Abstract: Provided is a printed circuit board including a base substrate, first row pads, and second row pads. The base substrate has two sides, that can be adjacent, respectively extending in first and second directions. A plurality of pad group areas successively positioned along the first direction are defined on the base substrate. The first row pads are respectively disposed within the pad group areas and successively positioned along a third direction. The second row pads are respectively disposed within the pad group areas, successively positioned along the third direction, and spaced apart from the first row pads. Each of the second row pads is a predetermined distance from a corresponding one of the first row pads in the second direction.

Abstract: A flexible display panel includes a display area to display an image, and a non-display area disposed outside the display area. The non-display area includes a first portion and a second portion. The first portion extends from the display area, and includes a support layer disposed on a flexible substrate. The second portion extends from the first portion, and is bent from a plane of the first portion. A property of a material of the support layer in the first portion is different than the property of the material of the support layer in the second portion.
