  • Patent number: 9740054
    Abstract: In a liquid crystal display device including a TFT substrate and a counter substrate, when an organic passivation film is not formed in the TFT substrate, the distance between the TFT substrate and the counter substrate in the display area of a liquid crystal display panel is provided by a cylindrical spacer. Also, the distance in the area where pixels, scan lines, and image signal lines are not formed within the liquid crystal display panel is provided by the cylindrical spacer. In this case, it is necessary to form a mount. The layer structure of the mount is the same as that of the TFT substrate with which the cylindrical spacer in the display area comes into contact.

  • Patent number: 9703144
    Abstract: The disclosure provides a trichromatic illuminating module, comprising a circuit board and multiple illuminating units disposed on the circuit board. Each illuminating unit comprises a red chip, a green chip and a blue chip disposed on the circuit board, and intervals are set therebetween, a voltage is applied to the circuit board for illuminating the red chip, the green chip and the blue chip. There are more red chips than green chips and blue chips in each illuminating unit. Thus, the ratio of red light is increased. Since red light has the highest color gamut in the three primary colors, which causes it difficult for the saturation of color gamut. However, the ratio of red light of the disclosure is increased, such that the color saturation of white light emitted from the trichromatic illuminating module is increased. The disclosure also provides a backlight module and a liquid crystal display device.
