Light emitting apparatus is disclosed including a thin film transistor, a capacitor and an organic electroluminescent device. The thin film transistor includes a semiconductive layer having spaced apart first and second doped regions defining first and second current carrying terminals with a channel therebetween, an insulating layer overlying the channel and a control terminal formed on the insulating layer. A portion of the control terminal overlies a portion of the first doped region to form the capacitor. The organic electroluminescent device includes a first terminal connected to the second current carrying terminal.
