Abstract: A light emitting display device can include a first thin film transistor including a first semiconductor pattern, a first gate electrode, and first source and drain electrodes; a second thin film transistor including a second semiconductor pattern, a second gate electrode, and second source and drain electrodes; a storage capacitor including a first storage capacitor electrode and a second storage capacitor electrode; and a light emitting element layer electrically connected to the second thin film transistor. The first storage capacitor electrode can be disposed in the same layer as the first gate electrode, and the second storage capacitor electrode can be disposed in the same layer as the second gate electrode.
