Abstract
An EL display panel includes an organic EL device and a thin film semiconductor unit. The organic EL device includes a lower electrode, an organic light-emitting layer, and an upper electrode. The thin film semiconductor unit includes a first gate electrode, a gate insulating film, a first source electrode, a second drain electrode formed in a same layer as the first source electrode, a first power supply line formed in a same layer as the second drain electrode, and a first interlayer insulating film formed on the first source electrode and the second drain electrode. A gate line connected to the first gate electrode, a second power supply line formed in a same layer as the gate line and connected to the first power supply line, and an auxiliary line formed in a same layer as the second power supply line and connected to the upper electrode are included.
