PURPOSE: A printed circuit board is provided to minimize an electrode line to be damaged, bent, and torn of by minimizing the damage of a corner area to change a progressive direction of the electrode line. CONSTITUTION: A printed circuit board comprises a first substrate(100) and a second substrate(200). The second substrate includes a corner area(A) for freely wiring in an electronic device having the printed circuit board. A progressive direction of an electrode line(80) is changed in the corner area. The corner area is formed in a left side or right side of the second substrate. The first substrate is divided into a first area(100a) including light emitting devices(60a-60n) and a second area(100b) including the electrode line for the light emitting device. The light emitting device and the electrode line are arranged in different areas. The light emitting device is mounted on the first area. |
