  • Publication number: 20090231502
    Abstract: In a liquid crystal display device of the present invention, when a display voltage is applied to picture element electrodes, each picture element electrode forms a plurality of domains in which liquid crystal molecules align themselves in different directions. The picture element electrodes are formed such that their edge portions on the opposite sides of a picture-element-electrode aperture portion formed between the picture element electrodes face parallel to each other with a certain interval. A source bus line is provided along the picture-element-electrode aperture portion formed between the picture element electrodes. The source bus line is disposed beneath the picture element electrodes and at the edge portions of the picture element electrodes by overlapping therewith in a direction of thickness.

  • Publication number: 20090213053
    Abstract: A liquid crystal display device includes a plurality of pixels each connected to a signal line via a switching element. Each pixel includes first and second sub-pixels having voltage vs. luminance characteristics different from each other with respect to a signal voltage supplied from the signal line. A threshold signal voltage of the first sub-pixel is lower than that of the second sub-pixel. The pixels form color display pixels which are red, green pixel and blue pixels. Where the area ratio of the first sub-pixel in each of the red, green and blue pixels is SR1, SG1 and SB1, and the ratio of the lighting-up time period of the first sub-pixel of each of the red, green and blue pixels in one vertical scanning period is TR1, TG1 and TB1, the relationship of (SR1×TR1)>(SG1×TG1)>(SB1×TB1) holds.

  • Publication number: 20090125836
    Abstract: An object of the present invention is to provide an image output device capable of performing a screen switching without causing a user to feel discomfort or anxiety. An in-vehicle image output device 101 receives moving image data from a content storing section 110 via a communication section 102, and the received moving image data is decoded in a decoding section 103. An effect processing controlling section 106 calculates, as an effect processing execution time, a time period required from when an instruction to reproduce the moving image data is received to when the reproduction of the moving image data starts, and causes an effect processed image generating section 107 to generate an image in which a current screen is shifted to a subsequent screen. After displaying the effect processed image, the control section 105 changes an output so as to display an image of the moving image data.
