Abstract:

In a foldable display device according to an embodiment, a groove with a zigzag pattern is formed on a surface of an optical element. The optical element is bonded using an adhesive layer having a low modulus to mitigate stress and impact due to folding in a folding area of the device. According to an embodiment, a foldable display device includes: a panel assembly divided into a folding area and a non-folding area; and an optical element on the panel assembly including grooves with a zigzag pattern patterned on an upper surface of the optical element.
