  • Publication number: 20130088659
    Abstract: A liquid crystal display device includes a counter substrate, a TFT substrate, and a liquid crystal layer enclosed between the counter substrate and the TFT substrate. The TFT substrate has, on a counter surface thereof, a plurality of pixel electrodes arranged in a matrix. The counter substrate has, on a counter surface thereof, a single counter electrode having light transmission capability and facing the pixel electrodes. Voltages applied between the pixel electrodes and the counter electrode have a frequency of less than 60 Hz. The voltages between the pixel electrodes and the counter electrode are periodically reversed. The counter electrode includes a plurality of pixel counter regions facing the respective corresponding pixel electrodes, and a grid region between each of the pixel counter regions. The grid region is located further away from the TFT substrate than the pixel counter regions are.

  • Patent number: 6100958
    Abstract: A pair of electrode substrates are combined with a sealing material and spacers therebetween. A cell gap of a liquid crystal display element is controlled by maintaining the pressure in the space between the pair of electrode substrates at a predetermined pressure for a period of time as part of an evacuation process for the pair of electrode substrates, and pressing the pair of electrode substrates with atmospheric pressure. This prevents a sealing edge from becoming irregular due to bubbling of the sealing material, thereby providing the liquid crystal display element thus obtained with good linearity in the sealing edge. Moreover, since movement of the spacers near an exhaust port is prevented, irregular display coloring is eliminated, which enables the liquid crystal display element to have good display characteristics. Furthermore, since the sealing edge does not become irregular, the liquid crystal display element has excellent uniformity in the cell gap.
