  • Patent number: 8366504
    Abstract: The present invention relates to a method of manufacturing a liquid crystal display device having a TFT substrate and a counter substrate, and prevents brightness unevenness from being caused by orientation film thickness unevenness. Orientation films for the TFT substrate (10) and the counter substrate (20) are formed by offset printing that is performed to transfer an orientation film material from a printing plate to the TFT substrate (10).The direction in which the printing plate for an offset printing machine rotates during offset printing is the long-axis direction of the TFT substrate (10) in the case of the TFT substrate (10) or the short-axis direction of the counter substrate in the case of the counter substrate. This ensures that brightness unevenness caused by orientation film thickness unevenness is inconspicuous even when the orientation film thickness unevenness is produced during offset printing.

  • Patent number: 8317563
    Abstract: Provided is a manufacturing method that allows even a PDP having high-definition cells to exhibit excellent image display performance with reduced power consumption by effectively preventing impurities from adhering to the protective layer. Specifically, in a pre-baking step, a back substrate 9 is baked at a pre-baking temperature. Here, a highest pre-baking temperature is set to be lower than a softening point of a sealing material. The back substrate 9 is superposed on a front substrate 2. Then, a sealing step is performed in a sealing atmosphere prepared by mixing a predetermined amount of a reducing gas with a non-oxidizing gas. The above enables the impurities attributed to organic components due to a sealing material paste to remain as low molecular components, whereby the impurities are evacuated and removed in an evacuating step performed after the sealing step. This prevents adherence of the impurities to the protective layer 8.
