The display apparatus may further include a first driver located under the power supply line and overlapping the seal, the first driver being located between the first thermally conductive layer and the display unit.

The display apparatus may further include a second thermally conductive layer connected to the power supply line and located between the power supply line and the lower substrate such that at least a part of the second thermally conductive layer and another end portion of the power supply line overlap each other.

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

The display apparatus may further include a second connection layer located between the power supply line and the second thermally conductive layer. The power supply line and the second thermally conductive layer may be connected to each other through the second connection layer.

The second connection layer is located between the seal and the display unit.

The display apparatus may further include a first driver located in an area between the first thermally conductive layer and the second thermally conductive layer located under the power supply line to overlap the seal and a second driver located in an area between the display unit and the second thermally conductive layer.

The second thermally conductive layer may extend toward the first driver.

The first driver may include an emission control driving circuit and the second driver may include a scan driving circuit.
