  • Patent number: 10197872
    Abstract: A liquid crystal display apparatus includes a conductive paste, which connects a connection pad in a TFT array substrate and a transparent conductive film in a color filter substrate, and a ridge which is disposed adjacent to a conductive paste in a surrounding region of the TFT array substrate. A sealing member located between the color filter substrate and the TFT array substrate convexly extends in a direction from a display region to a surrounding region to form the ridge.
    Type: Grant
    Filed: September 27, 2016
    Date of Patent: February 5, 2019
    Assignee: Mitsubishi Electric Corporation

  • Patent number: 9817263
    Abstract: A liquid crystal display includes: a TFT array substrate; a counter substrate; a black matrix located on a surface of the counter substrate on the TFT-array-substrate side, the black matrix having, in a display region in which the pixels are disposed, a plurality of first openings formed at positions corresponding to the pixels, the black matrix being formed in a solid manner in a non-display region that is a periphery of the display region and is adjacent to the display region; a color material layer located on the counter substrate through the plurality of first openings and on the black matrix, the color material layer being formed in a solid manner in the display region and being formed to have the plurality of second openings as dummies in the non-display region; and a plurality of columnar spacers extended between the color material layer and the TFT array substrate.

  • Patent number: 8416372
    Abstract: The display device according to the present invention has a pixel, a TFT, a BM, and a colorant. A plurality of pixels are arranged in a matrix. The TFT is placed in the pixel. There are two kinds of positions of the TFT in the pixel. The position is common in each column. The BM has an aperture area and a TFT light-shielding part in the pixel. The TFT light-shielding part is placed to counter the TFT. The colorant is placed in the aperture area. Further, there are two or more kinds of the colors of the colorant. The color is common in each column. The shapes of the aperture areas in which the same color colorants are placed are the same.
