In a seventh aspect, the first metal film may contain ITO.

In an eighth aspect, the second metal film may be formed in the same layer, and of the same material, as the second electrode is.

In a ninth aspect, the second metal film may contain silver,

In a tenth aspect, the light-emitting element layer may further include an edge cover covering an edge of the first electrode and having an opening to expose the first electrode. The analysis element does not have to be provided with the edge cover so that the first metal film is at least partially exposed.

In an eleventh aspect, the ground wire may be formed in the same layer, and of the same material, as the first metal film is.

In a twelfth aspect, the ground wire may intersect with, and extend out of, the sealing layer.

In a thirteenth aspect, the second metal film may be formed to cover a whole surface of the analysis layer.

In a fourteenth aspect, the display element may include a plurality of sub-pixels having the functional layer including a plurality of the light-emitting layers each emitting light in a different color. The analysis pixel may include a plurality of analysis sub-pixels each corresponding to one of the sub-pixels, each of the analysis sub-pixels including a corresponding one of a plurality of analysis light-emitting layers each corresponding to one of the light-emitting layers. The second metal film may be formed to cover one of four side edges of each of the analysis light-emitting layers of the analysis sub-pixels.

In fifteenth aspect, the second metal film may be formed in the same layer, and of the same material, as the second electrode is.

In a sixteenth aspect, the second metal film may contain silver.
