Abstract
An electronic device, including an array substrate, a pad portion disposed on the array substrate, and an integrated circuit disposed on the pad portion and comprising a bump portion. The pad portion includes a first sub-pad unit including a first pad having an inclined shape and a second sub-pad unit including a second pad having an inclined shape. The first pad and the second pad are symmetrically arranged with respect to an imaginary line that divides the pad portion. The pad portion is electrically connected with the bump portion.
