  • Patent number: 10551686
    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. This makes it possible to equalize the distance of the liquid crystal layer of the liquid crystal display panel without an increase in production cost, and to prevent uneven brightness or color.

  • Patent number: 10509256
    Abstract: The present invention provides a manufacturing method of a color filter substrate, in which a layer of photoresist layer of a negative photoresist resin material is first formed on the color filter film layer; then, back side exposure is conducted on the photoresist layer from the underside of the backing plate so that a part of the photoresist layer that is adjacent to the backing plate gets cured for subsequently forming a planarization layer; afterwards, a mask is used to conduct front side exposure on the photoresist layer from the backing plate to form post spacers; and finally, the photoresist layer that has been subjected to exposure twice is subjected to development to remove a portion of the photoresist layer that has not been cured so as to form, simultaneously, a planarization layer and post spacers located on the planarization layer.

    Abstract: A liquid crystal display device is a curved liquid crystal display device including a liquid crystal panel which includes a liquid crystal, glass substrates which sandwich the liquid crystal, main spacers, and sub spacers. The main spacers come into contact with both of the glass substrates and keep an interval between the glass substrates. The sub spacers are arranged to come into contact with only one of the glass substrates, and, when the main spacers elastically deform and the interval between the glass substrates becomes close, come into contact with both of the glass substrates and keep the interval. The density of the main spacers per unit area in the display region is higher at a center portion than at both end portions in a curving direction of the liquid crystal panel.
