  • Patent number: 10546516
    Abstract: When display panels are arranged to form a tiled-type display apparatus, the precision of the spaces between adjacent display panels is to be increased, and display quality is to be enhanced. A display apparatus includes display panels and space forming members. Pixels are arranged on the display panels. Space forming members are disposed between a display panel and a display panel, and form a space between the display panels. As spaces are formed by the space forming members, the spaces between the display panels are prevented from changing. Thus, appearances of joints are also prevented.
