Abstract
A stacked structure of a display device is capable of preventing conductive noise due to signal interference by isolating analog and digital output stages and a ground stage onto different layers. A driving device of an organic light emitting display has a scan driver for applying a plurality of scan signals, a data driver for applying a plurality of data signals, and a controller for providing a gradation voltage to the data driver and a scan signal to the scan driver. The stacked structure includes a ground layer, an analog signal-transmission layer for transmitting an analog signal, a digital signal-transmission layer for transmitting a digital signal and a power supply transmission layer for transmitting a power supply voltage. Each of the layers is formed on a different layer. Further, the stacked structure further includes a first mounting layer at a front of the structure on which circuits are mounted and a second mounting layer at a rear thereof on which circuits are mounted. The stacked structure further includes insulating layers formed between the respective layers to insulate the layers.
