The second thermally conductive layer 90 has no issues regarding cutting, unlike the first thermally conductive layer 80. Accordingly, the second thermally conductive layer 90 may be integrally formed without a patterned portion. The second thermally conductive layer 90 may extend toward an edge of the lower substrate 100 that is opposite to a display area in order to minimize damage to an adjacent driving circuit that could be caused by heat transferred to the second thermally conductive layer 90. The second thermally conductive layer 90 may be spaced apart from the first light-emitting driving circuit 30 by a predetermined interval D.

FIG. 10 illustrates a cross-sectional view of a portion of a display apparatus 3 according to another embodiment. FIG. 10 illustrates a portion of the peripheral area PA including the edge 100E of the lower substrate 100 and a part of the seal 400.

The embodiment of FIG. 10 may be the same as one of the above embodiments except for structure of the first connection layer 82.

As shown in FIG. 10, the first connection layer 82 may extend to the edge 100E of the lower substrate 100. The end surface 82E of the first connection layer 82 and the edge 100E of the lower substrate 100 may be aligned with each other.
