The pixel circuit of the display unit may include a thin-film transistor including a semiconductor layer, a gate electrode having at least a part that overlaps the semiconductor layer, and a first conductive layer including at least one of a source electrode and a drain electrode, a storage capacitor located between the gate electrode and the first conductive layer, the storage capacitor including an upper electrode having at least a part that overlaps the gate electrode, and a second conductive layer located on the first conductive layer.

The power supply line and the second conductive layer may be made of a same material.

The first thermally conductive layer and the upper electrode may be made of a same material.

The display apparatus may further include a first interlayer insulating layer located between the gate electrode and the upper electrode, a second interlayer insulating layer located between the upper electrode and the first conductive layer, and an inorganic insulating layer located between the upper electrode and the second conductive layer. The first interlayer insulating layer, the second interlayer insulating layer, and the inorganic insulating layer extend to the edge of the lower substrate, and the power supply line is located on the inorganic insulating layer.

Outer walls of the lower substrate, the upper substrate, and the seal may be aligned with one another.

The first thermally conductive layer may include a metal material that is less reactive than a metal material of the power supply line.
