  • Patent number: 7161183
    Abstract: A method of manufacturing a liquid crystal display device is intended to decrease the number of manufacturing steps. The liquid crystal display device is arranged so that in each pixel area provided on a liquid-crystal-side surface of one of a pair of substrates disposed to oppose each other with a liquid crystal interposed therebetween, a signal from a drain line is applied to a pixel electrode via a drain electrode and a source electrode which are formed in a layer overlying a semiconductor layer of a thin film transistor, by the supply of a scanning signal from a gate electrode which is positioned as an underlying layer with respect to the semiconductor layer.

  • Publication number: 20040061671
    Abstract: A display apparatus is arranged in a manner that each pixel includes a light emitting element for emitting light in response to a current flowing therein, a first switching element for fetching luminance information into a pixel from a signal line, and a second switching element for controlling a current amount to be supplied to the light emitting element in accordance with the luminance information thus fetched; the luminance information is fetched by fetching the signal voltage of the signal line when a scanning line connected to the pixel is selected; and the luminance information thus fetched in each of the pixels is kept in a capacitor even after the scanning line connected to the pixel is place in a non-selection state.
