Display device and electronic device

A display device comprising:

• a base layer, in which a display area and a non-display area are defined;
• a circuit layer on the base layer;
• and
• an element layer on the circuit layer, and including light emitting elements corresponding to the display area, first light receiving elements in a first area of the display area, and second light receiving elements in a second area of the display area,
• wherein the circuit layer includes:
• pixel driving circuits connected to the light emitting elements;
• first sensor driving circuits connected to the first light receiving elements;
• second sensor driving circuits connected to the second light receiving elements;
• data lines connected to the pixel driving circuits;
• read-out lines in the first area of the display area, and connected to the first sensor driving circuits;
• and
• a connection line part connecting the read-out lines to a read-out circuit, and
• wherein the connection line part includes:
• first connection lines in a second area of the display area;
• and
• second connection lines connecting the first connection lines to the read-out lines.
