Abstract
Provided are a display panel and a display device. After deposition of a thin-film transistor layer and a display layer in which emitting devices are disposed, a sensing layer including a piezoelectric material is disposed under the thin-film transistor layer to facilitate implementation of a display panel having built-in piezoelectric devices. Further, as thin-film transistors for ultrasonic sensing and thin-film transistors for display driving are disposed in different layers, a display panel capable of ultrasonic sensing in an active area may be provided without affecting a display resolution or implementation of display pixels.
