Abstract: A display device includes a display member and a touch member. The display member is configured to generate an image. The display member includes a folding area configured to be folded along a folding axis, and another area adjacent to the folding area. The touch member is configured to detect a touch interaction association with the display member. The touch member includes a touch sensor, and a signal line electrically connected to the touch sensor. The touch sensor is a mesh-shaped touch sensor. A mesh line of the mesh-shaped touch sensor crosses the folding axis. A minimum angle between the folding axis and the mesh line is less than 90 degrees.
