An improved electron emission display apparatus includes a data driving circuit having a plurality of interconnected data driving devices. Gray-level data output from a panel control circuit is input to a gray-level data input port of a first driving device. Since the gray-level data input port of an i-th (i=2 through 20) data driving device is electrically coupled with a gray-level data output port of an (i-1)-th data driving device, the gray-level data may be applied to all the gray-level data input ports of the remainder of the driving devices. Consequently, a circuit substrate configuration of a driving apparatus may be improved even when the driving apparatus is applied to driving a high-resolution electron emission display panel.
