OG exemplary drawing
 
1. A display device, comprising:
an emission line;
a pixel configured to emit light in response to an emission signal received from the emission line;
a reset line; and
a light sensor configured to reset a voltage of a sensing node in response to a reset signal received from the reset line,
wherein at least a portion of the reset line overlaps at least a portion of the emission line in a plan view.
 
11. A display device, comprising:
a scan line;
a pixel connected to the scan line; and
a light sensor including a light receiving element, and a sensor circuit contacting an anode electrode of the light receiving element at a first contact point,
wherein the scan line is spaced apart from the first contact point, in a plan view.
 
20. An electronic device comprising:
a processor configured to provide input image data to a display device;
the display device configured to display an image based on the input image data; and
a power supply configured to supply power to the display device,
wherein the display device comprises:
an emission line;
a pixel configured to emit light in response to an emission signal received from the emission line;
a reset line; and
a light sensor configured to reset a voltage of a sensing node in response to a reset signal received from the reset line, and
wherein at least a portion of the reset line overlaps at least a portion of the emission line in a plan view.
