Description

Display device and electronic device including the same The embodiments relate to a display device and an electronic device including the same. Generally, a display device includes two or more electronic components. For example, electronic devices such as mobile phones, laptop computers, and televisions include an electro-optical panel that generates images, a main circuit board, and a connection circuit board, etc. These connection circuit boards can be electrically connected to a display panel and serve to transmit electrical signals to be applied to the display panel. A pad provided by a connection circuit board and a pad provided by a display panel can be joined. Meanwhile, with the recent expansion of the display area of display devices, the area where the connection circuit board can be placed is decreasing, and accordingly, a reduction in the area of the connection circuit board is required.
