  • Publication number: 20150311351
    Abstract: For improved high-definition of liquid crystal display devices and the use thereof in bright places, luminance of backlights is being increased. Thus, when a light-shielding layer is employed for suppressing a light leakage current, characteristic fluctuations of transistors are caused, which may result in showing faulty display. In a dual-gate thin film transistor having a floating light-shielding layer, the layout is designed in such a manner that the film thickness of the insulating layer is equal to or more than 200 nm and equal to or less than 500 nm and that Sg/Sd becomes 4.7 or more, provided that an opposing area between the light-shielding layer and a drain region in a place at the outermost side of the active layer is Sd and the opposing area between the light-shielding layer and the gate electrode is Sg.

  • Patent number: 9077288
    Abstract: There is a problem that in an image sensor including an amplifier in each pixel, when a thin-film semiconductor is used as a transistor constituting the amplifier, voltage continues to be applied between source and gate of the transistor and thereby a threshold voltage value of the transistor varies, resulting in a variation of signal voltage. To solve the problem, a thin-film transistor formed with an oxide semiconductor is used as the transistor constituting the amplifier, and during a period other than a period of outputting an output of the amplifier, source potential of the transistor is controlled to be equal to drain potential thereof.
