE - In a liquid crystal display device it is desirable to test in the state of TFT substrates, without reducing the number of TFT substrates to be obtained from one mother TFT substrate, and without increasing the overall size of the TFT substrates. Test terminals are formed on the outside of terminals for driving the liquid crystal display device. The test terminals of the specific TFT substrate are formed in another TFT substrate just below the specific TFT substrate. The area in which the test lines are formed is a space in which a sealing material is formed, between the display area and an end of the lower TFT substrate. Thus, the size of the TFT substrates is not actually increased. A test line area is not separately formed and not discarded, so that the number of TFT substrates to be obtained from one mother TFT substrate is not reduced. | 12-09-2010 |
