Abstract: A pixel includes a light emitting element, a first transistor connected to the light emitting element, a second transistor connected between a data line and a first electrode of the first transistor, a third transistor connected between a gate electrode of the first transistor T1 and a second electrode of the first transistor, a fourth transistor connected between a gate electrode of the first transistor and an initialization power source, and a storage capacitor connected between the first power source and the gate electrode of the first transistor. A voltage provided through the data line is time divided into a data voltage provided to the gate electrode of the first transistor when both the second and third transistors turn on, and an on-bias voltage provided to the first electrode of the first transistor when the second transistor turns on and the third transistor turns off.

Abstract: Provided are a printed circuit board, a display device and a method of manufacturing a display device. The printed circuit board includes a base film including a first surface and a second surface, lead lines disposed on the first surface of the base film, and a first cover layer that covers at least a part of the lead lines and includes fill-in portions disposed between the lead lines. Each of the fill-in portions has a surface height less than a surface height of each of the lead lines with respect to the first surface of the base film.
