Abstract
An organic EL display panel having display pixels with an improved aperture ratio. A display pixel includes a control electrode line coupled to control electrodes of first and second transistors and a main electrode of a fourth transistor, and a power electrode line provided substantially in parallel with a data line and coupled to a main electrode of the first transistor. Channels of the first and second transistors are formed substantially in parallel with a scan line. A node of the control electrode line for coupling the control electrodes of the first and second transistors is arranged in a direction substantially perpendicular to that of the scan line, and a portion of the control electrode line extended to the main electrode of the fourth transistor is formed substantially in parallel with the power electrode line in a substantially vertical direction, and forms a capacitor together with the power electrode line.
