Abstract: A display device includes a base layer; a backplane structure provided on the base layer and including a pixel circuit and a sensor circuit; a pixel layer provided on the backplane structure and including a light-emitting element connected to the pixel circuit and a light-receiving element connected to the sensor circuit; and an encapsulation layer configured to cover the pixel layer. The sensor circuit includes a first sensor transistor and a second sensor transistor connected between a readout line and a sensing power line to which sensing power is supplied, and a third sensor transistor connected to the light-receiving element. The backplane structure further includes a first connection pattern configured to connect the first sensor transistor and the second sensor transistor through contact holes. The sensing power line extends in a first direction.
