Description

Display device, electronic device and manufacturing method of the display device The present invention relates to a display device, an electronic device, and a method for manufacturing a display device, and more specifically, to a display device, an electronic device, and a method for manufacturing a display device with improved reliability. Display devices such as televisions, monitors, smartphones, and tablets that provide images to users include display panels that display images. Various display panels are being developed as display panels, such as liquid crystal display panels, organic light emitting display panels, electro-wetting display panels, and electrophoretic display panels. Meanwhile, circuit boards can be interconnected through pads. For example, the pads of the circuit boards, the pads of the display panel, and the pads of each of the interconnected circuit boards must be sufficiently and completely connected to each other so that control signals and video signals can be transmitted to the display panel without distortion.
