Patent ID: 7164399

Claim:
A display device having a plurality of current driven self-emissive elements formed on a substrate and wherein display is achieved by controlling the current to the self-emissive elements, the display device comprising: a current control transistor provided corresponding to each of the self-emissive elements for controlling current from a power supply line to the corresponding self-emissive element, wherein one terminal of the current control transistor and of the power supply line are placed at different positions in the thickness direction and are connected through a contact, and the contact is connected to the power supply line at a connecting portion which protrudes from the power supply line; the connecting portion protrudes from the power supply line in a planer direction which is substantially parallel to the substrate surface; the current control transistor is a thin film transistor; and a portion of a line for a gate for supplying a control voltage to a gate electrode is placed at a position different from the power supply line in the thickness direction and overlapping the power supply line in the planar direction.
