Display device

A display device, comprising:

• an optical sensor;
• a display panel disposed on the optical sensor;
• and
• a touch sensing panel disposed on the display panel, and including a first sensing area corresponding to an area in which the optical sensor is disposed, and a second sensing area distinct from the first sensing area,
• wherein the touch sensing panel comprises:
• a plurality of first conductive patterns disposed in the first and second sensing areas and extending in a first direction;
• and
• a plurality of second conductive patterns disposed in the first and second sensing areas and extending in a second direction intersecting with the first direction,
• wherein first opening areas are provided by the first conductive patterns and the second conductive patterns that are disposed in the first sensing area,
• wherein second opening areas are provided by the first conductive patterns and the second conductive patterns that are disposed in the second sensing area, and
• wherein a surface area of each of the first opening areas is greater than a surface area of each of the second opening areas.
