Description

Display device, method for manufacturing display device and electronic device including display device The present invention relates to a display device, a method for manufacturing a display device, and an electronic device including a display device. Generally, electronic devices such as smartphones, tablet PCs, digital cameras, laptop computers, navigation systems, and smart TVs include organic light-emitting display devices for displaying images. Organic light-emitting displays (OLEDs) are being applied to various products, primarily smartphones, due to their excellent characteristics in terms of brightness, driving voltage, and response speed, as well as their ability to be multi-colored. An OLED is composed of a display panel consisting of multiple pixels and a circuit unit that supplies signals to the display panel. The display panel consists of a substrate on which signal wiring for transmitting signals to implement an image and switching elements for driving pixels are formed. The circuit section consists of a control circuit board having a system that supplies signals and power for implementing an image, a controller that converts the signals received from the system into signals to be supplied to the display panel, and a driving circuit board that processes the signals converted by the control circuit board and transmits them to the display panel. The display panel and the driving circuit board can be electrically connected by a connecting member being joined to the display panel and the driving circuit board.
