  • Patent number: 7486348
    Abstract: Light-emitting elements can be accurately directly opposed to the entrance surface of a light guide at an accurate distance therefrom, and can be mounted on a single side of a printed circuit board together with other electronic components, whereby the number of manufacturing steps and the thickness of a liquid crystal display device can be reduced. The light guide and the printed circuit board are disposed on the back surface of the liquid crystal display panel, and the respective light-emitting elements are inserted through through-holes formed to extend through the printed circuit board, with the light-emitting portions of the respective light-emitting elements opposed to the entrance surface of the light guide. The light-emitting elements, together with the other electronic components, are mounted on the printed circuit board from one side. Electrodes of the light-emitting elements are bridged and secured to a mounting surface of the printed circuit board.

  • Publication number: 20080309865
    Abstract: In a liquid crystal display panel, a liquid crystal layer is sandwiched between a TFT substrate and a color filter substrate. An ITO film is formed on a front surface of the color filter substrate. By supplying an electric current to the ITO film at the time of staring an operation of the liquid crystal display panel, a temperature of the liquid crystal layer is elevated to a level which allows the liquid crystal layer to perform a normal operation within a short time. By forming a plating electrode on two sides of the color filter substrate, it is possible to uniformly supply an electric current to the ITO film thus enabling uniform heating of the color filter substrate.
