Abstract
A display device includes an array substrate and two electronic ink layers. The array substrate includes two active regions and a folding region that connects these two active regions. The two active regions are located at two opposite sides of the folding region. The two electronic ink layers are respectively located on the two active regions. The folding region of the array substrate is located below a gap between the two electronic ink layers. When the display device is at an unfolded state, two edges of the two electronic ink layers are adjacent to each other. When the display device is at a folded state, the two electronic ink layers are located between the two active regions of the array substrate.
