A display panel using a light emitting device is provided to prevent thermal deformation, reproduce various colors, and easily control light amount by using the light emitting semiconductor as a back light. At least one or more basic units from first to nth including light emitting semiconductors from first to mth connected in series in the same direction are formed in parallel in a printed circuit board(10). Two power supply lines are formed in the printed circuit board and serve as a conductor pattern for connecting the first light emitting semiconductor with the mth light emitting semiconductor included in each one of the first to nth basic units. A light guide plate(20) is installed adjacent to a light-emitting surface of the light emitting semiconductor mounted in the printed circuit board to diffuse light generated from each light emitting semiconductor with uniform illumination. |
