Display device

A display device, comprising:

• a first transistor connected to a data line and a scan line to supply a data signal to a first node;
• a storage capacitor having one electrode connected to the first node and the other electrode connected to a second node;
• a light emitting element having one electrode connected to the second node and the other electrode connected to a second power source;
• a second transistor supplying a current corresponding to a voltage applied to the first node from a first power source to the second power source via the light emitting element;
• a third transistor connected to the second transistor and an emission control line;
• a first blocking layer connected to the first transistor;
• a second blocking layer connected to the second transistor;
• and
• a third blocking layer connected to the third transistor,
• wherein each of the first to third transistors includes an active pattern, a gate electrode on the active pattern, and source and drain electrodes, each connected to the active pattern, and
• wherein the first blocking layer and the third blocking layer are connected to a same configuration of a corresponding transistor.
