An electronic device includes a circuit board, a driving member, and a working member. The circuit board has a board body, conductive lines, and conductive pads. The board body has a working surface. The driving member includes a substrate, a thin film circuit, a thin film element, and connection pads. The thin film circuit corresponds to thin film element and is electrically connected to the connection pads, and the connection pads are connected to partial conductive pads. The substrate has a first top surface. The working member has at least one electrode electrically connected to one of the conductive pads. The working member has a second top surface. A first height is defined between the first top surface and the working surface, and a second height is defined between the second top surface and the working surface. The second height is greater than or equal to the first height.
