  • Patent number: 7697106
    Abstract: A liquid crystal display device of the present invention has a structure in which vertically aligned liquid crystal is sealed between a TFT substrate and a CF substrate. Pixel electrodes in which slits are provided are formed on the TFT substrate, while cell gap holding spacers and domain defining projections are formed on the CF substrate. For example, positive type photoresist is coated on a common electrode. Then, first exposure is executed by using a mask for light-shielding spacer forming regions and projection forming regions, and then second exposure is executed by using a mask for light-shielding the spacer forming regions. Then, the photoresist is developed. Accordingly, the spacers and the projections, each having a different height, can be formed simultaneously.

  • Publication number: 20090200098
    Abstract: In an electric power steering device, if the temperature of a specific site that increases due to the driving of a steering assist motor exceeds a threshold, the motor current is controlled to be equal to or below a current restriction value. The temperature Toff of the specific site detected when an engine is stopped, and the current restriction value Ioff provided when the engine is stopped are stored into a storage. A temperature difference Ta between the temperature detected when a starter switch is turned on and the temperature Toff is computed. If the temperature of the specific site when the starter switch is turned on is above the threshold, the current restriction value is set to be equal to or above the current restriction value Ioff stored in the storage, according to the temperature difference Ta, over a time following the turning-on of the starter switch.

    Abstract: In a liquid crystal display device, liquid crystal molecules are oriented in a vertical direction to the first substrate and the second substrate by the first molecule orientation film and the second molecule orientation film, respectively, in a non-driving state. A structural pattern is formed so as to extend in a first direction parallel to a surface of the liquid crystal layer and so as to form, in a driving state, an electric field periodically changing in a second direction that is parallel to the liquid crystal layer and vertical to the first direction. The liquid crystal molecules substantially tilt in the first direction in the driving state.

  • Patent number: 7508468
    Abstract: A light blocking mask covering half of a picture element is formed on a first substrate. Thereafter, the first substrate and a second substrate are placed to face each other, and liquid crystals with negative dielectric anisotropy are sealed between these substrates, whereby a liquid crystal panel is formed. A polymer constituent which is polymerized by light is added in advance to the liquid crystals. Next, ultraviolet is irradiated from the side of the first substrate, and, after removing the light blocking mask, ultraviolet is once again irradiated. Thus, in picture element, a region where binding force with respect to liquid crystal molecules is large (a region where a threshold voltage in transmittance-voltage characteristics is high) and a region where binding force with respect to liquid crystal molecules is small (a region where a threshold voltage in transmittance-voltage characteristics is low) are formed.

  • Patent number: 7480027
    Abstract: A method of manufacturing a liquid crystal display device by sealing liquid crystals between the substrates relying upon a drop-injection method making it easy to determine a suitable dropping amount of the liquid crystals. The method comprises forming pillar spacers for maintaining a cell thickness on a CF substrate, measuring the height of the pillar spacers, determining the dropping amount of the liquid crystals based on the number of times of executing a step of forming an alignment film again effected for the CF substrate after measuring the height of the pillar spacers, dropping the liquid crystals in the determined dropping amount onto the CF substrate or onto a TFT substrate, sticking the CF substrate and the TFT substrates together in vacuum, and returning the pressure back to the atmospheric pressure to inject the liquid crystals into between the two substrates.

  • Publication number: 20080316406
    Abstract: When radiating light onto a liquid crystal composition containing a photosensitive material, the alignment of liquid crystal molecules is adjusted by applying a voltage to the liquid crystal composition layer, to achieve substantially orderly alignment of the liquid crystal molecules, or the alignment of the liquid crystal molecules is made uniform by adjusting the structure of the liquid crystal display device, or any display defect is driven out of the display area. When radiating light to the liquid crystal composition containing the photosensitive material, the alignment of the liquid crystal molecules can be adjusted so as to achieve substantially orderly alignment of the liquid crystal molecules, and the liquid crystal display device can thus be driven stably.
