  • Patent number: 11037961
    Abstract: An array substrate comprises a display region provided with a thin film transistor circuit; a non-display provided with a drive circuit, at least one anti-static circuit and a dummy thin film transistor circuit. By disposing the dummy thin film transistor circuit and at least one of the anti-static circuits between the thin film transistor circuit and the drive circuit, the static electricity will not be released into an overlap region of a gate line and a polysilicon line, thereby solving technical problem that short circuit occurs between a gate layer and a polysilicon active layer.
    Type: Grant

  • Publication number: 20190129262
    Abstract: A liquid crystal display panel and a liquid crystal display device having the liquid crystal display panel are provided. The liquid crystal display panel includes a TFT array substrate and a color filter substrate disposed opposite to each other. The color filter substrate has a black matrix disposed thereon, the black matrix includes a first portion located in a display area and a second portion located in an non-display area. The second portion of the black matrix is provided with a groove surrounding the display area, the groove penetrates the black matrix in a thickness direction of the black matrix. The TFT array substrate is provided with a light shielding layer corresponding to a location where the groove is disposed, and a projection of the light shielding layer on the black matrix completely covers the groove.
