Abstract
An electro-luminescent (EL) display includes a gate line, first to third data lines defining first to third pixel regions, respectively, the first to third data lines crossing with the gate line, first to third power supply lines passing through the first to third pixel regions, switching devices connected electrically to the gate line and the data lines, the switching devices formed in the respective pixel regions, driving devices in the respective pixel regions wherein each gate and source of the driving devices are connected to each electrode of the switching devices and the power supply lines, respectively, first to third EL diodes connected to drains of the driving devices, the first to third EL diodes corresponding to the first to third pixel regions, respectively, and first to third power source supply terminals connected to the first to third power supply lines, respectively. Accordingly, the R, G, and B pixels may be independently driven without a complicatedly-designed data driving circuit, thereby simplifying the data driving circuit as well as reducing the product cost.
