    Abstract: A display device includes: a substrate; a display layer on the substrate; and a touch layer on the display layer, and including: a touch area; first sensor electrodes located along a first direction, and electrically connected to each other; second sensor electrodes located along a second direction crossing the first direction, and electrically connected to each other; and third sensor electrodes located along the first direction, and electrically insulated from the first and second sensor electrodes. In a first mode, the touch layer is to sense amounts of change in first capacitances between the first sensor electrodes and the second sensor electrodes, and in a second mode, the touch layer is to sense amounts of change in second capacitances between the first sensor electrodes and some of the second sensor electrodes, and amounts of change in third capacitances between the first sensor electrodes and the third sensor electrodes.

    Abstract: The fingerprint sensor may include: a light transmitting hole array layer including a plurality of light blocking patterns having a plurality of light transmitting holes to form light transmitting paths of light rays; a sensor layer including a plurality of photo sensors configured to sense light rays that pass through the light transmitting holes and are incident on the sensor layer; and metal patterns configured to apply electrical signals to pixels or the light blocking patterns. A gap between the light blocking patterns may overlap with at least some of the metal patterns.
