Abstract: A tiling display device includes a first display panel and a second display panel that is spaced apart from the first display panel by a horizontal tiling interval. The first display panel includes first to (n)-th pixel columns, and the second display panel includes first to (m)-th pixel columns. A first distance between the (n)-th pixel column of the first display panel and the first pixel column of the second display panel is less than a second distance between a (n−1)-th pixel column of the first display panel and the (n)-th pixel column of the first display panel.
