  • Publication number: 20100323576
    Abstract: In a fabricating method of flexible display device, firstly, a sacrificial layer is formed on a first rigid substrate. Secondly, a first flexible substrate is formed on the sacrificial layer. The bonding force of the sacrificial layer absorbing a breaking-bond light may be broken and the first flexible substrate is transparent for the breaking-bond light. Moreover, the transmission rate of visible light of the first flexible substrate is larger than that of the sacrificial layer. Then, the sacrificial layer is illuminated by the breaking-bond light for breaking the bonding force of the sacrificial layer to separate the first rigid substrate from the first flexible substrate. Since the first rigid substrate has a high transmission rate of visible light, may be separated from the first flexible substrate by the first breaking-bond light with low energy, the cost of fabricating the flexible display device may display the images with real color.
