Abstract

A display device and a manufacturing method thereof are provided. The display device includes a first substrate, a second substrate, first signal lines, second signal lines, a first insulation layer, active components, a display medium, and ultrasonic transducers. The first insulation layer is located between the first signal lines and the second signal lines. Cavities are located in the first insulation layer having thin films located on the cavities. Each of the ultrasonic transducers includes first and second electrodes. A first electrode and a corresponding first signal line belong to a same layer and are electrically connected with each other. A second electrode and a corresponding second signal line belong to a same layer and are electrically connected with each other. A corresponding cavity and a corresponding thin film are sandwiched between the first and second electrodes.
