Abstract

A display device includes a display panel and an input sensing layer. The display panel includes a base layer including a first island part, a second island part, and a connection part. Sensing patterns of the input sensing layer include a first sensing line pattern disposed on both the first island part and the second island part, and a second sensing line pattern disposed on the connection part. The connection part is an area to which stress is applied as the display device is modified in shape. The second sensing line pattern is disposed on an area of the connection part to which relatively less stress is applied.
