Abstract:
1. A light emitting device comprising: a substrate; a gate signal line over the substrate; a power source supply line over the substrate; a first thin film transistor over the substrate, the first thin film transistor electrically connected to the gate signal line; a second thin film transistor over the substrate, the second thin film transistor electrically connected to the power source supply line; an interlayer insulating film over the first thin film transistor and the second thin film transistor, a first electrode over the interlayer insulating film, the first electrode electrically connected to the second thin film transistor through a contact hole formed in the interlayer insulating film; and a light emitting layer disposed adjacent to a side edge of a bank, the light emitting layer formed over the first electrode, and a second electrode over the light emitting layer, wherein the light emitting layer has a flattened upper surface over the contact hole, wherein the light emitting layer does not extend to an upper surface of the bank, and wherein the gate signal line and the power source supply line are parallel to each other.
