Abstract: A flexible display device including a flexible display panel which displays an image, a strain gauge disposed in the flexible display panel, where the strain gauge senses a strain in the flexible display panel and generates a detection signal based on the sensed strain, a strain controller which receives the detection signal and outputs a strain compensation voltage based on the detection signal, and a strain compensation layer disposed on a surface of the flexible display panel and which receives the strain compensation voltage, where a thickness of the strain compensation layer may be controlled based on the strain compensation voltage such that a neutral plane of the flexible display device is maintained in a predetermined reference area in the flexible display panel.

Abstract: A display panel includes a first conductive layer including a first layer, a second layer, and a third layer sequentially stacked, and a second conductive layer on the first conductive layer and contacting the third layer. The first layer includes a first metal. The second layer includes the first metal and oxygen in a first composition ratio. The third layer includes the first metal and oxygen at a second composition ratio. The second composition ratio is smaller than the first composition ratio. Conductivity of the third layer is higher than conductivity of the second layer. The first composition ratio is a ratio of an atom percent of the first metal to an atom percent of oxygen in the second layer. The second composition ratio is a ratio of an atom percent of the first metal to an atom percent of oxygen in the third layer.
