Display device and electronic device

Abstract

A display device includes: 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 and light receiving elements to correspond to the display area, wherein the circuit layer includes: pixel driving circuits connected to the light emitting elements; sensor driving circuits connected to the light receiving elements; data lines connected to the pixel driving circuits; read-out lines in a first area of the display area, and connected to, among the sensor driving circuits, a first sensor driving circuit in the first area; 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.
